In Part 1 of this episode, global commercial leader Matt Ring charts his journey from selling TV ads at Sky to building enablement and go‑to‑market at Deliveroo. He shares the painful moment when a long‑awaited product launch flopped because no one was prepared for the change – not sales, not restaurants. Matt explains how this led to a deceptively simple “T‑shirt sizing” framework that helped Deliveroo finally coordinate product, ops, and frontline teams around change.
