About us
Building machines that learn
The human brain is a sponge. Today’s AI brains are brittle and rigid. At Letta, we’re building self-improving artificial intelligence: agents that continually learn from experience and adapt over time.
Founded by the creators of MemGPT from UC Berkeley’s Sky Computing Lab (the birthplace of Spark and Ray). Backed by Jeff Dean, Clem Delangue, and pioneers across AI infrastructure.
Memory is more valuable than the model
Every AI interaction should build on the last. Memory will become more valuable than the models themselves — state that persists across providers, enabling agents to evolve from their own lived experience.

Open AI and model freedom
The true potential of AI is realized by making it open and accessible. AI systems are more resilient, reliable, and trustworthy when they are built using open technology. The real AI danger is Closed AI.

Power to the developers
Developers will turn foundation models into the next generation of applications, so they shouldn't be restricted by black-box models and APIs.

Nimble, talent-dense teams
We believe in small, exceptional teams: one 10x engineer is better than ten 1x engineers.

Flat structure & high trust
We believe in a flat company structure where every employee is trusted to drive their own work.

Wein-person work
Creativity, community, culture, and trust thrive in person. We're fully in-person in the heart of San Francisco.
