Letta is an AI infrastructure company founded by UC Berkeley PhD students Sarah Wooders and Charles Packer, who built MemGPT — a memory-augmentation research project — at Berkeley's Sky Computing Lab before spinning it out as a company in September 2024 with $10 million in seed funding. The company builds open-source tooling for stateful AI agents — systems that can remember users and adapt from experience over time — and positions itself as an open alternative to proprietary platforms.
