The Diary of a CEO has become the world’s second biggest podcast and one of the fastest-growing shows globally by building a culture centred around experimentation, audience understanding and constant evolution.

 

This session will explore how the teams behind The Diary of a CEO and Flightcast think about growth in an increasingly competitive creator landscape. The conversation will unpack how leading podcast teams use experimentation, performance insight and audience data to make smarter creative and commercial decisions, while continuing to build content that resonates at scale.

 

The panel will also discuss the role failure plays in innovation, why experimentation has become a competitive advantage in modern media, and how the next generation of creator tools and audience intelligence could reshape podcast growth in the years ahead.

 

Joining the session are Rox, Co-Founder & CEO alongside Steven Bartlett at Flightcast, and Grace Miller, Head of Experimentation and Failure for the Diary of a CEO, moderated by Sally King-Carter, Head of Global Partner Management at Flightstory. Together, the panel will share practical insights and behind-the-scenes learnings from helping build one of the most influential creator-led media ecosystems in the world.
