Composio, officially known as Sampark Inc., announced on July 22, 2025, that it has secured $25 million in Series A funding, bringing its total outside funding to approximately $29 million. The round was spearheaded by Lightspeed Venture Partners, with significant participation from a diverse group of investors including SV Angel, HubSpot Inc. founder Dharmesh Shah, Vercel CEO Guillermo Rauch, Gokul Rajaram, Rubrik Co-founder Soham Mazumdar, Blitzscaling Ventures, Operator Partners, Agent Fund by Yohei Nakajima, and existing investors Elevation Capital and Together Fund.
The San Francisco, CA-based startup specializes in providing a learning infrastructure designed to enable AI agents to improve their capabilities through experience. Composio’s cloud platform aims to significantly ease and accelerate the development of artificial intelligence agents, compressing workflows that typically take days into mere minutes.
A core challenge in AI agent development, such as implementing authentication workflows for agents interacting with services like GitHub, is largely automated by Composio’s platform. This includes the complex task of managing authentication tokens. Once integrated with Composio, developers can connect their agents to over 3,000 cloud applications and other software tools, with customizable interactions.
Underpinning Composio’s platform is a reinforcement learning layer that allows AI agents to gradually enhance their performance over time. Furthermore, this innovative system facilitates the sharing of practical knowledge among agents, fostering a collaborative learning environment. Soham Ganatra, CEO of Composio, emphasized this vision, stating, “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.”
