The problem with building an AI agent that can actually do something is that the world runs on APIs. Getting a large language model to reliably book a calendar slot, update a CRM, or file a GitHub issue means navigating a thicket of authentication schemes, rate limits, and JSON schemas. Composio, a San Francisco-based developer platform, is betting that abstracting this mess away is the wedge into the next layer of enterprise AI infrastructure.
Founded in 2023 by Soham Ganatra and Karan Vaidya, Composio provides SDKs that let developers connect AI agents to external tools with a few lines of code [Composio, retrieved 2024]. The platform handles the underlying authentication, session management, and API call execution, offering a unified interface to over 850 integrations [Composio, retrieved 2026]. The more ambitious bet is that by managing these connections at scale, Composio can build a shared learning layer where successful agent actions across its customer base improve performance for everyone [CNBC-TV18 / Startup Street, YouTube, 2025].
The infrastructure wedge
Composio’s play is classic B2B infrastructure. It doesn’t sell the AI agents themselves but the pipes they need to interact with the real world. The platform’s documentation emphasizes enterprise-grade features like SOC 2 certification, granular access controls, and full observability [Composio, retrieved 2024]. Its usage-based pricing starts with a free tier (20,000 tool calls per month) and scales up [Composio, retrieved 2024].
CEO Soham Ganatra stated in a 2025 interview that Composio was powering over 200 companies, serving more than 100,000 developers, and processing millions of requests per day, with revenue in the seven-figure range [CNBC-TV18 / Startup Street, YouTube, 2025].
Why Lightspeed wrote the check
The company has raised a total of approximately $29 million in a Series A round led by Lightspeed Venture Partners [CNBC-TV18 / Startup Street, YouTube, 2025] [YourStory.com, 2026].
| Metric | Value |

| Series A (July 2025) | $29M |
The capital is earmarked to accelerate development of the platform’s learning infrastructure [Pulse2.com, 2026].
The realistic competitive set
Composio’s competitive landscape includes in-house development, major cloud platforms like AWS Bedrock, legacy automation giants like Salesforce (MuleSoft), and API aggregators. Composio’s wedge is its specific focus on the AI agent developer, with features like just-in-time tool calls and sandboxed environments [Composio, retrieved 2024].
Where the execution risks lie
The market for AI agent infrastructure is nascent. The company’s cited traction comes primarily from founder interviews rather than named customer case studies. Selling to individual developers is one thing; securing seven-figure enterprise deals is another. The platform’s enterprise page lists the right features, but the proof will be in landing and expanding with flagship customers.
The next twelve months
The coming year will be about proving the enterprise case. Watch for Composio to start publicly naming design partners or flagship customers in regulated industries like finance or healthcare. The ideal customer profile is the head of engineering or CTO at a mid-market tech company or innovative enterprise division.
