Why do 65% of startups fail?

It’s not a lack of funding. It’s not product-market fit. Matt Jones, psychologist, coach, and author of The Co-Founder Effect, says the number one killer of startups is co-founder conflict.

In this episode of The Startup CEO Show, I sit down with Matt to unpack why co-founder relationships make or break companies and what founders can do to prevent disaster. We explore the hidden reasons co-founders clash, why alignment and values matter more than strategy or capital, and the practical frameworks Matt uses to save partnerships before they implode.

Whether you’re choosing a co-founder, scaling through Series B, or already feeling the strain, you’ll learn how to protect your partnership and your company’s future.
