General information

Letta is an AI research lab that builds machines that learn. Its main product is Letta Agent, a self-improving AI agent whose memory, identity and capabilities evolve with experience. Letta is based in San Francisco.

Letta was founded by the creators of MemGPT from UC Berkeley's Sky Computing Lab. The company came out of stealth in September 2024, so it is still young, built on research roots in AI memory systems rather than a long commercial track record. Letta is an H-1B sponsor.¹
