RetainDB

The product is a memory layer for AI agents that stores user preferences, history, corrections, and decisions so agents do not reset each session and can answer from connected tools like Slack, GitHub, and docs. It is for developers and product and data teams building B2B AI products such as customer support agents, coding assistants, research agents, and company copilots. It is delivered as a SaaS infrastructure API with SDK, MCP integrations, and a filesystem interface, starting with durable per-user memory and expanding into a shared company knowledge layer.
