AppLovin CEO Adam Foroughi built a $50B mobile gaming ad platform without VC funding, surviving a 92% stock collapse by becoming the company's best investor. His lean team quietly outperforms Meta and Google in e-commerce ads by treating advertising as machine learning 1.0—the foundational technology powering AI today. AppLovin operates in a $50 billion annual mobile gaming ad market where deep learning models predict user intent and drive discovery, not just search completion, creating genuine economic expansion.
