Stealth No More: Sett Raises $27M to Power AI Game Developers

From Stealth to Spotlight

Sett, a new AI startup focused on transforming how video games are developed, has officially emerged from stealth mode with a combined $27 million in seed and Series A funding. Founded by former Google DeepMind and Niantic engineers, the company builds AI agents designed to support game developers throughout the creative process—from early design exploration to live testing on real builds. Sett’s AI tools aim to make development cycles faster and more scalable, especially for teams working on multiplayer and open-world games. Investors include top-tier firms like First Round Capital, Essence VC, and angel backers from Unity, Riot Games, and Activision Blizzard.

AI Co-Developers for a New Era of Games

Sett’s core offering is a “multi-agent” system where specialized AI agents take on tasks like quality assurance, user feedback simulation, and design experimentation. Instead of replacing developers, the system acts more like an intelligent co-developer—one that can tirelessly test balance issues or explore thousands of variations on a level design. This capability is particularly appealing to studios looking to decrease production bottlenecks and maintain consistent player experiences. With the gaming industry in flux due to rising production costs and staff reductions, Sett’s technology could offer a timely alternative to traditional workflows.
