Overview
Mem0 is a drop-in memory infrastructure for AI agents and apps, backed by Y Combinator. It enables AI systems to remember user interactions across sessions and agents, providing persistent context without requiring pipeline changes. Developers use Mem0 to reduce redundant context, lower token costs, and achieve measurably faster responses. The product is built for developers who want proof, not promises, and it's already used by over 90,000 developers.
