TLDR: Cognition AI has announced the acquisition of Windsurf, an AI startup specializing in agentic Integrated Development Environments (IDEs), in a deal signed on July 14, 2025. This strategic move follows a complex period for Windsurf, which recently saw its leadership join Google in a $2.4 billion ‘acqui-hire’ and prior acquisition talks with OpenAI fall through. Cognition aims to integrate Windsurf’s technology, including its $82 million ARR business and over 350 enterprise customers, to accelerate its mission of building the future of software engineering.
San Francisco, CA – July 14, 2025 – Cognition AI, a leading force in AI-powered software engineering, has officially announced its acquisition of Windsurf, a prominent AI startup renowned for its agentic Integrated Development Environments (IDEs). The definitive agreement, signed on Monday, July 14, 2025, marks a significant consolidation in the rapidly evolving artificial intelligence landscape.
The acquisition encompasses Windsurf’s entire intellectual property, its product portfolio—including the Windsurf IDE, now integrated with the latest Claude models—its trademark, brand, and a robust business boasting $82 million in annual recurring revenue (ARR). Windsurf has demonstrated impressive growth, with its enterprise ARR reportedly doubling quarter-over-quarter. The company serves a substantial user base, including over 350 enterprise customers and hundreds of thousands of daily active users. While the financial terms of the Cognition-Windsurf deal were not disclosed, industry analysts suggest it represents a substantial investment given Windsurf’s prior valuation of $1.25 billion a year ago and its successful fundraising of $243 million.
This strategic move by Cognition AI comes after a tumultuous period for Windsurf. Just days prior to this announcement, Google secured a separate $2.4 billion ‘acqui-hire’ deal with Windsurf, primarily aimed at bringing its top leadership and researchers into Google’s fold and licensing its technology. Furthermore, Windsurf had been in extensive acquisition discussions with OpenAI for months, with reports indicating a $3 billion offer. However, these talks ultimately collapsed due to reported tensions with Microsoft, a major OpenAI investor, over concerns regarding access to Windsurf’s proprietary technology.
Scott Wu, CEO of Cognition AI, expressed enthusiasm for the acquisition, stating, “We’re excited to share that Cognition has signed a definitive agreement to acquire Windsurf, the agentic IDE.” He further emphasized the strategic importance, adding, “With this deal, we’re doubling down on our mission of building the future of software engineering.” Wu also noted that the integration of Windsurf’s capabilities and unique IP into Cognition’s products, such as their flagship AI software engineer Devin, will enable the company to “move even faster on our mission.”
Jeff Wang, interim CEO of Windsurf, acknowledged the recent volatility but expressed optimism about the future. In an internal email, he stated that the acquisition “caps off a really volatile time” at the company and that Cognition is “a perfect fit to bring Windsurf to the next phase.” He added, “Among all the teams in the AI space, Cognition was literally the one we have respected the most, and they are a perfect fit to bring Windsurf to the next phase.”
Cognition AI has committed to integrating Windsurf’s world-class talent, including its go-to-market, engineering, and product teams. Scott Wu confirmed that 100% of Windsurf employees will participate financially in the deal, have their vesting cliffs waived for work to date, and receive fully accelerated vesting. This commitment underscores the value Cognition places on the human capital joining its ranks.
