Cognition, the AI startup behind the groundbreaking coding agent Devin, has made a strategic move by acquiring Windsurf, a fast-growing player in the AI-powered development space. This acquisition marks a significant moment in the rapidly evolving world of AI-driven software engineering. By integrating Windsurf’s innovative AI coding IDE and experienced team, Cognition strengthens its position in the competitive landscape currently dominated by players like Cursor, OpenAI, and Anthropic.
The deal not only brings new technology under Cognition’s umbrella but also demonstrates a values-driven approach—ensuring full financial participation for remaining Windsurf employees. As the demand for intelligent developer tools continues to surge, this move positions Cognition to offer a uniquely powerful blend of autonomous agent capabilities and real-time IDE integration.
With Devin at the helm and Windsurf’s platform now in its arsenal, Cognition is set to reshape how developers interact with code, accelerating the future of AI-assisted software development.
The Acquisition: A Rapidly Executed Deal
The Windsurf acquisition unfolded in dramatic fashion. Google had just executed a $2.4 billion reverse-acquihire that brought Windsurf’s CEO Varun Mohan, co-founder Douglas Chen, and several top researchers to its ranks. That move followed the expiration of OpenAI’s $3 billion acquisition offer.
Left behind was a highly capable team of around 250 Windsurf employees, along with proprietary technology that remained independent. Within hours of the Google deal becoming public, Cognition reached out. The first call happened late Friday evening, and by Monday morning, a deal was signed.

Cognition’s Offer: Talent, IP, and Shared Values
Cognition is acquiring Windsurf’s intellectual property, including its AI-powered Integrated Development Environment (IDE), and bringing on board all team members who were not hired by Google. In contrast to the Google deal, which reportedly left many employees without payouts, Cognition stated that 100% of Windsurf’s remaining team will participate financially and will have vesting cliffs waived.
In a LinkedIn post, Jeff Wang, Windsurf’s former head of business and newly appointed interim CEO, expressed optimism:
“To our new teammates at Cognition: we at Windsurf feel incredibly lucky to be joining a team that shares our vision, our deep commitment to our users, and—most importantly—our values.”
Why This Deal Matters: The Battle for AI-Powered Development
The acquisition comes at a pivotal time for the AI coding ecosystem. In the past year, AI-powered IDEs and coding agents have evolved from experimental tools to core development platforms for thousands of developers.
Windsurf’s Growth and Challenges
Despite being smaller than Cursor, Windsurf was on a strong growth trajectory. The company reached $82 million in Annual Recurring Revenue (ARR), with enterprise ARR doubling quarter-over-quarter. It boasted over 350 enterprise customers and hundreds of thousands of daily active users.
Earlier reports even suggested that Windsurf’s ARR had peaked at $100 million. However, in June, Anthropic revoked Windsurf’s access to Claude AI models, following rumors of a potential OpenAI acquisition. This led to user churn, with several clients switching to competitors like Cursor.
Now, under Cognition, Windsurf regains full access to Claude models, giving it the technical foundation to continue scaling.
Devin Meets Windsurf: Combining Agent and IDE Power
Cognition’s flagship product, Devin, is a sophisticated AI coding agent designed to not only assist developers but to act autonomously—almost like a junior software engineer. This agentic approach is bold compared to the more IDE-focused products from Cursor and Windsurf.
However, with this acquisition, Cognition gains the ability to offer both agent-driven automation and a robust developer environment, potentially delivering an end-to-end solution that no competitor currently matches.
Complementary Strengths
- Devin: Automates coding tasks, offers reasoning, and learns over time.
- Windsurf IDE: Offers real-time AI coding assistance in a traditional development environment.
- Combined Platform: A powerful hybrid of autonomy and developer control.
This dual-platform approach could prove valuable as the AI coding market matures and customer needs diversify.
The AI Coding Arms Race Heats Up
The market for AI development tools has become a hotbed of activity, driven by breakthroughs in large language models and deep-pocketed tech giants.
Cursor’s Dominance and Rising Competition
Cursor currently leads the AI IDE space with $500 million in ARR, thanks to early adoption and a stable product. Windsurf, while trailing in revenue, had become a serious contender, evidenced by intense acquisition interest from OpenAI and Google.
With Windsurf now under its belt, Cognition may finally have what it takes to compete on both technological and commercial fronts.
Funding, Valuation, and Strategic Positioning
Earlier this year, Cognition was reportedly in talks to raise hundreds of millions at a $4 billion valuation. While it remains unclear whether that funding round closed, the acquisition of Windsurf signals that the company is either well-funded or has strong backing lined up.
In addition, Cognition recently signed Goldman Sachs as a major enterprise customer—another sign of increasing trust in its offerings.
Industry Reactions and Social Backlash
Despite the celebratory tone of Cognition’s announcement, not all industry observers are pleased. The Google reverse-acquihire left many Windsurf employees—especially recent hires—without payouts. This led to criticism on platforms like LinkedIn and X (formerly Twitter), with some calling the deal exploitative.
In contrast, Cognition’s inclusive financial terms have been widely praised. By offering equity and participation to all remaining employees, the company is positioning itself as a more employee-friendly alternative to the tech giants.
Frequently Asked Questions
