About
ironSource was an Israeli technology company founded in Tel Aviv in 2010, specializing in a comprehensive platform for mobile app developers. It offered solutions for user acquisition, ad monetization, and analytics, enabling creators to manage and scale their applications within the app economy. After going public via a SPAC merger in June 2021 with an $11 billion valuation, ironSource was acquired by Unity Technologies in an all-stock deal valued at $4.4 billion, completed in November 2022.

In March 2026, Unity announced the shutdown of the ironSource Ads Network, effective April 30, 2026, to focus on its AI-powered ad network, Unity Vector. ironSource's Tel Aviv headquarters continues to serve as a significant global hub for Unity's Grow/Ads and Monetization business.
