Mem0

Mem0 is an AI memory infrastructure company that builds persistent memory solutions for AI agents and applications. Its technology addresses a structural limitation of large language models - the absence of memory that persists across sessions - allowing AI systems to retain context between interactions. The company is backed by Y Combinator and reports more than 90,000 developers building with its technology.

The Mem0 Memory Platform is the company's core product: a persistent memory layer that developers can use to build AI systems which remember context across sessions and interactions. Alongside the platform, Mem0 offers drop-in SDK integrations for Python and Node.js, designed to add memory capabilities to existing AI applications without substantial changes to the underlying pipeline. A memory compression engine automatically condenses chat history into compact memories, reducing token costs and latency while preserving relevant context.

The technical work spans AI memory infrastructure, persistent memory for LLMs, cross-session context management, memory compression, SDK and integration tooling, and token cost and latency optimization. Mem0's platform is designed for production use and is deployed across healthcare, education, e-commerce, customer support and sales.
