Unity provides software tools and services for game developers, centered on two businesses: a game engine (Create Solutions) and a mobile advertising platform (Grow Solutions). Create Solutions is Unity's core game engine and development platform, built around a "write once, deploy everywhere" model — developers write game code once and deploy across mobile, PC, console, and XR platforms. Developers pay per-seat annual subscriptions to access the engine, with Unity raising prices on professional and enterprise tiers as contracts renew. Around 90% of active creators use the engine for free, with Unity charging once developers launch commercially successful games. Grow Solutions is primarily a performance advertising business, where mobile game publishers pay Unity to drive new player installs through Unity Vector, an AI-powered user acquisition platform. Publishers spend as long as Unity delivers installs that meet their return on ad spend targets, meaning Unity's ad revenue grows by delivering better results rather than just adding more customers. Unity earns a fee on total ad spend flowing through its platform. Grow is the larger segment at roughly 67% of revenue, with Vector growing quickly and the legacy IronSource ad network declining. Create accounts for the remaining ~33% of revenue, with subscriptions making up ~80% of Create revenue. Unity's key strategic bet is integrating real-time behavioral data from its game runtime into Vector's AI targeting models, arguing this proprietary data — drawn from billions of monthly players across Unity-built games — gives it a durable targeting advantage. Unity also works across non-gaming industries including automotive, healthcare, and manufacturing.
