Cognition has closed a substantial $400 million funding round at a $10.2 billion post-money valuation. Founders Fund spearheaded the investment, with several existing backers increasing their stakes in the AI coding company.
The round saw strong participation from previous investors, including Lux Capital and 8VC, who jointly led Cognition's earlier funding. Neo, Elad Gil, Definition Capital, and Swish VC also returned to support the company's continued expansion.
The artificial intelligence coding sector has experienced rapid development over the past year. What once seemed like experimental technology has become a practical tool for software development teams worldwide.
Individual developers and large enterprise engineering organizations now regularly deploy AI agents for real programming tasks. This marks a significant shift from early skepticism about automated coding capabilities.
Cognition plans to use the fresh capital to accelerate product development and market expansion following its acquisition of Windsurf. The company's annual recurring revenue jumped from $1 million in September 2024 to $73 million by June 2025, demonstrating strong market demand.
The Windsurf acquisition more than doubled Cognition's ARR while providing access to a complete AI coding product suite. The combined offering addresses both immediate coding assistance through IDE tools and autonomous task delegation through AI agents.
Founded in 2024, Cognition emerged from a team of engineers with a shared vision for software development's future. The company initially gained attention with Devin, an AI software engineer that could handle various programming tasks with varying degrees of success.
Scott Wu leads the company as CEO, building on relationships and expertise developed over more than a decade in software engineering. The founding team operated from a New York apartment in the company's early days, focusing on creating tools they personally wanted to use.
Major enterprises have already adopted Cognition's platforms, including Goldman Sachs, Citi, Dell, Cisco, Ramp, Palantir, Nubank, and Mercado Libre. This client roster demonstrates the technology's readiness for production environments at scale.
Combined enterprise ARR increased over 30% in the seven weeks following the Windsurf acquisition. The companies had less than 5% customer overlap before the deal, creating significant cross-selling opportunities.
New investors joining the round include Bain Capital Ventures, Hanabi Capital, and D1 Capital. Their participation signals broader confidence in AI coding tools' commercial viability and growth prospects.
Two early investors, Christian Lawless from Conversion Capital and Emily Cohen from Neo, made the transition to join Cognition full-time. The company also welcomed swyx, a recognized figure in the AI engineering community, to strengthen its technical leadership.
