Composio, an agentic AI startup, has raised $25 million in a Series A funding round led by Lightspeed Venture Partners with participation from SV Angel, Blitzscaling Ventures, Operator Partners, and Agent Fund by Yohei Nakajima.
The round also saw participation from several industry leaders, including Guillermo Rauch (Vercel CEO), Dharmesh Shah (HubSpot CTO & Founder), Gokul Rajaram, and Soham Mazumdar (Rubrik Co-founder).
Existing investors Elevation Capital and Together Fund also participated, bringing the total funding to $29 million.
The fresh funds raised will be used to accelerate the development of its learning infrastructure.
Founded in 2023 by Soham Ganatra and Karan Vaidya, Composio provides the learning infrastructure that enables AI agents to improve through experience. Composio integrate AI agents and large language models with their technology stack.
The platform enables developers to integrate AI capabilities into their applications, streamlining the development process. It supports unlimited integrations, suitable for individual developers, startups, and large enterprises.
The platform has attracted over 100,000 developers, with adoption accelerating among AI-first companies. Top companies from the latest YC batches like April, OpenNote, Airweave, Den, and Dash have chosen Composio. Popular AI launches like Context and Altera have also built on the platform. The company serves over 200 startups and enterprises, including Glean.
The platform seamlessly integrates with all major AI frameworks, including MCP, LangChain, Vercel AI SDK, and OpenAI Agents, allowing developers to implement these learning capabilities regardless of their preferred technology stack.
Soham Ganatra, CEO of Composio, said, “You can spend hundreds of hours building LLM tools, tweaking prompts, and refining instructions, but you hit a wall. These models don’t get better at their jobs the way a human employee would. They can’t build context, learn from mistakes, or develop the subtle understanding that makes human workers invaluable. We’re solving this at the infrastructure level.”
He added, “The challenge isn’t making AI smarter in isolation. It’s giving AI the ability to accumulate practical knowledge the way humans do—but at the scale and speed only software can achieve.”
Raviraj Jain from Lightspeed Venture Partners said, “What excites us about Composio is that they’re not just solving today’s integration problems. They’re building the foundation for AI agents to become genuinely useful by learning from experience at scale. This is the missing piece between impressive demos and transformative deployments.”
