Hyperspell is the memory and context layer for AI agents, delivered via an API. It continuously indexes user-connected accounts across tools like Slack, Gmail, Notion, Google Drive, Google Calendar, and Box to build a bespoke memory graph for each organization. This lets AI agents recall, reason about, and learn from a company's collective knowledge, addressing the stateless limitation of typical AI systems. The company is part of Y Combinator's Fall 2025 batch.
