Overview
- Mem0 secured $24 million across a previously unannounced $3.9 million seed and a $20 million Series A led by Basis Set Ventures, with participation from Kindred Ventures, Y Combinator, Peak XV Partners and the GitHub Fund.
- The startup offers a model-agnostic, open-source API that serves as a universal “memory passport” for AI, with direct integrations into developer frameworks such as LangChain and LlamaIndex.
- Adoption metrics include more than 41,000 GitHub stars, over 13 million Python package downloads and 80,000+ cloud signups, with API calls growing from 35 million in Q1 2025 to 186 million in Q3.
- Mem0 is the exclusive memory provider for AWS’s new Agent SDK, positioning its cloud API to handle large-scale memory operations for agents and applications.
- The company frames its approach as a neutral, portable layer to prevent vendor lock-in as major AI labs pursue proprietary memory systems, and it plans to use new funding to scale engineering and enterprise capabilities and deepen platform partnerships.
