Agentic AI startup Composio has raised $25 million in a Series A funding round led by Lightspeed Venture Partners.
Other investors who joined include Elevation Capital, Together Fund, and angel investors like Gokul Rajaram, Rubrik co-founder Sohum Mazumdar, Dharmesh Shah, and others.
The startup will use this money to hire more engineers and researchers. Composio, based in San Francisco and Bengaluru, had previously raised $4 million in a seed round.
“You can spend hundreds of hours building LLM tools, tweaking prompts, and refining instructions, but you hit a wall,” said Soham Ganatra, CEO of Composio. “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.”
“What excites us about Composio is that they’re not just solving today’s integration problems,” said Raviraj Jain of Lightspeed Venture Partners. “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.”
Composio was started in 2023 by Soham Ganatra and Karan Vaidya. It uses AI to make complicated business workflows easier by letting AI agents connect directly to popular apps like Gmail, GitHub, Salesforce, and Slack. It works as a link between AI tools and business software.
The platform offers ready-made connections so AI agents can do tasks like sending and organizing emails, updating customer records, handling support tickets, and working with code—without developers needing to build or manage these connections themselves.
Composio says more than 100,000 developers are using its platform, and AI-focused companies are showing more interest. Some customers are top startups from recent Y Combinator groups, including April, OpenNote, Airweave, Den, and Dash.
The company also has over 200 paying clients and earns more than $1 million every year.
