EP31 Jim Payne

On this episode of the Human Unicorn Podcast, we sit down with Jim Payne — founder and former CEO of MoPub, the pioneering mobile ad exchange acquired by X (formerly Twitter) before its IPO, and founder of CloudX. Jim shares the story behind building one of the earliest large-scale mobile advertising marketplaces, helping shape the infrastructure of the modern mobile internet during the smartphone boom. We dive into the rise of programmatic advertising, the evolution of ad tech from AdMob to real-time bidding, and what founders often misunderstand about timing, distribution, and market shifts. The conversation also explores Jim’s latest venture, CloudX, and his perspective on the future intersection of cloud infrastructure, AI, and digital platforms. From scaling startups through hypergrowth to navigating acquisitions and platform transitions, Jim offers a rare operator’s perspective from inside some of the most transformative moments in tech.
