Tweetable Quotes

"When you're in a hole, the bomb doesn't count the pips. His point was if you're doing a job it doesn't matter if you're a major or the lowest rank. The bomb doesn't care. You're a team, do it together."

"I think that in many ways, that transition from the world of semiconductors came through a series of other startups looking at things like aircraft efficiency and really starting to look at what can we do not to change the way people have to live, but to bring things into line to make what people need achievable within the bounds of what the world can provide."

"Plasma is this fourth state of matter. It's a high energy state and instead of having these very solid bonds that the ice had, they became looser with the water, looser again with the gas and we actually start to split up the molecules so they become separate ions and at that point a lot of interesting things happen."

2025 Precision Ag Report

Transcripts

Speaker:

$680 million poured into precision ag last year.

Speaker:

Autonomous weeding robots dominated, and John Deere made 2 acquisitions in 3

Speaker:

months. A food company, not an equipment maker, bought a

Speaker:

robotics startup to protect its own supply chain. The deals are

Speaker:

accelerating, the money is moving, and the winners are already separating from the

Speaker:

pack. If you're investing, building, or buying in this space,

Speaker:

you need the full picture before your competitors get it. The 2025

Speaker:

Precision Agriculture Intelligence Report From iGrow News is now

Speaker:

available. Get your copy today at

Speaker:

igrownews.com/precision. As an

Speaker:

industry, we've got to get this right. I think whether

Speaker:

it's glasshouse, vertical farms, or whatever, we've got to move

Speaker:

the agricultural output forwards. And I think

Speaker:

we're a very, very big part of that story. I think the staggering

Speaker:

number is the story of agriculture using 70% of the Earth's

Speaker:

water. And now we're going to increase agriculture by 50%, and you're

Speaker:

going, well, that means there's not going to be any Perrier, doesn't it? So

Speaker:

we've got to do something about it.

Speaker:

Welcome to the Vertical Farming Podcast, weekly conversations

Speaker:

with fascinating CEOs, founders, and agtech

Speaker:

visionaries. Join us every week as we dive deep into the

Speaker:

world of vertical farming with your host, Harry Duran.

Speaker:

Speaker:

podcasting since 2014 with my first show, Podcast Junkies, and founder

Speaker:

of our full-service podcast agency, Fullcast. In case you missed

Speaker:

last week's episode, we had a great conversation with Robin Vincent of

Speaker:

Kenobi Technologies. We talked about his navigation of the

Speaker:

CEO journey, his love for tech and electronics, Ubuntu

Speaker:

wellness and growing nutritious food, conference travel, networking

Speaker:

discussions, energy efficiency in farming, loneliness, and the

Speaker:

challenges of entrepreneurship. As you might imagine, covering a lot of

Speaker:

bases, and that one's been well received. Make sure you check that out if you

Speaker:

have not already. This week we speak to Ralph Weir of Xanadu.

Speaker:

Ralph grew up in Scotland and has traversed a really fascinating journey from the world

Speaker:

of semiconductors and mobile television all the way to vertical farming.

Speaker:

And his story is not just a narrative of his own evolution, but a testament

Speaker:

to the power of adaptability and innovation. We talk about his roots,

Speaker:

his father's profound influence on his life, and a chance

Speaker:

encounter with the world of agtech, which shaped his incredible

Speaker:

journey. Under Ralph's leadership, Zaindu is revolutionizing the farming landscape using

Speaker:

plasma technology, which is something that was new to me, and I was really interested

Speaker:

to deep dive on this. We talk about their trailblazing work and how they're

Speaker:

leveraging plasma to enhance crop growth, optimize seeds per specific

Speaker:

growing systems, and significantly reduce costs, which is really

Speaker:

helpful for transforming vertical farming into an accessible venture for

Speaker:

small-scale farmers, which is something that's near and dear to my heart. We talk a

Speaker:

little bit about differential pricing and what he's called snooze mode

Speaker:

for seasonal planting, which is an interesting concept, and he'll explain

Speaker:

that in this episode. Despite the numerous challenges posed by the pandemic and

Speaker:

Brexit, Zaindu's resilience and commitment to their mission

Speaker:

remained unwavering, and we talked about how he was able to navigate the

Speaker:

complexities of leadership, all the challenges of tech,

Speaker:

and how to future-proof what they're doing in the vertical farming space.

Speaker:

It's truly an inspiring story of innovation, resilience,

Speaker:

and a passion for the environment as well, so I know you'll get a lot

Speaker:

out of this. If you enjoy this episode or any past episodes, then please

Speaker:

Ralph Weir, CEO of Zayindoo, thank you so much for joining me on

Speaker:

the Vertical Farming Podcast. Thank you, Hari. I'm really excited to be

Speaker:

here. Oh, that's very nice of you. Thank

Speaker:

you so much. When did you first hear about the show? It was

Speaker:

actually through a friend who said you should be listening to some of these. Yeah,

Speaker:

it's probably, oh, 6 months ago.

Speaker:

Oh, it's amazing what you can get with CarPlay in the car on the drive

Speaker:

home. It's great. So I should be thanking your friend as well.

Speaker:

You know Mickey. Yeah, yeah, yeah. And where are you

Speaker:

calling in from? So yeah, I'm coming from Loughborough, which is

Speaker:

between Nottingham and Leicester in the UK. It's in the

Speaker:

middle of the sort of the industrial heartland of

Speaker:

England. Okay. There's a lot of engineering around here.

Speaker:

A lot of science. We're actually a spin-out from the university here,

Speaker:

which is where the company was originally founded. What, was

Speaker:

that where you grew up as well? Oh no, no, no, no.

Speaker:

I'm from the west coast of Scotland. Oh, okay. It's a very

Speaker:

different part of the world. It's a land of fjords and

Speaker:

mountains. My grandfather had a croft up there,

Speaker:

so that is a bit of a connection with The whole

Speaker:

farming community, although of course a croft with a few sheep and a few

Speaker:

crops is very different to what we have today. Yeah. So

Speaker:

yes, different. Is croft Scottish for farm? It's like a

Speaker:

very small holding. So the village he had his

Speaker:

croft in, there was a small house which was sort of like one

Speaker:

bedroom, one other room, and a strip of land that ran up

Speaker:

the mountain behind. And every one of the houses had

Speaker:

this strip of land behind it. So it's a beautiful

Speaker:

old-fashioned way of life, largely gone, I

Speaker:

think, overrun by bigger farms. And it

Speaker:

has to be, you know, for the scale and, yeah, just the economies of modern

Speaker:

farming. Yeah, I've heard a lot of good things about

Speaker:

Scotland. My partner's ex-husband is from there, so she's been

Speaker:

there. She said it's absolutely spectacular. The landscape is

Speaker:

just amazing. And so every time I hear people talk about, you

Speaker:

know, the The Scottish countryside, you know, they come back, you know,

Speaker:

or describing it in terms that just really describe something

Speaker:

that's idyllic and almost fantasy-like, I think, from the ways they're describing

Speaker:

it sometimes. It is the sort of place where if you get the

Speaker:

weather right, it is just phenomenal. It can be very, very

Speaker:

beautiful. It is also a lot

Speaker:

more rugged than perhaps people imagine. I

Speaker:

think one of the things that people in the States don't realize about Europe is

Speaker:

how far north a lot of Europe is, you know. So

Speaker:

Glasgow and Edinburgh are the 2 big cities, they're both

Speaker:

at 55 degrees north. I think the US,

Speaker:

I think, stops at 48 degrees north. Okay. You know, so it's a long

Speaker:

way, it's a, by nature, it's a very different sort of climate.

Speaker:

Yeah. Which is quite interesting, you start talking about indoor farming and

Speaker:

indoor agriculture. Yeah. the different perspectives you have if you're down in

Speaker:

the far south or in the desert or in the far north.

Speaker:

It's a very different set of criteria to what you might

Speaker:

have in Texas or— Yeah,

Speaker:

most definitely. So did growing up there, did that color any of

Speaker:

your decisions when you were in university and

Speaker:

thinking about what to study? Or, you know, take us back a little bit ways.

Speaker:

You don't have to go all the way back with super specifics, but I'm just

Speaker:

curious about your mindset and as we get to present day, what that origin

Speaker:

story looks like. Gosh, there's a

Speaker:

few things from my grandfather's craft. One of them was

Speaker:

one of my cousins who I remember as a young boy,

Speaker:

maybe 5, 6 years old, I was describing to my cousin who was

Speaker:

much older than me, she was probably 30, what I was describing

Speaker:

was the very beautiful patterns you get if you drip oil from an outboard

Speaker:

motor on a boat. into the water and you get these beautiful

Speaker:

rainbow effects. She was absolutely horrified

Speaker:

and was all about the environment and, have you thought about what you're

Speaker:

doing to the fish? And I'm like, no, I'm 5 years old, I'm making pretty

Speaker:

patterns. But that kind of stuck

Speaker:

with me. It was the first person I'd ever heard talk about the

Speaker:

environment and change in the environment. I think the other thing that was

Speaker:

going on back then was My father had been

Speaker:

a major in the war in the British Army in bomb disposal,

Speaker:

and that gave him something of a unique attitude towards

Speaker:

management style. He used to say that when you're in a hole,

Speaker:

the bomb doesn't count the pips. And I don't know if you know about the

Speaker:

pips on an officer's— Oh, the stripes. Yeah. Okay. His

Speaker:

point was, if you're doing a job, it doesn't matter if you're a major or

Speaker:

the lowest rank. the bomb doesn't care, you know, you're a

Speaker:

team, do it together. And so I've tried to live by that,

Speaker:

try not to ask the team to do, to do more than I

Speaker:

would do myself. But that actually— he had a

Speaker:

love of electronics that rubbed off on me,

Speaker:

and I think you've got something of a love of electronic music.

Speaker:

I think we've talked about that in the past. I do, yes, I do. My

Speaker:

first passion is house music, growing up as a

Speaker:

teenager in New York. I took a shine to that

Speaker:

and been to many clubs in New York, and I still have my turntables and

Speaker:

I still play. I played some vinyl this past weekend. Wow. At a friend's comic

Speaker:

book store here in town. So it's always something that I try to get in

Speaker:

as much as possible. I still make DJ mixes on SoundCloud as well.

Speaker:

Nice. So when I was at school in what the—

Speaker:

it would be in the early '80s, I was building analog synthesizers.

Speaker:

So, you know, building keyboards, drum synths were my

Speaker:

particular challenge. I was trying to build drum synthesizers. Okay.

Speaker:

And some friends who were proper musicians, as opposed to people tinkering with the

Speaker:

electronics, started to talk about digital synthesizers. I

Speaker:

was like, how did that work? Digital? That's just numbers.

Speaker:

Learned a little bit more about it, and that led me into going into a

Speaker:

course in digital signal processing and semiconductors.

Speaker:

Which is as far away from power making as you can get, you know. So

Speaker:

my early career started designing chips for mobile phones,

Speaker:

and that was with Motorola, in fact. Motorola, then

Speaker:

Texas Instruments, and then into the world of startups

Speaker:

in the early '90s. Okay. So when I say the early '90s, I'm starting to

Speaker:

feel quite old. That means I've been in startups for 31 years.

Speaker:

That's amazing. And so what were some of the things that were on

Speaker:

top of mind for you? I know as it regards to getting into present

Speaker:

day and the work you're doing with Zaindu, you mentioned your early

Speaker:

influences from family members about thinking about the

Speaker:

environment as you were working in the startup community. What were some of

Speaker:

the other influences that were stemming, were beginning to come on your radar

Speaker:

to start to paint and create this, you know, what maybe your existing

Speaker:

worldview now? I think most of the early

Speaker:

startups I was drawn to because it was cool

Speaker:

technology. You know, things like OLED displays,

Speaker:

so materials for OLED displays, semiconductor materials to improve

Speaker:

the efficiency of LED lighting, mobile television. I would

Speaker:

say I've been in some startups that went very well. I would not say that

Speaker:

mobile television was one of them. Building a TV into your phone

Speaker:

seemed like a great idea at one point. Yeah. Yeah. Some—

Speaker:

you've got the external forces, of course, that influence what's going on.

Speaker:

But that gave me a great view of how the world works,

Speaker:

how the world of startups and investment works.

Speaker:

But most of those were things that when I described them

Speaker:

to my wife or to my family, they would go,

Speaker:

yeah, whatever. They were just cool gadgets that,

Speaker:

you know, the kids might like the idea of. someday, but I

Speaker:

think there's a real difference when you start to talk about what Zyndoo is doing

Speaker:

and people just go, oh, I get that, I see what you're doing, this is

Speaker:

fantastic. Yeah. People can associate with it much better.

Speaker:

And I think that in many ways that transition

Speaker:

from the world of semiconductors came

Speaker:

through a series of— well, they started out looking at things like aircraft

Speaker:

efficiency and really starting to look at what

Speaker:

can we do, not to change the way people have to

Speaker:

live, but to bring things into line, to make

Speaker:

what people need achievable within the bounds of what the world

Speaker:

can provide. Hmm. And so I was actually

Speaker:

introduced to Felipe, the founder of the company, the original founder,

Speaker:

by some friends who said, look, this guy's spinning a company out from the

Speaker:

university. needs some help from somebody who knows about startups.

Speaker:

And every time he opened his mouth, I went, really? Does

Speaker:

it do that? This is so cool!

Speaker:

Yeah. So yes, and that really resonated

Speaker:

with me, the idea of increasing

Speaker:

crop yields and getting rid of chemicals

Speaker:

really without changing anything. You know, there's no chemicals involved,

Speaker:

there's just a little bit of electricity and a little bit of magic, and we

Speaker:

do these amazing things. So it really became one of those ones you just

Speaker:

end up going, I've got to get involved in this. So how much of it

Speaker:

was an education process for you, understanding what

Speaker:

was happening in the controlled environment agriculture space?

Speaker:

And so how much did you need to sort of get up to speed to

Speaker:

get a grasp of really what was being created, what you were getting into?

Speaker:

I've learned a huge amount about controlled

Speaker:

environments. I actually live on a farm. I had that

Speaker:

connection to the Croft back in the early days, so I knew a fair bit.

Speaker:

I knew more than the average man on the street, put it that way. I

Speaker:

had also had quite a lot of exposure to things like LED lighting

Speaker:

and understanding some of the applications of that, particularly in places like

Speaker:

Taiwan and Korea. Okay. With some of their farms. So I've learned

Speaker:

a lot But I think I was already in a place where I was

Speaker:

familiar with the concept and very receptive.

Speaker:

To be honest though, in the very early days, we were not creating

Speaker:

something for controlled environment, for indoor growing. Right. We

Speaker:

were working, and still are working, with the very big seed producers

Speaker:

and saying, if we can make this available

Speaker:

globally for every seed, we've got something which is,

Speaker:

you know, is very significant. What we've

Speaker:

discovered since, of course, is that this business of the controlled

Speaker:

environment, whether it's the vertical farms or the glasshouses, you get

Speaker:

so much benefit from reducing the pathogens. Because pathogens can

Speaker:

only get into a farm in 4 ways, into a vertical farm at least. They

Speaker:

can come in on the people, on the water, on the growing

Speaker:

media, or on the seeds. That's your 4 options.

Speaker:

Okay, so water you can sterilize, that's not a problem. Growing media

Speaker:

again can be sterilized. People, you'd probably

Speaker:

best not sterilize them, but you can probably wrap them up in— I

Speaker:

always think about those, every time you watch those space movies, they,

Speaker:

they go through that chamber that sort of showers them with all sorts of

Speaker:

air or chemicals or something that to sterilize them. And I wonder, I

Speaker:

imagine a lot of that is happening on-site or some of these locations as well.

Speaker:

It is really interesting. The first vertical farms I saw,

Speaker:

people were just wandering around, maybe with a lab coat or something.

Speaker:

And you look at it now and it's much more— to

Speaker:

me, coming out of the semiconductor industry, you're sort of going, you're getting into the

Speaker:

bunny suits and so forth that people are wearing in clean rooms. Yeah.

Speaker:

Some of the big farms are just saying, you are not getting

Speaker:

into our growing rooms, it's just not happening. We've got some nice windows you

Speaker:

can look in, but that's it. And some of those guys

Speaker:

are, you know, they're working up at the 25,000-meter level and

Speaker:

beyond. You know, these things are getting to be really huge. So.

Speaker:

Yeah, I think it's one of those things that people may know,

Speaker:

obviously, in the industry, but people that are new to the industry may not think

Speaker:

on the fact that you can bring in contaminants through those 4

Speaker:

channels. I think it may be news to some folks listening as well. And I

Speaker:

think it's important to understand because one of the I think one of the biggest

Speaker:

selling points when people talk about TEA, indoor farming,

Speaker:

and the benefits of it, obviously in the beginning, a lot of it is touting

Speaker:

the lack of pesticides, the lack of need for controlling

Speaker:

any bugs or contaminants. And I think especially you coming from the semiconductor

Speaker:

industry and this idea of clean rooms, I think it's really understanding and

Speaker:

educating the audience to the

Speaker:

extent as to what's possible from a contaminant perspective in terms of different

Speaker:

sizes, bugs, and— And I'm wondering, you know, based on your

Speaker:

experience, you know, how much of that do you feel is an

Speaker:

education process for some people that may not be aware of what's

Speaker:

possible when it comes to contaminating these rooms? I think it's huge. I have seen

Speaker:

several— I've been working with vertical farms for

Speaker:

4 years and just watching

Speaker:

some of the protocols, the SOPs changing, and what

Speaker:

people are doing. It's certainly been a

Speaker:

wake-up for me. I remember my first trip around a seed factory, a seed

Speaker:

plant, and being asked, you know, don't touch the seeds.

Speaker:

And that was about the limit of it in, you know, for open field farming.

Speaker:

Yeah. And I think if you come from open field into a vertical farm,

Speaker:

you probably don't have that same mindset that comes out of the,

Speaker:

I know, the medical industry or the semiconductor business of keeping it absolutely

Speaker:

clean. So this is, for us, one of the things

Speaker:

that we're bringing to that area is that ability to clean the

Speaker:

seeds before they go in, block off that fourth, the fourth pathogen

Speaker:

vector. And that gets really interesting because, of course,

Speaker:

really you want zero-wash salads. That's the big ambition.

Speaker:

And if somebody, I don't know, they've got a cold and they've got

Speaker:

some pathogens and they Somehow it gets in the

Speaker:

seeds. Before you know it, you've got Listeria or Salmonella or E. coli or

Speaker:

whatever. It's on the seeds. It's inevitably going

Speaker:

to rattle through the farm and out on the salad. And if

Speaker:

we can just stop that getting in there, then, then yes, huge progress.

Speaker:

We talked a little bit about the origins of the name. If you want to

Speaker:

just go through that story, because I think it's contextually helpful for

Speaker:

folks to understand, you know, the mission behind what you're doing at Zaindu.

Speaker:

So I mentioned that our founder, the university professor

Speaker:

behind the technology, is Felipe Iza Perez, and he is

Speaker:

from the Basque part of Spain. So the Basque

Speaker:

region in the north of Spain has its own dialect.

Speaker:

And when we were naming the company, Felipe came up with

Speaker:

this word, Zaindu, and it's based on one of

Speaker:

the Basque words, which just means to care for. And we all went,

Speaker:

actually, that is exactly what we're trying to do. We're trying to care for the

Speaker:

environment. We're trying to do all this good stuff, taking away the

Speaker:

chemicals, improving outcomes for growing. And it

Speaker:

probably goes beyond that with the ultimate vision for the company in terms

Speaker:

of the other approaches, the other things that we can do with this, which extend

Speaker:

on elsewhere into Plasma for Agriculture.

Speaker:

But it's all about caring for the environment, for the plants that we're growing, for

Speaker:

the crops. And that's kind of the ethos that we try and bring

Speaker:

into the business. What was different about this

Speaker:

initiative, Raf, when you think about all the startups

Speaker:

you worked on and all the companies you've worked for and led in the

Speaker:

past? And what was it about Zaindu and Filipe's

Speaker:

mission that attracted you and made you feel like this is something

Speaker:

that you wanted to begin dedicating quite a bit of your time to?

Speaker:

I think, well, when I first met Felipe, I

Speaker:

pretty quickly, I made up my mind about it, but what

Speaker:

cemented it was going home and talking to my wife

Speaker:

about it and her just going, you've got to do that one.

Speaker:

When you start to look at what

Speaker:

Felipe thought we could do, and in that

Speaker:

context of, I suppose, as a family, we've always

Speaker:

been you know, the people who've been pushing to get recycling into our

Speaker:

street and all this kind of thing. You know, we've always

Speaker:

been at that sort of, that sort of end of trying to care for the

Speaker:

environment as much as we can, being very aware of, of the

Speaker:

constraints that the planet has. And when

Speaker:

I described it to Jane, she just went, this is exactly what

Speaker:

you should be doing. You know, this is one that it doesn't matter which of

Speaker:

our friends you explain it to, There are some who in the past, you're talking

Speaker:

about stuff for mobile phones or for planes or whatever, go, oh well,

Speaker:

you know, you shouldn't be flying anywhere, just another gadget.

Speaker:

We've never had that from anybody when we talk about, about

Speaker:

Zaindu. It's just everybody goes, yeah, I get it. And

Speaker:

I think for me, I think there was something of a meeting of

Speaker:

minds with Felipe because I knew a little bit

Speaker:

about farming. I knew a little bit about the electronics. I knew a little bit

Speaker:

about biology and chemistry. Just some people say

Speaker:

CEOs need to know enough to be dangerous, and I think I was probably in

Speaker:

that category. You know, it's that chemistry of the

Speaker:

people as well as of the idea. And so I think that

Speaker:

was a big part. I think that's helped us as we've built the team out

Speaker:

as well. So we've ended up building out a fantastic team.

Speaker:

I think it's quite interesting when you look at a

Speaker:

team and just the way they react, you know, when— because

Speaker:

if you're a small company, you quite often are in a situation where there is

Speaker:

one guy who's responsible for a whole area. And

Speaker:

you can just see when somebody's under pressure, other people will

Speaker:

be making them cups of tea and coffee, going, can I get

Speaker:

that for you? Can I help? Can I do this? Can I do that? Yeah.

Speaker:

Or even, you know, if it's areas where there is

Speaker:

cross-skilling, people stepping in and going, let me do that. So,

Speaker:

and, you know, it's not a 9-to-5

Speaker:

mentality. It's, we're trying to do something here, we're trying to do something amazing.

Speaker:

So if the work's done at half past 4, people will be disappearing.

Speaker:

On the other hand, if the work's not done at half past 5 or half

Speaker:

past 6 or half past 9, people are not disappearing, people are getting on.

Speaker:

And, you know, I really like that. It's a very fine balance between putting pressure

Speaker:

on people people to deliver against a milestone or a deadline or whatever?

Speaker:

And are we creating an environment where they feel that they're under pressure,

Speaker:

even though you don't think you're putting them under pressure? I like to think that

Speaker:

it's because they love what they're doing. They see where we're going.

Speaker:

You know, I think it's— Yeah, I think that's a testament to the quality of

Speaker:

leadership as well, because when you see companies that do it well and do it

Speaker:

successfully, it's this really fine balance of

Speaker:

ensuring that everyone is bought into the mission. And probably that's something that needs

Speaker:

to happen It's easier if you're hiring the person, probably a bit more

Speaker:

challenging if you're stepping into an organization where there's already people there and they've

Speaker:

had a previous leadership and you've got to now convince them that this is the

Speaker:

new way of doing things. But I think feeling that

Speaker:

everyone's moving towards the same mission, the same goal, for the same

Speaker:

reason, I think helps to keep people bought in. And during those

Speaker:

times and those stretches when things can get tough or nights or afternoons can get

Speaker:

long, I think feeling like they're not being put out or being

Speaker:

asked to go above and beyond for no reason. I think everyone's bought in,

Speaker:

and I think it helps with the culture there. Is this leadership style

Speaker:

something that you've learned over the years, or it's something

Speaker:

that someone has inspired— your previous, you know, bosses have

Speaker:

inspired you to adopt? I think it's probably a

Speaker:

little bit of many things. I mentioned my father and

Speaker:

his view of Bobbin's attitude to rank.

Speaker:

And also an upbringing within

Speaker:

Motorola and Texas Instruments, who are fantastic training

Speaker:

grounds. I mean, people in semiconductors used to joke that Texas

Speaker:

Instruments, or TI— TI stands for Training Institute—

Speaker:

because they were fantastic. You were put on

Speaker:

so many courses, management style, commercial courses.

Speaker:

They really invested in their people back in those days. And I can't speak for

Speaker:

what it's like now, but they really helped a lot. I think there are

Speaker:

several bosses along the way, some

Speaker:

who would completely fail today's politically correctness

Speaker:

tests. That's true. But yeah, some

Speaker:

real characters that you just learn so much from.

Speaker:

And yeah, one character in particular I'm thinking of who's

Speaker:

sadly no longer with us, But he was just brilliant at knowing when

Speaker:

to push, what to say, what offensive thing

Speaker:

to say that people would probably just about forgive him

Speaker:

for, but which absolutely made him the center of

Speaker:

attention so he could make whatever point he wanted to make. And he was absolutely

Speaker:

brilliant. So yes, I've been very lucky with the

Speaker:

people I've been able to learn from. And,

Speaker:

and then also very lucky In the people that I've had working for me,

Speaker:

in that sometimes you see what they're doing with their teams and go,

Speaker:

that works. So

Speaker:

talk a little bit about managing the company through

Speaker:

trying times. I see that the company started in 2019, so naturally you had to

Speaker:

make it through what the whole world experienced in terms of

Speaker:

COVID And this is— that's when our show started in March of 2020. So

Speaker:

I'm curious, what was the challenges you were experiencing

Speaker:

as a leader and how you managed through that to present day?

Speaker:

Yeah, COVID was a real difficult time.

Speaker:

Initially, there was the whole shock of the world is just

Speaker:

ending. And I think the first thing that we did was

Speaker:

gather our family around and try to

Speaker:

make sure that the rest of the team had done the same. Of course, we

Speaker:

were a very small team at that point. only 3 or 4 people, in fact

Speaker:

4 including Felipe. And so we gathered the family

Speaker:

around and then went, well, actually we can

Speaker:

continue working as a team. We've got all

Speaker:

these fancy remote tools, you know, with Teams and Zoom and so

Speaker:

forth. We can do this. And so even with the—

Speaker:

well, it wasn't just social distancing, was it? It was quarantine where you're sort of

Speaker:

locked in your house. We were able to— we

Speaker:

got a machine back, actually into Felipe's garage.

Speaker:

He was able to be running it, developing things, passing

Speaker:

stuff out to one of the guys working on software. I was ending up doing

Speaker:

things on algorithms and so forth. It was, in a way,

Speaker:

we were on teams continuously,

Speaker:

and I think that was very important to keep giving each other

Speaker:

support, and a continuous

Speaker:

interaction with other humans. So that worked pretty well. And then, of course,

Speaker:

at the first point that the quarantine was relaxed,

Speaker:

we had to talk about how we would continue to work with social distancing.

Speaker:

Well, at that point, the company was based in the university's innovation center,

Speaker:

and we'd started in one unit, and then we needed a second

Speaker:

unit, and these were very small offices. Yeah. And then we needed a third one,

Speaker:

and there were 3 employees. And so

Speaker:

the university said, well, if we're going to let you back in the building, how

Speaker:

are you going to handle social distancing? And we went, he's in that

Speaker:

unit, I'm in that one, we'll shut the doors.

Speaker:

Yeah. So yes, we started to get

Speaker:

back in that way. We did make a lot of

Speaker:

progress. We would have made a lot more progress just at the stage that we

Speaker:

were at A lot of relationships that we had

Speaker:

were with companies in the Netherlands. We couldn't ship things in or out.

Speaker:

We couldn't get access to things. And obviously things like the

Speaker:

biology lab, it's a Class 2 biology lab. We need

Speaker:

that for testing things like pathogens in seeds, testing

Speaker:

germination rates and so forth. We couldn't get access to that,

Speaker:

but we could get access to the basic physics of what the machine was

Speaker:

doing and And evolved it a lot through that period.

Speaker:

A lot of the sensors and control, I mean,

Speaker:

they've evolved further since then, but a lot of the first

Speaker:

prototypes were put together through that phase. So we

Speaker:

achieved a lot, but it really caused a

Speaker:

lot of issues for us. Having said that, we then had to

Speaker:

cope with Brexit, so that's all part of the fun and games. All the

Speaker:

different things that come, you your way as a leader, obstacles. And I think it's

Speaker:

a testament to making you stronger, the fact that you can get through those,

Speaker:

the fact that you can survive. And I think a lot of companies realized, you

Speaker:

know, there was limits to what you thought you could do pre-Brexit, pre-COVID.

Speaker:

And then I think the companies that survived and came out stronger as a result

Speaker:

of figuring out ways to work through these situations

Speaker:

ended up being more resilient. And I think it's made them all stronger as a

Speaker:

company. And I'm sure that you would relate to that as well. Yes, you

Speaker:

hear some amazing stories from a lot of the people you've had

Speaker:

on your shows about how the companies have come out and done

Speaker:

amazing things. I think one of the things that is very

Speaker:

different is that people are much more relaxed. I think

Speaker:

if you look at dress codes, they've become more relaxed. I

Speaker:

can't remember the last time I wore a tie, and getting

Speaker:

calls from HMRC. So HMRC is the UK tax

Speaker:

office, so it's the IRS. And chatting to a lady

Speaker:

at HMRC and she said, oh, I'm terribly sorry, that's my baby crying in the

Speaker:

background. That would not have happened pre-COVID.

Speaker:

It's just normal now. It's normal. Yes.

Speaker:

And I think it's great too, especially coming from a podcast perspective. With my first

Speaker:

show, Podcast Junkies, which I've started since 2014,

Speaker:

300 interviews, I mean, I've had everything from a cat or a

Speaker:

dog jumping into the guest's lap, doors opening,

Speaker:

delivery trucks arriving, doors knocked on, doorbells going

Speaker:

off. And I leave it all in because it's a podcast where we talk to

Speaker:

other podcasters and it's nice to see warts and all.

Speaker:

No one's really— everyone's aiming for NPR status or BBC status, but I

Speaker:

think they know that really realistically it's not happening.

Speaker:

But I think it also— endears us all and makes us all closer to each

Speaker:

other. And I think we all realize, hey, we're all doing the best we can

Speaker:

given our circumstances. And I think when we let some of

Speaker:

those cracks come through, I think it helps us all connect to

Speaker:

each other on a more human level, which I really love. So for the

Speaker:

benefit of people who are not familiar with exactly what Zindu does, I

Speaker:

know there's been words thrown around in some of the press releases and some of

Speaker:

the talks that you've been giving about Plasma technology, which sounds really fancy,

Speaker:

but I think for the benefits of this audience, if you could give an overview

Speaker:

of what you're currently working on and who an ideal

Speaker:

customer would be and some of the current projects you're working on. Sure.

Speaker:

So going back to the founding of the company, what

Speaker:

Felipe was describing to me was using

Speaker:

plasma to create an environment around seeds.

Speaker:

Which would have a big effect on the seed's

Speaker:

health. What the Plasma is actually doing, what we're

Speaker:

proving in so many of the farms now, is something like a

Speaker:

20% uplift in crop yield on things like leafy

Speaker:

greens. It's very easy to quantify on things like

Speaker:

microgreens, leafy greens and so forth, because

Speaker:

it's a fairly quick crop cycle and you see results quickly.

Speaker:

So what we're doing is using a little bit of electricity to

Speaker:

create plasma in air, or actually convert the air into a

Speaker:

plasma. And maybe explaining what plasma is is not

Speaker:

a bad place to start. So there's— matter has

Speaker:

4 states. At school, most of us were taught about 3 of them.

Speaker:

There's solid. So if you imagine, let's start with a block of ice. The block

Speaker:

of ice is solid. It does not behave Like

Speaker:

water, and you can see this if you put a block of ice into a

Speaker:

microwave, it doesn't melt. And the

Speaker:

reason it doesn't melt is because a microwave works by moving the molecules around,

Speaker:

and the block of ice, the molecules are locked solid, they're not going

Speaker:

to move. So somehow you're going to put some energy into that ice and

Speaker:

it turns into water, and now the microwave does have an effect on it.

Speaker:

You put more energy into it, it turns into steam, it's a gas now. Yeah.

Speaker:

You put even more energy into it and it turns into a plasma. So

Speaker:

plasma is this 4th state of matter, it's a high-energy state, and

Speaker:

instead of having these very solid bonds that the ice had,

Speaker:

they became looser with the water, looser again with the gas, and we

Speaker:

actually start to split up the, the molecules so they become

Speaker:

separate ions. And at that point, a lot of

Speaker:

interesting things happen. So we have things like atomic oxygen.

Speaker:

and atomic nitrogen in this mix in the plasma. So we're not

Speaker:

creating any chemicals, we're just rearranging the

Speaker:

molecules in the air. Okay. The air, we talk then

Speaker:

about activated air. The seeds are in this activated air.

Speaker:

It creates fissures in the coating of the seed.

Speaker:

So this allows moisture in, which helps the seed to germinate

Speaker:

quicker. It actually makes the seed germinate more

Speaker:

consistently, so growers will talk about synchronizing a crop.

Speaker:

Synchronizing a crop is a strange thing. If you're a home grower, it's your worst

Speaker:

nightmare. You do not want every lettuce you ever planted to be ready

Speaker:

for picking on Wednesday. You'd be quite happy if one was Tuesday, one was

Speaker:

Thursday, and one was sometime next week. Yeah. But for a commercial grower,

Speaker:

synchronizing is a very important factor, and we get that through creating

Speaker:

these microfissures. At the same time, we're

Speaker:

creating microfissures in any pathogens that might be in there. And you could

Speaker:

imagine a microfissure that a seed goes, oh,

Speaker:

that's helpful, goes right through a bacteria or a fungal spore,

Speaker:

for example. So you get a massive reduction in the pathogen

Speaker:

load on the seed. So you now have a seed which has much lower pathogen

Speaker:

load on it. It has microfissures which help it

Speaker:

germinate more quickly. The waxy coat on a lot of the

Speaker:

seeds is either thinned or removed. And the

Speaker:

final thing that we do is we fine-tune a hormonal

Speaker:

response in the seed which helps it throw

Speaker:

off its conservative nature. It's instead of

Speaker:

going, oh no, you know, I should hold myself back just in case there's a

Speaker:

bit of a drought or whatever. Yeah. It's going into an indoor farm. There is

Speaker:

not going to be another drought. So you can use the hormones

Speaker:

to adapt the way the seed is going to perform. What

Speaker:

we try and do is throw them to tweak the hormones so it

Speaker:

throws a bigger, better root system very early. And of course,

Speaker:

bigger, better root system means bigger, better seedling, which drives

Speaker:

this huge increase in the seedling growth. So you get a

Speaker:

seedling which germinated perhaps 2 or

Speaker:

3 days quicker than it would have done before, and which then

Speaker:

grows 20% faster. And so that is

Speaker:

you can imagine, proving very exciting. In some ways,

Speaker:

I wish it was less than 20% because all you get is— well, you

Speaker:

usually get an expletive from a farmer when you tell them about it,

Speaker:

and then it's show me. Of course. So of course, what we're looking for is

Speaker:

the guys who we get these things out on a sort of a

Speaker:

try-before-you-buy trial, put them into a vertical farm or a

Speaker:

glasshouse or whatever, and that side of things is

Speaker:

going along really nicely. It does take

Speaker:

some convincing to get people across the line initially because it

Speaker:

looks like snake oil. A lot of people are talking about the

Speaker:

confidentiality, this secrecy that goes on in the indoor

Speaker:

farming community, and it's a real

Speaker:

pain, it's a real aggravation for me because the

Speaker:

big guys just don't want to talk about it. They're going, look, this is an

Speaker:

unfair advantage. why do we tell anybody else about it?

Speaker:

Yeah, so we're starting to get a few out that are opening up a little

Speaker:

bit, but generally the proof points that we have end

Speaker:

up being some of the big public organizations, people like

Speaker:

NIAB in the UK. NIAB is the National Institute for Agriculture and

Speaker:

Botany, so they've run a bunch of trials. So seeing

Speaker:

basil at +30%, wow, they were pretty chuffed with

Speaker:

that, pretty pleased. So yeah, it's— that's what we

Speaker:

do. We make better plants. Do you find

Speaker:

that it's applicable for certain seeds, for certain

Speaker:

crops, for certain size farms? Is there a sweet spot or is

Speaker:

it one of these things that, you know, with enough time and enough proper

Speaker:

environment setup, it's almost anyone can benefit from it? We

Speaker:

have vanilla protocols on the machines

Speaker:

and So generally, when we come across a new

Speaker:

plant variety, the team have enough

Speaker:

experience to look at the seed and go, try that.

Speaker:

And I think almost without exception, their first

Speaker:

attempt will give good results. And we've done

Speaker:

that on over 90 varieties now, so it's, it's

Speaker:

pretty well proven. What we then do is some fine-tuning.

Speaker:

And the fine-tuning gets to be really interesting because we

Speaker:

fine-tune for the crop but also for the growing system.

Speaker:

Because there is a huge difference between the

Speaker:

sorts of parameters that are important in

Speaker:

aquaponics, hydroponics, aeroponics,

Speaker:

fogponics I was hearing about. Yeah, Alberto Aguilar from

Speaker:

Plantaform, shout out to him. Yes, that was my drive home yesterday.

Speaker:

So we optimize the seeds to that. The machines themselves are actually

Speaker:

cloud-connected, so we can work with a grower to

Speaker:

optimize. But yet it is applicable to

Speaker:

pretty much any seed. We, for example, the vast

Speaker:

majority of what we do with vertical farms is leafy greens of

Speaker:

some description, herbs. Yeah. Saying that, we have a

Speaker:

series of vertical farms who are working with us on trees. Where

Speaker:

with some of the tree varieties, we've taken germination rate from, I

Speaker:

think it was somewhere in the 20% range, 20 to 30%,

Speaker:

taking it up to 80 to 90%, which is

Speaker:

significant. And yeah, I'm

Speaker:

sure there are things out there that we can't do, but we haven't found them

Speaker:

yet. And is it applicable specifically at the

Speaker:

seed level in terms of the production cycle, or is there other

Speaker:

aspects of it where The Plasma Technology can be

Speaker:

applied post-seed sprouting, seedlings,

Speaker:

anywhere along that process? The systems that we're building are all

Speaker:

about the seed health. There are various other companies

Speaker:

who are looking at things like Plasma activated water, which is great as

Speaker:

disinfectant, but also for fertigation. So that's an interesting

Speaker:

area as well. The difference there is that,

Speaker:

We've focused completely on seeds and developing the protocols and so forth

Speaker:

to have that speciality in that sector. Seeds,

Speaker:

actually, there is huge value in having a dry treatment for seeds

Speaker:

because you want to go straight into an automatic seeding machine, and

Speaker:

wet seeds don't work in seeding machines. Some

Speaker:

seeds like basil, if you get them wet, that's the end of the game anyway.

Speaker:

They just turn into a biscuit. So yeah, it's So, the Plasma

Speaker:

can be applied in many areas. We actually have quite a

Speaker:

series of longer-term plans for other areas we can

Speaker:

bring Plasma into agriculture. It's just a case of, at the moment,

Speaker:

focus on one thing and do it right. And I think that's one of the

Speaker:

lessons I've had from startups, is the number one

Speaker:

thing you have to do in a startup is focus. There's so many exciting things

Speaker:

you can do, but just focus and do one right. Yeah, shiny

Speaker:

object syndrome is definitely something that a lot of founders

Speaker:

deal with on a regular basis. I'm curious, I saw that you're speaking

Speaker:

at the Indoor AgTech NYC. Is there a talk scheduled as well,

Speaker:

or? Not. Okay. We've had a small

Speaker:

family crisis, and so I'm not speaking at it in

Speaker:

New York. However, Alberto Campanaro, Dr.

Speaker:

Campanaro, who is our head of plant science, is taking that slot.

Speaker:

Okay. And he will be absolutely brilliant. He is a passionate

Speaker:

Italian. He'll wave his arms around a lot. He

Speaker:

really knows his stuff on the plant science. So, you

Speaker:

know, if you had me, you'd have one perspective. I'd talk more about the plasma

Speaker:

physics. If you get him, you get a lot more on the plants.

Speaker:

So it should be good. I'm just sorry I'm missing out. Are you going?

Speaker:

Yeah, I'm headed there. This recording will likely come out after the

Speaker:

conference. But it's Wednesday, it's actually June 27th,

Speaker:

2023, so I'm leaving tomorrow morning, heading on a flight to New

Speaker:

York, which is my hometown. So I'm excited to get back there for a couple

Speaker:

of days. I'll be there through the weekend and to see my parents as well,

Speaker:

who live just north of the city as well. Nice. So, but I'll make sure

Speaker:

to look out for anyone who's there from the company and chatting up. The

Speaker:

2 days I'm sure will go fast, and I'll have a recap in a future

Speaker:

podcast episode of everything I learned and all the new CEOs and founders I've met,

Speaker:

who I'm sure I'll have a new list, as tends to

Speaker:

happen at these conferences. So Ralph, I also want to

Speaker:

ask a question that's common, and as a regular listener, you might know what's

Speaker:

coming, but what is a tough question you've had to ask yourself recently? Oh

Speaker:

gosh. I think the toughest question that I've been

Speaker:

struggling with relates to the pricing model for

Speaker:

what we're doing. Now, it might sound

Speaker:

very money-oriented, but actually what we're doing at

Speaker:

the moment is a flat-rate subscription effectively for

Speaker:

the machines. And the bigger machines, the bigger the

Speaker:

subscription. But there's a lot of the farms where

Speaker:

if it's a big farm, they're getting an amazing deal. If it's a

Speaker:

mid-sized farm, it's probably about right. And then the small

Speaker:

guys, you know, the guys who are in containers, Yeah. Doesn't

Speaker:

make sense at this stage. And that's something that I'm

Speaker:

slightly struggling with, is how we move that one

Speaker:

forwards. It's just really— and I think the answer

Speaker:

lies with the cloud connection of being

Speaker:

able to do a sort of a pay-per-use type of thing,

Speaker:

trying to get it to a point where it becomes more

Speaker:

accessible. I think to do that, we have to drive some of the costs out

Speaker:

of the machine. You can imagine these first machines are probably

Speaker:

over-engineered. We can probably get a bunch of the cost out and bring it down.

Speaker:

But at this point, for the container farms, these things that we've been suggesting to

Speaker:

people are, you know, there's a few farms in an area, let's

Speaker:

set up some sort of cooperative or collaborate with a cooperative to

Speaker:

get something in there. It's interesting in that the

Speaker:

ag chem market use differential pricing.

Speaker:

So if you apply some chemicals to wheat, you get it for some

Speaker:

pennies per liter. If you apply that same chemical to tomatoes,

Speaker:

it is many orders of magnitude more expensive. Interesting.

Speaker:

So there is sort of a parallel model perhaps of

Speaker:

going, yes, if you're using a machine like that, then you pay a little bit

Speaker:

more or a little bit less. Maybe we can have a snooze mode for the

Speaker:

guys who have seasonal planting.

Speaker:

So I think that's been one of my thorniest

Speaker:

things that I'm wrestling with at the moment. Yeah, it seems like it's

Speaker:

something that it wouldn't be a one-size-fits-all, and especially for some of these

Speaker:

smaller farms, one-shipping-container farms, folks just getting

Speaker:

started, dipping their toe in the water, you know, it'd be nice to see if

Speaker:

that they could benefit from a technology like this, which I think, you know, in

Speaker:

the past might have been something that would be cost prohibitive for them. And I

Speaker:

think to see those those improvements

Speaker:

in growth time and yields? I think anyone who's in this space is obviously looking

Speaker:

to, you know, if we can— a couple of days could mean a big deal

Speaker:

for some of these smaller farms, especially shaving off the time from those

Speaker:

cycles. Some of the— oh, I keep calling them micro

Speaker:

herbs, but the microgreens, you know, where they're only growing

Speaker:

for 10 days, if you can shorten that cycle by 2 days, forget

Speaker:

about how big the plant's grown, you know, that's phenomenal.

Speaker:

So yeah, it's— for me, it's a real big thing. I want to

Speaker:

be able to make a difference. And I think a lot of your guests have

Speaker:

talked about, you know, food deserts, local food supply, and

Speaker:

so forth. Well, if we're working with the really big guys,

Speaker:

which we are at the moment, that's great, but it's not going

Speaker:

to address some of those very local suppliers. We'll have to do a little bit

Speaker:

on the pricing machine the accessibility model. And I

Speaker:

think we've got the tools there to do it. It's just, it's something

Speaker:

that we will layer on as we build the product range and the

Speaker:

company. Yeah, that makes a lot of sense. So as you

Speaker:

know, I leave some time at the end of these conversations for any thoughts you

Speaker:

have for your peers and your colleagues in the industry. And I think it

Speaker:

helps to keep a dialogue going, and it helps to just have

Speaker:

my guests talk about what's on their mind in a way that they feel like

Speaker:

they can share it in some sort of community forum or whatever

Speaker:

space we're creating here. But I've been glad to have—

Speaker:

giving my guests this opportunity. We've been hearing some interesting thoughts, and

Speaker:

I'm just curious about what your thoughts are as we get ready to head

Speaker:

into this conference. And I'll be connecting to a lot of your peers and

Speaker:

colleagues in the space. Any thoughts that you have? Yeah, I think

Speaker:

at the moment, There's a huge herd

Speaker:

mentality that's going on in the vertical farming space.

Speaker:

There's been something of an assumption of one

Speaker:

size fits all, that just because one farm isn't going

Speaker:

well, that's the end of the vertical farming technology.

Speaker:

I think what people have to do is— oh, it's actually interesting, that throws me

Speaker:

back to semiconductor days. So I shared

Speaker:

a flight back from— oh, I'm going to have to say California

Speaker:

because I can't remember if it was the top end or the bottom end. But

Speaker:

I was with Jamie Urquhart, who is one of the founders of ARM.

Speaker:

ARM, the microprocessor company, which is in your mobile phone and

Speaker:

car and everything else on the planet. So Jamie's an interesting

Speaker:

character, and he had just joined a venture capital

Speaker:

fund. And I was teasing him a little bit, and

Speaker:

he said, you know what? Actually, before I joined a venture capital

Speaker:

fund, I thought I'd be different. I thought I'd go in there. I thought I'd

Speaker:

be the voice of reason. And now I realize I'm buying along with the

Speaker:

rest of them. It's just one of the sheep in the

Speaker:

herd. Yeah. And I think there's a danger of that that's going

Speaker:

on. I think we all look at the news flow

Speaker:

and we assume that it's,

Speaker:

you know, horrific. And yet, when you actually talk to people out there,

Speaker:

that's not really what's going on. It's what's in the news.

Speaker:

And if you just look at what's in the news,

Speaker:

you wouldn't go out for fear of being stabbed or shot or whatever. You'd stay

Speaker:

at home. I think people have to stop looking

Speaker:

at things. You know, this is a horrible thing to say to an American. Oh,

Speaker:

you're not an American really originally, are you? No, I wasn't born here,

Speaker:

but yeah. Now I would consider myself an American, yes. Yeah, okay.

Speaker:

So one of the things that struck me about the States is this

Speaker:

fascinating fact came out just recently that a couple of years

Speaker:

back there was a survey done that says 85% of Americans believe that America

Speaker:

is the best country in the world. And I think that, that's great.

Speaker:

The next statistic that came out was 40% of Americans have a

Speaker:

passport. And you go, 45% of

Speaker:

Americans think it's the best country in the world, they've never been to any other

Speaker:

country. Yeah. And I think there's a little bit of that

Speaker:

going on in the indoor growing market, of people just listening to

Speaker:

what people are saying, getting brainwashed. I'm not saying that

Speaker:

America isn't the greatest country, I'm just saying that, you know,

Speaker:

we should all be making decisions based on what

Speaker:

facts we can get our hands on, not what perceptions that we have, because

Speaker:

the world is different. And you see the stories of the guys up in

Speaker:

Finland who are making I don't know if I can say

Speaker:

Lusgarta. Those guys are doing

Speaker:

great with lettuce. People say it's not possible to grow lettuce in a vertical farm

Speaker:

and make money. Well, yes it is. And of course in the Middle

Speaker:

East also, you know, I think it's important to draw

Speaker:

on that. I think another aspect is thinking

Speaker:

about what really is the difference between a greenhouse and a vertical

Speaker:

farm. You hear a lot of People talking about,

Speaker:

you know, all this money that's been thrown into vertical farming, and if only greenhouses

Speaker:

had access to it, or the glasshouse industry. But actually,

Speaker:

if they're developing LEDs and HVAC and so forth,

Speaker:

all of these things are just as applicable. So it's a rising tide

Speaker:

that lifts all boats. And, you know, there's the real sort of hybrid

Speaker:

model there as well. So yeah, it's definitely

Speaker:

great to see more of the greenhouse manufacturers who've had

Speaker:

such a head start. And they talk about how much production comes out of a

Speaker:

country as small as Holland, you know, in terms of like the greenhouse

Speaker:

production and all the technology and all the experience they've had, decades

Speaker:

of innovation happening. And to see that coming into the vertical farming space,

Speaker:

to see where there's hybrid models that are being applied, I think that makes a

Speaker:

lot of sense. And I think people— there's always opportunities to learn from

Speaker:

other industries that have I had a leg up and been doing this for a

Speaker:

while. So I think to your point, it's helpful to see everyone

Speaker:

taking a breather and also seeing that there's a lot to learn from each other,

Speaker:

and there's no one company that has it all figured out.

Speaker:

And I think this idea of not knocking a system until you've had

Speaker:

the opportunity to try it or try it in your environment, and it may not

Speaker:

work for your environment, it may not work for your farm, but that doesn't mean

Speaker:

it's not a technology that could be suitable for other environments. And I think it's

Speaker:

just just having this open approach to a guest.

Speaker:

Everyone's consistently saying the same thing, you know, it's still early days within

Speaker:

specifically vertical farming, and I think it's helpful for us to have, you know, an

Speaker:

open attitude towards, you know, working together and seeing how

Speaker:

the things that are— that we're coming across, the companies, the new technologies, can be

Speaker:

applicable and beneficial for everyone. So I'm glad that you're

Speaker:

echoing things that have been said on this show as well, so I appreciate that.

Speaker:

Yes. So any closing thoughts as you think about the future and where you're headed?

Speaker:

Just that we are heading into some very exciting times. I think

Speaker:

we have, as an industry, we've got to get this right.

Speaker:

I think whether it's glasshouse, vertical farms, or whatever, we've

Speaker:

got to move the agricultural output forwards.

Speaker:

And I think we're a very, very big part of that story. I think

Speaker:

this staggering number is this story of agriculture using 70% of the

Speaker:

Earth's water, and now we're going to increase agriculture by 50%,

Speaker:

and you're going, well, that means there's not gonna be any Perrier,

Speaker:

doesn't it? The math on that does not work out. Yeah,

Speaker:

so we've got to do something about it, and I think

Speaker:

you're very much in the center of that with this podcast, with this show,

Speaker:

helping pull together the— pull together the community. I think that's

Speaker:

fantastic, and Yeah. So I think you were in the right place at the right

Speaker:

time as well. Well, thanks again to Mickey

Speaker:

for connecting us and also just helping me discover all

Speaker:

these new companies, all these new founders and CEOs with these amazing

Speaker:

stories. And I think all these— I'm learning with every episode, with every

Speaker:

conversation. And I know my listeners are just getting just as excited at the

Speaker:

potential for what's happening. So again, we keep saying it on repeat, but it's

Speaker:

still early days and there's so many exciting opportunities that are happening in this space.

Speaker:

And I'm Grateful to you for sharing your story, your inspiring

Speaker:

origin story as well, because of all the different ways to come into this

Speaker:

space. You know, there's no one way, and I think people continue to get

Speaker:

inspired on all the different paths that people are taking to

Speaker:

contribute to what we're all working towards. So thanks again for coming on and sharing

Speaker:

your story. It's been an absolute pleasure, Hari. Thank you for the opportunity.

Speaker:

And so Zayndu, zayndu.com. Anywhere else you

Speaker:

want to send folks to? connect with you? I think that would be the main

Speaker:

one, the best place to get us. Yeah, we'll make sure all the links are

Speaker:

in the show notes as well. Thanks for your time, Ralph. Thank you, Harry.

Speaker:

$680 million poured into precision ag last year.

Speaker:

Autonomous weeding robots dominated, and John Deere made 2 acquisitions in

Speaker:

3 months. A food company, not an equipment maker, bought a

Speaker:

robotics startup to protect its own supply chain. The deals are

Speaker:

accelerating, the money is moving, and the winners are already separating from the

Speaker:

pack. If you're investing, building, or buying in this space,

Speaker:

you need the full picture before your competitors get it. The 2025
