Unity Shuts IronSource for Vector AI as Engine Revenue Grows
▼ Summary
– Unity is shutting down its IronSource ad network and plans to divest the Supersonic game publishing unit.
– The company aims to simplify its business and focus on higher-growth segments like its AI-powered Vector ad network.
– The Vector network is showing strong revenue growth, while the IronSource network’s performance has declined.
– Unity’s game engine business remains significant, but it is losing market share to rivals like Godot and Unreal Engine.
– The 2022 merger with IronSource led to internal issues and was linked to the controversial, later-retracted Runtime Fee policy.
The strategic focus at Unity is shifting decisively toward its AI-powered advertising platform, Vector. The company has announced it will shut down the legacy IronSource advertising network on April 30, 2026, and plans to divest the mobile game publisher Supersonic. This move is designed to streamline operations and concentrate resources on what leadership identifies as the highest-growth segments of its business.
This decision follows a clear divergence in performance between the company’s ad products. In the latest fiscal results, the Unity Vector network was credited with driving “mid-teen sequential quarterly revenue growth” and now constitutes 56% of total Grow Solutions revenue. In stark contrast, the IronSource network has seen revenues decline. The departure of IronSource founder Tomer Bar-Zeev earlier this year signaled the changing priorities within the organization.
CEO Matt Bromberg expressed strong confidence in Vector’s trajectory, stating the platform is expected to deliver robust growth each quarter, significantly exceeding the company’s financial guidance. The parallel move to sell Supersonic mirrors a similar strategic pivot by rival AppLovin, which stepped back from game publishing to concentrate on its own successful AI ad product, Axiom. Vector was launched specifically to compete in this high-stakes arena.
While navigating these changes in its advertising business, Unity’s core engine division, Create Solutions, continues to show financial strength. It reported a year-over-year increase of $13 million, reaching $165 million in revenue for the fourth quarter of 2025. However, the competitive landscape for game development tools is intensifying. A recent industry survey indicated Unity is losing some market share to rivals like Godot and Unreal Engine, with the latter now showing equal usage among developers.
The winding down of IronSource closes a turbulent chapter that began with Unity’s merger with the company in 2022. The integration was reportedly fraught with cultural clashes. IronSource was also centrally linked to the disastrous Unity Runtime Fee proposal in 2023, a plan that would have charged developers per install, with fees waived for those using IronSource’s mediation platform. The fierce backlash led to a swift policy reversal and the subsequent exit of then-CEO John Riccitiello.
Following that crisis, nearly the entire IronSource leadership team left Unity in 2024, a year that also saw the company lay off 25% of its workforce. Additional job cuts followed in 2025. The current restructuring marks a definitive effort to move beyond that period and align the company’s future with its most promising technological asset.
