Our take

Unity Technologies is one of the world's leading game engines. The platform helps artists and developers in gaming to render 3D worlds in real time.

In recent years Unity has expanded its scope by bringing its technology to new industries, including car companies, and film and TV studios who are using Unity to manage production virtually. 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.
