About
Mem0 (pronounced "mem-zero") is an open-source memory infrastructure layer for AI agents and applications, enabling large language model-powered systems to remember information across conversations, user interactions, and sessions. Founded in 2023 and backed by Y Combinator, the company addresses a fundamental limitation of current LLMs: they process each conversation independently without retaining information from previous interactions. Mem0's system allows AI agents to store, retrieve, and update memories — user preferences, past decisions, domain knowledge, and interaction history — persisting them across time and sessions.
