Composio, which provides tools to help companies build AI agents, raised a $25M Series A led by Lightspeed, taking its total funding to $29M
we are responsible with our money https://x.com/... Malay Vasa / @malayvasa : Earlier this month I joined @composiohq, where we're building the skill layer for AI agents so they can continuously learn, adapt, and deliver real value. Thrilled to share we've raised a $25M Series A led by @lightspeedvp to supercharge our vision and make AI agents truly Matt Shumer / @mattshumer_ : I've been working on a new type of advanced agent for months now (will be sharing more info soon). I tried integrating pretty much every MCP service on the market. They all sucked, except for @composiohq. Very cool that they've now raised $25M. This company is going to go far! Caleb / @caleb_friesen2 : THIS is how you make a fundraise announcement video long live Gluely 💪 Robert Scoble / @scobleizer : AI Agent funding door is wide open. Abhinav / @abnux : Websites don't have to be boring. They can be a trippy experience. At @memeticco, we provide memorable design that propagates your company's lore @composiohq gave us $[redacted] to design and develop their brand new website [video] Krishna Mehra / @kpowerinfinity : If you are building AI agents, you can't go “right” unless you use @composiohq — @KaranVaidya6 and @GanatraSoham are creating magic with an army of MCPs and integrations that empower your agents! We @ElevCap are excited to continue backing Karan and Soham, and remain very Apoorv / @apoorv_taneja : i'm beyond excited to share that @composiohq has raised $25M to power the next generation of agents. we're building the smartest, fastest, and most reliable platform so agents don't just exist — they actually get sh*t done. our mission is simple: give developers the tools they Sid Murlidhar / @sidsays : Congrats @KaranVaidya6 , Soham and the Composio team on the fund raise! Composio is well on it way to becoming an essential toolkit for developing agents. 🚀 Brian Zhan / @brianzhan1 : Big congratulations to @KaranVaidya6 and @GanatraSoham and the whole @Composio crew on closing a $29M round! Composio is turning “static prompts” into a living skill graph—every agent learns from every edge‑case fix, so intuition compounds across the network. This is the infra @dharmesh : @KaranVaidya6 ... Congrats! You folks are addressing an important part of the AI landscape. Thrilled to be on board as an indie investor. Hemant Mohapatra / @mohapatrahemant : Super excited to partner with @composiohq as they build the most important layer for AI to become fully agentic in a reliable, repeatable way. Composio's RL is now so good that a customer we spoke to improved multi-tool/multi-step action accuracy from <15% to >90% reducing their Karan Vaidya / @karanvaidya6 : Agents built with @composiohq don't just execute tasks, they evolve like a fleet of waymos learning from each other https://composio.dev/ Karan Vaidya / @karanvaidya6 : Agents aren't reliable. They don't learn from experience. At @composiohq, we provide skills that evolve with your agents @lightspeedvp gave us $25M to make agents usable [video] Raviraj Jain / @ravirajjain : Big news from @Lightspeedvp backed @ComposioHQ. We're excited to announce that we are leading Composio's $25M Series A! Congratulations to Co-Founders @GanatraSoham and @KaranVaidya6 and the entire team.
Context & Ripple Effects
Investment has been spreading across the AI-agent stack rather than concentrating only in model developers: /dev/agents previously raised $56M to pursue a cloud-based operating system for agents that work across devices, while Thinking Machines Lab’s $2B seed round underscored the scale of capital flowing into the broader ecosystem.
Composio sits at the integration and capability layer: its stated aim is to give agents reusable skills and connections so they can learn and act across services. That makes the round relevant to whether agent products can move from model demonstrations to dependable workflow execution.
First-order effects
- Composio gains $25M in new capital, bringing total funding to $29M and giving the company resources to develop and support its AI-agent tooling.
- The financing gives Lightspeed a direct stake in an agent-infrastructure provider, while Composio’s customers and developers gain a better-capitalized integration-layer vendor.
Second-order effects
- Providers of MCP-based services and competing agent-tool platforms face greater pressure to improve integration quality and reliability as Composio uses the funding to strengthen its offering.
- Agent builders can increasingly choose specialized capability layers rather than assembling every connector and action system themselves, reinforcing the market for agent operating-system infrastructure.
Third-order effects
- If agent adoption depends on reliable access to business tools and services, the durable value in the stack may shift toward interoperability, permissions, monitoring, and reusable skills—not solely the underlying models.
- The pattern points to a more modular agent ecosystem, where infrastructure vendors compete to become the default connective layer between models and enterprise workflows; sustained customer use will determine which layers consolidate.
The trend: AI-agent investment is broadening from model creation into the operational layers that let agents connect to software, take actions, and be deployed in real workflows.
