Memory Store

Memory Store is a Y Combinator (Spring 2026) startup building a universal, shared memory layer for teams and AI agents. It automatically collects insights from communication and productivity tools — Gmail, Slack, Granola, Claude, ChatGPT and more — and synthesizes them into an organized, searchable "company brain." Memory Store is delivered primarily as a Model Context Protocol (MCP) server, letting AI clients such as Claude, ChatGPT, Cursor and Raycast record what matters and recall it anywhere without changing existing workflows. A signature feature, "Briefs," maintains self-updating living documents (decision logs, team status, customer requests) as new information arrives.

Memory Store publishes 1 API on the APIs.io network. Tagged areas include Company, Memory, AI Agents, Model Context Protocol, and MCP.

Memory Store’s developer surface includes documentation, getting-started guide, signup flow, pricing, engineering blog, support, and 9 more developer resources.
