About the company

StackOne provides a tool gateway that sits between AI agents and business applications, enabling assistants to read and act in HR, finance, IT, and CRM while enforcing per-person permissions. It combines an MCP gateway with 580+ connectors and 36,000+ actions, and supports MCP, A2A, SDKs, and APIs, plus an AI connector builder; it discovers and loads only the tools needed for a task and enforces security policies and audit logs. The platform differs by offering a large ecosystem of connectors and pre-built actions, strong governance and security features, and an OEM embedding option, while legacy HRIS, ATS, and CRM APIs remain available. Its goal is to help organizations deploy AI assistants across teams quickly and safely by providing a scalable, governed tool layer for AI agents.

Simplify's Take

What believers are saying

  • GV led StackOne's $20 million Series A on May 6, 2025, funding expansion.
  • StackOne claims 100k+ evals and 78% average tokens saved on its September 2026 site.
  • Continuous connector shipping and MCP/A2A support widen adoption among AI-agent builders.

What critics are saying

  • Merge, Workato, and MuleSoft compress pricing as connector commoditization accelerates by 2027.
  • Prompt-injection or token-lifecycle failures on StackOne Hub trigger enterprise security reviews immediately.
  • A major platform outage sends AI-agent builders back to direct API integrations.

What makes StackOne unique

  • StackOne spans 510+ connectors and 31,000+ actions across AI clients.
  • Its Documents API unifies Notion, Confluence, Google Drive, SharePoint, and OneDrive access.
  • Built-in prompt-injection defense and StackOne Hub simplify secure, real-time agent connections.
