“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,” said Soham Ganatra, CEO of Composio, in a statement.
The startup will use the fresh capital to fuel the development of its learning infrastructure for its agentic AI offerings.
While traditional AI agents operate in isolation without improvement over time, the platform claims to enable systems that learn from each interaction.
“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,” said Raviraj Jain, Partner, US Enterprise, Lightspeed Venture Partners.
The San Francisco, California-based startup has built a reinforcement learning framework that allows AI systems to learn collectively and develop intuition through experience—a capability it claims is absent in traditional AI systems.
When one agent masters a specific use case, that expertise becomes immediately accessible across the entire network.
Developers typically spend months building authentication and debugging integrations. With Composio, they can deploy agents in days using pre-built tools. These agents launch with knowledge from thousands of previous deployments.
The platform has drawn over 100,000 developers, along with gaining attention from recent Y Combinator cohorts, including April, OpenNote, Airweave, Den, and Dash. It added that AI startups such as Context and Altera have also been built on the platform.
The company counts over 200 startups and enterprises, including AI startup Glean, which was valued at $7.2 billion following its $150 million Series F round last month.
Founded in 2022 by IIT-Bombay alumnus Soham Ganatra and Karan Vaidya, provides tools that assist developers to quickly create reliable AI agents that interact with external software, like CRM systems (e.g., Salesforce, HubSpot) and services like Gmail.
