Letta provides an operating system for AI agents, enabling stateful, long‑term memory and context management so agents can learn and adapt over time. Built by the creators of MemGPT and spun out of UC Berkeley’s Sky Computing lab, Letta delivers persistent state, context compilation, and intelligent resource allocation for developers building agent‑powered applications. By abstracting memory and resource management, Letta lets teams focus on product innovation rather than infrastructure. The company’s deep academic roots and backing from industry leaders such as Ion Stoica and top‑tier investors give it a unique blend of research rigor and commercial viability.
