Building at the intersection of AI and games

Established in 2020, Hidden Door is building a new kind of story game experience, powered by a proprietary generative AI platform, that can adapt any existing work of fiction into an online social roleplaying game.

We're excited to collaborate with storytellers from around the world, to create immersive fan-focused story experiences for everyone.

Our Team

We're an intersectional mix of game professionals and AI experts, and a wide range of perspectives, that we’ve recruited to invent a delightful & safe experience for players.
