Unity Experiences Revenue Growth, Discontinues IronSource Ad Network in Favor of Vector AI

Unity has announced the shutdown of its IronSource advertising and user-acquisition network, as well as plans to divest Supersonic, a publisher of popular mobile games such as Bridge Race, Going Balls, and Build A Queen. This move aims to simplify the business and enable the company to focus on higher-growth segments, including its AI-powered ad network Vector. The decision was included in the company's latest investor update. The news follows a decline in performance for the IronSource ad network and significant growth for Vector. In its fiscal 2025 results, Unity reported mid-teen sequential quarterly revenue growth from Unity Vector, which accounts for 56% of total Grow Solutions revenue, while IronSource ad network revenues declined. Vector, launched in 2025, is expected to drive robust growth each quarter, with Unity CEO Matt Bromberg stating that it will deliver results above the company's guidance. The IronSource ads network is set to be shut down on April 30th, 2026. The proposed divestment of Supersonic echoes Unity rival AppLovin's retreat from game publishing, with AppLovin focusing on its successful AI ad product Axiom. Unity's platform remains a popular choice for game development, but the most recent GDC survey showed a decline in market share to Godot and Unreal Engine. The company reported a year-over-year increase of $13 million to $165 million in its engine business, Create Solutions, in the fourth quarter of 2025. Unity merged with IronSource in 2022, but the integration reportedly led to internal issues due to differing work cultures. The entire IronSource leadership team departed Unity in 2024, following significant layoffs. Further layoffs were carried out in 2025.
