About
One of the top mobile monetization and mediation platforms globally, now integrated within Unity Technologies
ironSource is a prominent mobile growth platform that provides app developers and publishers with a comprehensive suite of tools for monetization, user acquisition, analytics, and engagement. Founded in 2010 and headquartered in Tel Aviv, Israel, the company built one of the most widely used mediation and in-app bidding platforms in the mobile ecosystem, enabling developers to maximize revenue from their apps while efficiently acquiring high-quality users at scale. Its flagship products, including the LevelPlay mediation platform and Supersonic Studios, became industry standards for mobile game and app developers worldwide. In 2022, Unity Technologies acquired ironSource in an all-stock deal valued at approximately $4.4 billion, combining Unity's real-time 3D development engine and creator ecosystem with ironSource's monetization and growth infrastructure. The merger was designed to create an end-to-end platform for mobile game developers, covering everything from game creation to distribution, monetization, and live operations. The combined entity aimed to serve the full lifecycle of a mobile app, positioning itself as a uniquely integrated solution in the competitive mobile AdTech space. As part of Unity, ironSource's technology and products have been integrated into Unity's broader advertising and monetization offerings. The ironSource brand and platform continue to serve a large global customer base of mobile developers, publishers, and advertisers, with particular strength in the mobile gaming vertical. The platform competes with major players such as AppLovin, Google AdMob, and Meta Audience Network, and is recognized for its robust mediation stack, rewarded video ad formats, and data-driven user acquisition capabilities.
