Composio Revenue and Funding: How Composio Grew to $1M+ ARR

Composio makes "$1 million+ in annualised recurring revenue," co-founder and CEO Soham Ganatra told Forbes India in January 2026, and he declined to share anything more specific. He used almost the same words in July 2025, when he told The Economic Times the company was generating over $1 million in ARR from more than 200 paying companies.

The revenue number is modest. The other numbers are not. Composio has raised about $29 million, including a $25 million Series A led by Lightspeed Venture Partners. By January 2026 it said more than 200,000 developers used the platform and that it processed more than 100 million tool calls a month. In September 2026, its enterprise page listed more than 1 billion tool calls run on the platform and more than 1 million connected accounts.

Composio has not disclosed a valuation.

What follows is how a two-founder company from IIT Bombay became part of the plumbing inside AWS, Glean and Zoom agent products, and why its revenue still looks small next to its usage.

Composio at a glance

Company-reported figures are not audited. Composio's own counts of "tools" and "integrations" have changed definition over time, which is why different sources quote 250, 1,000, 1,500, 3,000 and 10,000.

Composio's growth timeline

Two founders who hated building integrations

Ganatra and Vaidya met at a Physics Olympiad camp and later roomed together at IIT Bombay, according to Lightspeed's investment memo.

Both went on to lead integration work at other startups. Ganatra was the first employee at Bureau, a risk and fraud data company, where he spent about three years and watched it grow through Series B. "At any given point, nearly half the team was working just on integrations," he told Forbes India. Vaidya was one of Rubrik's early engineers, at a time when Glean's future founder Arvind Jain was running that company. That personal link would matter later.

Ganatra had also founded a company straight out of college around 2016 or 2017, selling AI customer support chatbots to Indian banks. He told Forbes India that the experience taught him he did not enjoy relationship-driven enterprise sales, where "the best product doesn't always win."

So the founding thesis was narrow and personal. Integrations eat a large share of engineering time (Ganatra guesses 30 to 40 percent across the industry), nobody enjoys building them, and code-generation models were getting good enough to change how software talks to software. They started Composio in 2023.

The first product aimed at coding agents

Composio did not start as an integrations company. Lightspeed wrote that the founders "initially aimed to use LLMs to automate coding agents," and only while building those agents realized the bigger problem was connecting agents to other applications.

You can still see that origin in the record. In November 2024, LangChain published a guest post about SWE-kit, Composio's open-source headless IDE for coding agents. An agent built with SWE-kit and LangGraph solved 243 of the 500 problems in SWE-bench Verified, a 48.6% score that placed fourth overall and second among open-source entries at the time.

That result gave Composio credibility with agent builders and put its name on LangChain's blog in front of exactly that audience. The coding-agent product then faded into the background. The tool layer underneath it became the business.

Open source as the front door

Composio's SDK is open source under the MIT license. The repository was created in February 2024 and had more than 25,000 stars by July 2025, which Lightspeed cited as proof of developer pull. On September 26, 2026, it had 30,327 stars and 4,829 forks.

For a developer tool, GitHub is a distribution channel in its own right. A developer building an agent searches for a way to give it Gmail or Slack access, lands on the repository, and can try the SDK in minutes without talking to anyone. Lightspeed described the company's growth as "organic, developer-led adoption" and argued that "when developers embrace a platform, enterprise adoption typically follows."

The free usage tier pushes in the same direction. Under the pricing that took effect for new sign-ups on August 15, 2026, the free plan includes 100,000 tool calls, 50,000 trigger events and three team members a month, with a hard cap and no credit card. Most solo builders never need to pay. That keeps the top of the funnel wide, and it also explains why 200,000 developers and "$1 million+" in ARR can both be true at once.

Owning the ugliest part of the stack: auth

The problem Composio picked is not glamorous. When an AI agent sends an email or updates a CRM record on a user's behalf, someone has to run the OAuth flow, store and refresh the tokens, scope the permissions and keep hundreds of API wrappers working as the underlying APIs change.

SiliconANGLE's coverage of the Series A singled out token management as "one of the most complicated chores involved in the process." Composio's pitch was that a developer could integrate once and connect an agent to thousands of apps, with managed authentication handled for them.

This is a classic infrastructure wedge. It is a problem every agent team hits, it is painful enough to pay for at scale, and it gets harder with every new app, which favors a specialist over an in-house build. Lightspeed also pointed to Composio's SOC 2 Type II compliance and "enterprise-grade authentication management" as the features that would let it sell into larger companies.

The same wedge is also a concentration of risk, which Composio would learn the hard way in 2026.

Plugging into every agent framework

Composio made itself framework-neutral early. SiliconANGLE noted in July 2025 that it worked with open-source agent frameworks such as OpenAI's Agents SDK. Its documentation now has guides for OpenAI, Anthropic, the Vercel AI SDK and others, and its blog archive includes tutorials built on CrewAI and GPT-4 function calling.

That neutrality is a distribution strategy. If Composio is the default answer to "how do I give this agent tools," it shows up inside every framework's tutorials and communities without having to win a framework war itself.

It also answers the question Forbes India pressed Ganatra on: foundation labs moving into his space. "LLMs are commoditising faster than software," he said, and customers switch models all the time. A layer that works with every model benefits when they do.

MCP turned Composio into a gateway

Anthropic released the Model Context Protocol in November 2024. Within months, thousands of MCP servers appeared, many of them written by individuals and of uneven quality.

Composio moved quickly. On August 19, 2025, it announced a Universal MCP Gateway that replaced "hundreds of third-party MCP servers" with a single endpoint and more than 500 vetted MCP servers maintained by Composio. The press release described the company as "the MCP infrastructure platform powering 100,000 developers" and said the gateway cut installation from "22+ servers to just one."

The move reframed the company. Before MCP, Composio sold an SDK to developers. After MCP, it could also sell to IT and security teams who wanted one audited connection point instead of dozens of community servers. Its product menu in September 2026 reflects that split: a developer platform, an enterprise tier with SSO, SCIM and self-hosting, and a separate MCP Gateway product.

Tool Router, launched in beta on October 1, 2025, pushed further in the same direction by letting agents search for and load the tools they need at run time instead of having every tool preloaded.

A page for every app and every agent

Composio's content strategy is programmatic and very large. On September 26, 2026, its sitemaps listed:

• 1,612 toolkit URLs, such as pages for individual apps like Jira or Laposta
• 18,434 "framework" pages that pair a toolkit with an agent or client, such as Jira for Claude Code, Cursor, ChatGPT or Antigravity
• 478 articles in its content section
• 64 use-case pages, such as "summarize unread emails" or "deploy latest commit"

Each framework page matches a specific search a developer might type, like connecting a particular app to a particular coding agent. The company also publishes "best apps for Claude content creators" style guides that target people using AI assistants rather than developers.

We could not find Composio data on how much traffic or sign-up volume these pages produce, so their contribution is an inference. But the scale is deliberate. With 1,500 apps and a growing list of agent clients, the number of possible "connect X to Y" pages multiplies, and Composio has built one for most combinations.

Where the page opportunities are for your product

Composio's framework pages come from one idea: every pairing of two things in your product can match a search someone is already making. Okara's SEO Agent looks for those keyword opportunities on your site, and the Coding Agent can ship the technical fixes as GitHub pull requests for you to review.

Anchor customers that lend credibility

A tool layer is only as believable as the agents running on it. Composio has collected some large names.

Its enterprise page says AWS Quick embeds the Composio SDK in its own runtime, every third-party action a Glean Agent Builder agent takes runs through Composio, and Zoom uses it for an assistant that books meetings and updates tickets. A desktop agent called Runner has sent more than two million Slack API calls through it.

The Glean relationship shows how founder networks still matter in developer infrastructure. In Composio's case study, Glean CEO Arvind Jain explains that Glean builds where it is strongest and partners for everything else, and that Vaidya was one of Rubrik's early engineers when Jain ran that company, "which Arvind says made partnering a clear choice." SiliconANGLE had already named Glean as a customer at the time of the Series A.

At the other end of the market, Ganatra told The Economic Times in July 2025 that startups from recent Y Combinator batches, including April, OpenNote, Airweave, Den and Dash, were customers. The mix of YC startups and large platforms is typical for developer infrastructure: startups adopt first because they have no time to build auth, and big platforms follow when they need breadth fast.

Pricing built for usage, not seats

Composio charges for work done, not for people. Its current rate card, effective for new customers from August 15, 2026, looks like this:

• Free: 100,000 tool calls and 50,000 trigger events a month, hard-capped
• Scale: $29 a month including $29 of usage credit, then $0.0003 per tool call and $0.003 per trigger event
• Enterprise: committed volume, custom terms, self-hosting and extras such as HIPAA agreements included

Add-ons such as IP allowlisting, zero data retention and sandboxed execution are billed per call. Premium tools that use Composio's own credentials for services like Google Maps or Exa are billed at the provider's rate plus a 5% platform fee.

At $0.0003 a call, 300 million monthly tool calls would be worth about $90,000 a month if every call were billable at list price. Most are not: many run on the free tier, many come from enterprise contracts with custom pricing, and meta tools like tool search are free. That arithmetic is our illustration, not a Composio figure, but it helps explain why Composio's usage has grown much faster than the revenue number it is willing to share. The company is still pricing for adoption.

Ganatra has said so directly. Composio is "not profitable, and we're not trying to be anytime soon," he told Forbes India, because "we see too many opportunities to reinvest."

From developer SDK to "Composio For You"

Through 2026, Composio broadened its audience beyond people writing code.

Its site now leads with two products. "Composio For You" connects assistants like Claude, ChatGPT, Codex and Cursor to more than 1,500 apps without code. The developer platform remains the SDK and API business. In September 2026, the site also advertised a listing in the ChatGPT plugins directory.

Several launches support that shift:

• March 27, 2026: Universal CLI, a one-command way to add tools and auth to a coding agent
• May 4, 2026: agents themselves can sign up for Composio
• September 14, 2026: Shared Connections, so a team's agents can use one company account, such as a shared mailbox, under access controls

The move makes sense given where agents are being used. Coding agents already run inside developer tools, and Vaidya argued on the AI Engineer podcast in September 2026 that knowledge work is the next frontier, where agents need centralized history, verification and reversible actions before companies will trust them. Composio wants to be the layer those agents act through.

The May 2026 breach

Composio's biggest setback came from the same place as its advantage. A platform that holds tokens for a million connected accounts is an attractive target.

In May 2026, Composio disclosed that an attacker had accessed internal systems and compromised customer credentials. Its incident page says leaked connections represented about 0.3% of active connections, including 5,001 GitHub connections, and that 5,241 Composio API keys were identified as potentially exposed. The company deleted all API keys created before 11:00 PM PST on May 22, 2026, forcing every customer to create new ones.

The remediation list is long. APIs no longer return connected-account tokens or OAuth client secrets, credentials use envelope encryption, API keys are stored only as hashes, and the tool-building service was rebuilt after the attack came through internal tooling and malicious tool definitions. Composio said it engaged IntrusionOps for incident response, that AppSecure re-verified fixes for all critical and high findings, and that Latacora reviewed its AWS and GitHub setup. The company also admitted in its September 16, 2026 update that "our follow-up communication was too quiet."

Separately, security firm Cyera showed in August 2026 research that a Composio API key leaked by a customer in a public repository could return live downstream tokens. That was a customer-side leak, not a Composio breach, but the timing did not help.

We found no public data on customer churn after the incident. The likely effect is a longer security review for new enterprise deals, which is exactly the market Composio's 2026 product line targets.

The bet on a "skill layer"

The Series A was not pitched as an integrations round. Composio's announcement was titled "We raised $29M to build skills that evolve with your agents," and Lightspeed's memo focused on "a shared learning layer" where one agent's lessons about an API edge case improve every other agent on the platform.

Ganatra's analogy for Forbes India was contractors versus employees. A contractor starts from zero on every job. An employee gets better over time. Composio says it already rewrites tools dynamically, strips unnecessary parameters and remembers failure patterns, so that "if one agent makes a mistake, the platform remembers it and all other agents improve."

This is the part of the story that is still a thesis. There is no public benchmark showing how much the learning layer improves accuracy. But it explains why investors were willing to put $25 million into a company with about $1 million in ARR: the value of the network grows with usage, and usage is the number Composio has grown fastest.

What founders can take from Composio

Pick the chore everyone skips. Authentication and API maintenance are nobody's favorite work. That is why a specialist can win them, and why buyers keep paying once they hand them off.

Stay neutral when platforms are fighting. Composio works with every major model and framework. When customers switch models, a neutral layer comes with them.

Let usage run ahead of revenue, deliberately. A 100,000-call free tier and $0.0003 calls made Composio the default for hobbyists and YC startups. The monetization is still catching up, and the founders say that is intentional.

Turn a new standard into a product line fast. When MCP arrived, Composio shipped a managed gateway within months and gained a new buyer: the security team.

Treat trust as part of the product. A tool layer holds the keys to everything it connects. The May 2026 breach showed that the security story is not a feature page. For Composio, it is the product.
