StackOne is the universal integration layer for modern SaaS products. We’ve raised $24 m in two years and are backed by top‑tier investors such as Google Ventures and Workday Ventures. Our unified API platform lets vendors ship hundreds of native, white‑label integrations in days, not months, by abstracting dozens of disparate third‑party APIs into a single, normalized interface. On top of those APIs, we provide AI Agent Actions so customers can build agentic workflows without wrangling OpenAPI specs. StackOne sits behind the scenes as an embedded iPaaS: SOC 2 compliant, multi‑tenant, and invisible to end users, powering integrations for future‑of‑work SaaS categories such as HR, Compliance, and AI Agents.
