About the Company

Composio

Agentic AI integration infrastructure platform

Composio provides an infrastructure platform that lets AI agents connect to external apps and services through a unified API, handling credentials and tool integrations for 250+ pre-built tools (like Salesforce, HubSpot, Gmail, and Slack). It adds a reinforcement learning layer so agents can learn from experience and share knowledge across the ecosystem, enabling better performance over time. The platform is framework-agnostic and works with LangChain, CrewAI, and OpenAI Agents, reducing integration friction and speeding up development from months to days. Its goal is to help enterprises deploy capable, integrated AI agents at scale by enabling collective learning and easier multi-tool coordination.
