Ikkjin Ahn is the co-founder and CEO of Moloco, the machine learning-powered advertising platform he built from scratch after spotting a gap at Google: 90% of apps in the Play Store weren't making money. Armed with insights from building YouTube's monetization engine, he launched Moloco in 2013 to democratize access to the kind of AI that only tech giants could afford. Thirteen years later, the company is a $1.5B+ unicorn with 700+ employees across 12 offices, over $200M in annual revenue, and profitable for five consecutive years - a rare combination in Silicon Valley. As of early 2026, Moloco is weighing an IPO.
