About Hyperspell
Summary
Hyperspell builds a persistent memory layer for AI agents, giving them access to a continuously updated, permission-aware knowledge graph built from a company's existing tools: Slack, Gmail, Notion, Linear, HubSpot, and more. Developers connect Hyperspell via API or SDK so their agents can recall past decisions, understand relationships between people and projects, and act on current context rather than isolated text fragments. It replaces the manual work of wiring agents to disparate data sources and the lost institutional knowledge those agents would otherwise lack.
Business model
API and SDK access for developers, with a demo-gated sales entry point.
Go-to-market
Developers and engineering teams at companies deploying AI agents are the buyers; they connect via OAuth in minutes and integrate through a universal API, SDK, or pre-built connectors, with enterprise deals initiated through a book-a-demo flow.

Memory for AI Agents
Hyperspell (YC F25) gives AI agents memory. It connects to tools like Slack, Gmail, Notion, and Drive so agents can recall, reason, and remember across company knowledge. Developers use Hyperspell’s API to turn disconnected agents into AI coworkers that understand their work. Conor and Manu founded Hyperspell after building their own workplace agent and seeing how limited AI is without memory. They have over 15 years of experience in machine learning and have scaled API-based products to $30M ARR.
