Having completed an IPO in 2020, Unity’s capabilities are also being used by companies such as Apple and Android to create better AR experiences.

In 2021, 72% of the top 1000 mobile games and 50% of games across mobile, PC and console were made with Unity. Having completed substantial post-IPO funding in 2025, the company now operates on over 20 different platforms, is active in 190+ countries and territories across the world and continues to develop its technologies and capabilities.
