AppLovin

One of the top two mobile advertising platforms globally, competing directly with Unity for dominance in in-app advertising and mediation

AppLovin is one of the most significant players in the mobile advertising ecosystem, offering a comprehensive suite of tools that spans user acquisition, monetization, and analytics. Founded in 2012 and headquartered in Palo Alto, California, the company has grown from a mobile marketing platform into a full-stack AdTech powerhouse. Its core platform leverages machine learning and massive data signals to optimize ad delivery, helping app developers acquire high-value users and maximize revenue from their existing user bases. AppLovin's technology stack includes MAX, its in-app bidding and mediation platform, and AppDiscovery, its performance-based user acquisition solution. The company also owns Wurl — a connected TV (CTV) FAST channel distribution platform, acquired in April 2022 for $430M — and operates a portfolio of mobile games through its gaming division, giving it first-party data advantages and direct inventory access. Its AXON AI engine powers campaign optimization across billions of daily ad impressions, making it one of the most data-rich advertising platforms in mobile. AppLovin went public on the NASDAQ in 2021 under the ticker APP and has since become one of the highest-valued AdTech companies globally. It competes directly with ironSource (now part of Unity), Digital Turbine, and indirectly with Google and Meta for mobile advertising budgets. The company's dual role as both a technology provider and a publisher gives it a unique and often controversial position in the ecosystem, but also provides structural advantages in data, inventory, and optimization that few competitors can match.
