StackOne

Universal Integration Layer

StackOne is a privacy-first embedded IPaaS that equips SaaS platforms and AI agents with a universal integration layer. By abstracting messy enterprise APIs behind normalised data models and AI Agent Actions, product teams can ship and maintain hundreds of deep, bi-directional connectors in days instead of months. Its real-time engine already exposes 3,000+ ready-to-use actions across more than 200 systems spanning HR, CRM, finance, collaboration and IAM categories. Backed by Google Ventures, Workday Ventures, XTX Ventures and angel investors from OpenAI, Deepmind, Github, and more.
