Composio, a startup with a platform for building artificial intelligence agents, today announced that it has raised $25 million in funding.

Lightspeed Venture Partners led the Series A round. It was joined by SV Angel, HubSpot Inc. founder Dharmesh Shah and more than a half dozen other backers. Composio’s outside funding now stands at about $29 million.

Many of the building blocks necessary to build an AI agent are available in the open-source ecosystem, which spares developers the hassle of writing everything from scratch. But the process can still take upwards of days depending on an agent’s complexity. Composio, officially Sampark Inc., has developed a cloud platform that it says can compress the workflow into a few minutes.

One of the most time-consuming tasks involved in building an AI agent is implementing its authentication workflow. A programming agent, for example, must authenticate itself to GitHub before it can review code stored in the Microsoft Corp.-operated service. The process must be repeated for every development team that connects the agent to its GitHub repository.

According to Composio, its platform automates much of the work involved in implementing agent authentication workflows. That includes the task of managing authentication tokens, which is one of the most complicated chores involved in the process. Authentication tokens are files that have a similar function as passwords.

After developers integrate their agents with Composio, they can connect them to more than 3,000 cloud applications and other software tools. The manner in which agents interact with those tools can be customized. A software team could, for example, require that an agent explain the calculations it performs using a third-party analytics tool.

Developers can also connect custom software tools to their Composio-powered agents. An MCP server, in turn, makes it possible to establish application connections using the Model Context Protocol. The technology automates several of the tasks involved in integrating agents with external systems such as databases. 

Composio is compatible with open-source agent development frameworks such as OpenAI’s Agents SDK. According to the company, those frameworks enable customers to create agents that not only respond to prompts but also carry out actions on behalf of the user.

Under the hood, Composio’s platform is powered by what it describes as a reinforcement learning layer. The company says that the software allows customers’ AI agents to gradually improve their capabilities over time. Furthermore, agents can share information with one another on how to complete tasks. 

“The challenge isn’t making AI smarter in isolation,” said Composio Chief Executive Officer Soham Ganatra (pictured, left, with co-founder Karan Vaidya). “It’s giving AI the ability to accumulate practical knowledge the way humans do—but at the scale and speed only software can achieve.”

Composio disclosed on occasion of the funding round that its installed base includes more than 200 companies. Among those is Glean Technologies Inc., a developer of AI productivity tools that received a $7.2 billion valuation last month. Composio will use the capital to enhance its platform.
