TLDR: AI coding startup Windsurf, previously known as Codeium, has been acquired by rival firm Cognition in July 2025. This acquisition follows a period of significant financial distress for Windsurf, marked by high operational costs from relying on external large language models, failed funding attempts, and a collapsed acquisition deal with OpenAI. Despite achieving over $82 million in annual recurring revenue and serving over a million developers, the company faced a near-collapse. The acquisition by Cognition also came after Windsurf’s founders and key engineers were separately hired by Google for $2.4 billion, leading to a ‘partial acquisition’ scenario. Cognition has since offered buyouts to approximately 200 Windsurf employees.
AI coding startup Windsurf, a company that aimed to revolutionize software development with its AI-powered environment, has been acquired by Cognition in July 2025, marking a dramatic turn in its recent history. The acquisition follows a tumultuous period for Windsurf, which saw the company on the brink of collapse.
Originally founded four years ago as Exofunction, a GPU virtualization company, the firm underwent a significant pivot in mid-2022, transforming into Codeium, an IDE plugin focused on AI-powered coding assistance. This shift was driven by the rapid rise of transformer models, which threatened to commoditize their initial GPU infrastructure business. A further pivot in mid-2023 led to the creation of Windsurf, a standalone AI-infused development environment, as the company sought to offer a more integrated and superior user experience beyond a mere plugin.
Under the leadership of co-founder and CEO Varun Mohan, Windsurf quickly gained traction, boasting over a million developers using its product within four months and hundreds of thousands of daily active users. The company achieved an impressive annual recurring revenue (ARR) of approximately $82 million at the time of its acquisition, serving over 350 enterprises including major players like Dell and JP Morgan Chase.
However, Windsurf faced substantial financial headwinds. Insiders revealed that the company struggled with high operational costs and negative gross margins, primarily due to its reliance on expensive external large language models (LLMs) from providers like Anthropic. This economic challenge was exacerbated when a planned large funding round at double its previous valuation fell through earlier this year. Subsequently, a potential acquisition by OpenAI, also at a similar valuation, collapsed. Further compounding its woes, Windsurf was abruptly cut off from Anthropic’s Claude models with less than a week’s notice, a move speculated to be linked to the rumored OpenAI deal, highlighting the significant platform risk in the AI ecosystem.
In the midst of this crisis, with Jeff Wang stepping in as interim CEO, Windsurf found itself in a near-collapse situation. Fate intervened when Cognition executives Scott Wu and Russell Kaplan initiated discussions. The intense negotiations over a single weekend led to the acquisition by Cognition, a deal that Jeff Wang described as transforming ‘probably the worst day of 250 people’s lives’ to ‘probably the best day’ in a matter of days.
Adding another layer of complexity to Windsurf’s winding down, Google had previously hired Windsurf’s founders and key engineers in a separate $2.4 billion deal. This ‘partial acquisition’ left over 200 employees behind, facing an uncertain future without their leadership and strategic direction. Following the Cognition acquisition, the new parent company offered buyouts to approximately 200 Windsurf employees, providing nine months of salary. Cognition CEO Scott Wu reportedly presented employees with a choice: accept the buyout or commit to an ‘intense’ work culture, including six-day office weeks and 80-hour workweeks. On August 1, Cognition also laid off 30 Windsurf employees, though no further layoffs are currently planned. Windsurf employees were compensated for four years’ worth of unvested equity, though the exact value was not disclosed.
