About StackOne
StackOne is the integration infrastructure for AI agents to act. 200+ connectors, 10k+ actions, and the AI builder tools to customize or build your own. StackOne turns AI agents into powerhouse that can act like your and for you. At the core is Falcon, our state-of-the-art, code-first, execution engine. Falcon executes multi-step AI actions accurately, reliably, and securely, optimizing for tool-calling accuracy, token efficiency, and low latency. Falcon interfaces with your agent via MCP, A2A, or API calls for traditional apps RPCs and any app interface (REST, SOAP, GraphQL, Private APIs, browserless). StackOne’s managed infrastructure handles multi-tenant authentication, permissions, and observability out of the box—so teams can focus on designing agency, not building the plumbing. We’re built for enterprise trust: SOC2, GDPR, HIPAA, and CCPA compliant. Real-time execution with no data storage. Ship faster. Execute better. Scale with confidence. StackOne is the platform for production-ready autonomous agents.
