StackOne

Integration infrastructure for AI agents

StackOne is integration infrastructure for AI agents, letting any agent — built into a product or bought off the shelf — take real action across the enterprise stack. Its platform provides over 430 connectors and 26,000 pre-built actions, an AI connector builder for anything not yet covered, and the production layer agents genuinely need: semantic tool discovery that cuts token use by up to 80%, managed authentication and per-action permissions. Those permissions are the part that makes agents deployable in an enterprise at all. Backed by GV and Workday Ventures with $24 million raised.
