AppLovin

AppLovin is a Palo Alto-based advertising technology company that runs an AI-driven marketplace connecting app advertisers with the users most likely to engage with them. Founded in 2011, it grew from a mobile-gaming ad network into an S&P 500 company by building AXON, a machine-learning engine that matches advertiser demand to publisher supply in real time. After selling its own games portfolio in 2025, AppLovin now focuses almost entirely on high-margin advertising software, expanding beyond gaming into e-commerce and connected TV.
