Clockwork Labs

San Francisco-based, remote-first studio founded in 2019 by Tyler Cloutier and Alessandro Asoni to build massively multiplayer "societal games", backed by a16z and Supercell among others. It built SpacetimeDB, the database-engine backend its sandbox MMO BitCraft Online runs on, launched BitCraft into Steam early access in June 2025, and open-sourced both the engine and the game's own server and client code.
