Shownotes

Today’s guest is Loren Grossman, Global Chief Strategy Officer of the ‘Solutions Group’ within Publicis Groupe – so he’s right at the centre of how the agency world is evolving.

Loren describes a ‘golden age’ of impact, explaining how Publicis has built a future-facing model that goes far beyond marketing communications. From bold acquisitions like Epsilon and Sapient, to their ‘Power of One’ approach that brings every capability together, he shares how the group has worked hard to make integration really work – and how that’s fuelled their relentless new-business success with the likes of Coke and Mars. 

Packed with insights on leadership, culture and the real opportunities in AI and data, this conversation paints a truly optimistic picture of where agencies are headed and how to stay relevant in a rapidly changing market.
