Company Overview

About Letta

Letta (formerly MemGPT) is an open-source AI agent framework developed by researchers at UC Berkeley to solve one of the core limitations of large language models in production: the lack of persistent memory across conversations and tasks. Founded on groundbreaking academic work demonstrating that LLMs could manage their own context windows using a tiered memory system, Letta evolved from a research project into a full-featured agent development platform for building stateful, long-running AI agents.

Business Model & Competitive Advantage

Letta's three-tier memory architecture — separating in-context working memory, external archival storage, and recall memory — enables agents that remember past interactions, learn from experience, and maintain coherent long-term task execution. The framework supports multi-agent orchestration, tool use, and human-in-the-loop workflows, making it suitable for complex enterprise automation tasks. Letta Code, the company's coding-focused agent, achieved the #1 ranking on Terminal-Bench, the leading benchmark for AI coding agents operating in real terminal environments.

Competitive Landscape 2025–2026

Letta raised a $10M seed round from Felicis Ventures, with backing from Google Distinguished Engineer Jeff Dean — a notable endorsement from one of the architects of modern deep learning infrastructure. The Terminal-Bench leadership demonstrates that Letta's memory architecture translates to measurable performance advantages in real-world agentic tasks. As enterprises move from LLM experimentation to deploying persistent AI agents in production, Letta's open-source foundation and research-backed memory system position it as a foundational framework in the agentic AI stack.
