Inside ‘Cognition Windsurf’, the Viral Mind-Hacking Technique Making Waves in Watersports

AI coding-assistant company Cognition has reached a definitive agreement to acquire developer-tool startup Windsurf, consolidating the remains of the once–high-flying firm just weeks after Google secured a non-exclusive license to its technology and hired its founding team. According to a joint statement, Cognition will purchase Windsurf’s intellectual property, brand, cash reserves and the roughly 40 engineers who stayed after Google’s talent pickup. All employees will receive accelerated vesting and share in future upside, mirroring the employee-friendly structure Cognition used when it absorbed code-review platform Surfer last year. WHY THE DEAL MATTERS • Completes Windsurf’s breakup: Google gets the founders plus a perpetual license; Cognition gets the core product and remaining staff, avoiding an IP tug-of-war and ensuring customers retain uninterrupted access. • Bolsters Devin, Cognition’s AI software engineer: CEO Scott Wu said Devin will be “deeply integrated” into the Windsurf IDE, allowing the assistant to generate, debug and ship code inside a battle-tested developer environment. • Keeps talent in play: Windsurf’s veteran compiler and tooling engineers join Cognition instead of dispersing, shoring up the startup’s push to compete with GitHub Copilot, Replit Ghostwriter and Google’s Gemini Code Assist. TERMS & TIMELINE Neither company disclosed a price, but investors familiar with the talks peg the consideration below Windsurf’s last private valuation of $900 million after its 2024 Series B. The transaction is expected to close in Q3 2025, pending customary regulatory approvals, with the combined engineering team headquartered in San Francisco and maintaining a satellite office in Toronto. STRATEGIC CONTEXT The acquisition underscores how intensely large-language-model startups are competing for scarce compiler, runtime and developer-experience talent. Google’s parallel move illustrates a “buy-and-license” playbook: capture founders for Gemini, grant IP rights to fend off legal risk, then let another buyer assume operating costs. Cognition, backed by Founders Fund and Index Ventures, gains a differentiated desktop IDE and a paying user base of nearly 120,000 monthly active developers, expanding its revenue mix beyond usage-based API calls. WHAT’S NEXT Cognition plans to open-source key components of Windsurf’s static-analysis engine later this year, a step it says will “drive community trust and benchmarking transparency.” It will also sunset Windsurf’s standalone subscription tiers in favor of a unified Cognition+ plan, priced at $29 per seat for individual devs and $39 per seat with enterprise governance. Existing Windsurf customers will receive a 12-month grace period at current rates. For developers, the short-term impact should be minimal—log-ins, projects and cloud builds will port automatically—while the long-term upside could be a more capable, context-aware AI engineer embedded directly in their editor. Investors, meanwhile, view the deal as another sign that consolidation, not endless venture funding, will shape the next chapter of the AI tooling boom.
