Less than two months after it acquired rival AI coding platform Windsurf, the San Francisco.startup Cognition today announced it has raised more than $400 million at a $10.2 billion valuation and that the acquisition has paid off handsomely in terms of boosting revenue.
The round was led by Founders Fund with continued support from Lux Capital, 8VC, Neo, Elad Gil, Definition Capital, and Swish VC, alongside new backers Bain Capital Ventures and D1 Capital.
The fact that these big-name VCs are betting on Cognition is notable at a time when overall doubts about the larger AI economy are growing, with some fearing an economic "bubble" of interest and investment, following reports of enterprises struggling to move AI implementations from pilot phase to actual production, and to reap returns-on-investment.
Clearly, like Anthropic's co-founder and CEO Dario Amodei — who recently reported that 90% of his AI firm's code is generated or suggested by AI now — these backers of Cognition also see AI coding tools as a major growth market.
"In code especially, AI has really, really taken off, and all the best software engineers have really changed their workflows," said Cognition CEO Scott Wu in an interview, mentioning Founders Fund partner and former PayPal co-founder and CEO Peter Thiel as a supporter.
He also suggested the company was contemplating "blitz scaling" with the new funding.
Cognition's Rapid Evolution
Following the March 2024 debut of its AI coding agent Devin, Cognition quickly gained traction among AI-forward developers looking to provide natural language instructions and have Devin generate code suggestions for them automatically with minimal human intervention.
Meanwhile, it faced down competition from the likes of other AI coding startups such as Windsurf, which was founded all the way back in 2021 — before the launch of ChatGPT and many of today's leading LLM families.
Earlier this year, Windsurf reportedly attracted attention as a possible acquisition target from OpenAI, but the deal allegedly hit roadblocks from the latter's investor and partner Microsoft with its own rival AI coding platform GitHub Copilot, and ultimately, Google swooped in and made a deal to hire Windsurf's co-founder and CEO (and VB Transform speaker) Varun Mohan, co-founder Douglas Chen, and other key executives in a major talent raid.
Then, in another shocking twist, Cognition agreed to acquire Windsurf's remaining team and tech in July 2025 for an undisclosed sum (estimated to be $250 million).
Now, it turns out that deal has paid off quite well for Cognition. As the company reported in its fundraising annoucnement today:
"Before acquiring Windsurf, Cognition’s Devin [annually recurring revenue] ARR grew from $1M ARR in September 2024 to $73M ARR in June 2025, as usage increased exponentially. Our growth remained efficient throughout, with total net burn under $20M across the company's entire history.
Our acquisition of Windsurf more than doubled our ARR. More importantly, it gave us the complete product suite for AI coding. "
Writing on X, Jeff Wang, CEO of Windsurf, said "our customers can benefit from the opportunities of both products having synergies between local and cloud agents," and envisioned a future of "enabling engineers manage an army of agents to build technology faster."
In addition, since acquiring Windsurf, major customers such as Goldman Sachs, Citi, Dell, Cisco, Palantir, Nubank, and Mercado Libre are now using the combined platform, according to the company.
Two early investors — Christian Lawless of Conversion Capital and Emily Cohen of Neo — have joined Cognition full-time, alongside Windsurf’s team and developer advocate "swyx."
An Intensifying Competition
Cognition’s expansion comes as the AI coding assistant market becomes more crowded and competitive. Microsoft's GitHub Copilot, Amazon Kiro, Anthropic’s Claude Code, OpenAI's Codex, and tools from startups like Sourcegraph and Replit all vie for adoption.
The competition is intensifying as vendors push beyond autocomplete into autonomous “agentic” workflows that can plan and execute multi-step changes across entire codebases.
Enterprise buyers now weigh not just suggestion quality but also deployment flexibility, data security, and the ability to orchestrate parallel agents at scale.
Analysts note that Cognition’s strategy — pairing Devin’s multi-agent task execution with Windsurf’s integrated development environment (IDE) and multi-model support — directly aligns with these evolving priorities. But with large incumbents investing heavily, the pressure to differentiate and prove enterprise value is mounting.
What's next for Cognition, Devin, Windsurf and enterprise customers
Wu said on X that Cognition was founded by a small group of engineers in a New York apartment.
Just over a year later, the company has become one of the highest-valued players in a fast-moving category.
It now emphasizes that while much has changed, its mission to build the future of software engineering remains the same—and it is hiring to expand that mission further.
For enterprise technical decision makers, particularly developer team leads evaluating whether to adopt or expand use of Cognition’s tools, the funding and valuation news provides a measure of stability. With $400 million in fresh capital and backing from prominent investors, Cognition signals that it has the financial strength to continue scaling Devin and Windsurf rather than facing near-term consolidation or shutdown risk.
For teams considering a rollout across hundreds or thousands of engineers, that reassurance matters: it reduces concerns about vendor viability and supports longer-term planning around integrating AI agents and IDEs into day-to-day development workflows.
In other words: betting on Cognition to power developers at your enterprise seems like a winning hand.
