Jim Payne
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.
Herman Yang
Herman Yang is the CEO and co-founder of Upscale AI, an AI-native platform that lets e-commerce brands create, run, and optimize performance TV ads on streaming channels. A Stanford CS grad with an MBA from Harvard Business School, Yang spent over a decade reshaping mobile advertising at AdMob (acquired by Google) and MoPub (acquired by Twitter, then AppLovin), before stints at Facet Data, Chatgrid, and Moloco. In May 2025, he emerged from stealth with $5.5M in seed funding - backed by Nvidia Ventures, M12, Eniac, and others - to democratize what was once a $100K-minimum medium: streaming TV ads, rebuilt from scratch for performance marketers.
