ironSource

Leading mobile app monetization platform, now part of Unity Technologies

ironSource is a comprehensive business platform for the mobile content economy that provides app developers with tools for app monetization, user acquisition, and analytics. Founded in 2010, the company built one of the industry's largest in-app bidding mediation platforms, connecting thousands of app developers with advertisers through its sophisticated ad exchange technology. The platform became particularly dominant in mobile gaming, offering solutions that helped developers maximize revenue through optimized ad placements and cross-promotion tools. In July 2022, Unity Technologies completed its acquisition of ironSource in a $4.4 billion deal, merging ironSource's monetization and user acquisition capabilities with Unity's game development engine. Following the acquisition, ironSource's technology continues to operate as Unity's Grow Solutions division, maintaining its core products and brand presence in the market. The combined entity aims to provide an end-to-end platform for game developers, from creation through monetization and growth. Today, ironSource's platform continues to serve over 200,000 apps and reaches more than 1.5 billion monthly active users globally. The technology remains a critical component of the mobile app ecosystem, particularly for hypercasual and casual game developers who rely on ad-based monetization strategies. The platform's mediation technology, real-time bidding capabilities, and comprehensive analytics tools continue to compete with other major mobile ad platforms in the market.
