ironSource Ltd.

ironSource Ltd.

ironSource was founded in 2011 by Tal Shoham, Tomer Bar Zeev, and Omer Kaplan. The company built a mobile advertising platform focused on app monetization and user acquisition. In July 2022, Unity Software acquired ironSource in a $4.4 billion all-stock deal (per Unity, July 2022), merging ironSource's adtech with Unity's game engine. The combined entity now operates as Unity Grow, headquartered in Tel Aviv, Israel. Unity Grow offers a suite of mobile growth solutions: Unity Ads (AI-powered user acquisition via Vector machine learning), LevelPlay (ad mediation across 25+ networks), Tapjoy from Unity (offerwall monetization), Aura from Unity (pre-installed device monetization on over 2 billion devices since inception, per Unity, June 2025), Supersonic (game publishing), and Unity CTV (connected TV advertising). As of June 2025, the Tapjoy offerwall processed 3.5 million monthly event conversions (per Unity, May 2025). Confirmed customers include Voodoo, mytona, and Japanese studio Barows. Geographic footprint spans over 45 locations globally, per Unity's corporate site. The ironSource workforce was integrated into Unity, which as of 2025 employs over 1.3 million monthly active users of the Unity Editor — this number refers to users of Unity software, not employees. In July 2022, Unity completed the acquisition of ironSource (per Unity, July 2022). In 2023, Unity underwent a restructuring that included layoffs, with ironSource's former CEO Tomer Bar Zeev stepping down from his role as Unity's Growth business head in 2024 (per multiple press reports, 2024). Unity Grow's structural differentiator is its vertical integration: it controls both the game development platform (Unity Engine) and the monetization/ad network. This gives it unique access to game performance data across installs, engagement, and revenue — data that independent ad networks lack, as it flows directly from the engine.
