“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.”

About Composio 

Co-founded in 2023 by Soham Ganatra and Karan Vaidya, Composio uses AI to simplify complex enterprise workflows by allowing AI agents to directly connect with popular business apps like Gmail, GitHub, Salesforce, and Slack. It acts as a bridge between AI tools and enterprise software systems.

The platform provides ready-to-use integrations so AI agents can handle tasks like sending and sorting emails, updating CRM entries, managing support tickets and working with code repositories—without developers needing to build or maintain custom connections or handle login setups.
