Jim Payne is the co-founder and CEO of CloudX, an AI-native mobile advertising platform that treats ad monetization like code and hands the busywork to autonomous agents. An MIT-trained computer scientist and former Google product manager, he built MoPub (sold to Twitter in 2013) and MAX (acquired by AppLovin), two products that shaped how apps make money. After years investing through his firm Breakpoint Capital, he returned to building in 2025, launching CloudX with a $30M Series A led by Addition to rewire the mobile ad stack for the AI era.
CloudX is an AI-native ad monetization platform for mobile publishers, built by the founders of MoPub and MAX. It rebuilds the programmatic supply-side stack so autonomous AI agents - not manual ops teams - can run auctions, manage price floors, and optimize revenue, with auction integrity verified inside Trusted Execution Environments. The company launched out of stealth in November 2025 with a $30M Series A led by Addition.
