About Composio
Composio develops infrastructure that sits between AI agents and the business applications those agents need to act on. Rather than shipping an agent runtime or a workflow builder, the company supplies the tool layer: a catalogue of application toolkits, managed authentication for each of them, and a protocol surface that agent frameworks call at runtime.
The company was founded in June 2023 by Soham Ganatra and Karan Vaidya, both IIT Bombay alumni. It raised a $4 million seed round backed by Together, followed by a $25 million Series A led by Lightspeed Venture Partners with participation from Elevation Capital, bringing total disclosed funding to $29 million. Headcount was reported at 71 as of 31 May 2026.
Composio holds SOC 2 and ISO 27001:2022 certifications. Its platform is model and framework agnostic, with published SDKs for Python and TypeScript and a REST API at version 3.1 as of August 2026.
