Windsurf Statistics 2026: Revenue, Users, and the Devin Desktop Rebrand

Last Updated: September 12, 2026

Windsurf reached $82 million in annual recurring revenue and more than 350 enterprise customers before being acquired by Cognition AI in July 2025 for roughly $250 million, a fraction of the $3 billion OpenAI had reportedly offered just months earlier. Windsurf disappeared as a desktop brand entirely on June 2, 2026, replaced by Devin Desktop. The parent company behind it, Cognition, has since grown to nearly $900 million in annualized revenue and a $48 billion valuation as of a Series E announced within the last week.

Windsurf started in 2021 as Exafunction, a GPU infrastructure company founded by Varun Mohan and Douglas Chen serving finance and healthcare clients. The team pivoted to an AI coding autocomplete tool called Codeium in 2022, then rebranded to Windsurf in November 2024 alongside the launch of its agentic IDE. Growth from there was fast by any standard, crossing 1 million users within roughly 18 months and reaching several hundred thousand daily active users by mid-2025, according to public statements from the company's own CEO.

Enterprise revenue accelerated even faster than the user count. Windsurf's ARR moved from roughly $12 million in the fourth quarter of 2024 to $82 million by the second quarter of 2025, doubling quarter over quarter at points along the way. By the time of its acquisition, the company had signed more than 350 enterprise customers, including Zillow and Dell, and had raised approximately $243 million in disclosed funding across its history.

That growth triggered one of the most chaotic acquisition sequences in recent AI history. OpenAI reportedly agreed to acquire Windsurf for around $3 billion in mid-2025, and the deal collapsed before closing. Google then paid roughly $2.4 billion in a licensing arrangement rather than a full acquisition, hiring Windsurf's founders and a portion of its team directly while leaving the company itself intact. What remained, roughly 210 of the original 250 employees along with the product, brand, and intellectual property, was acquired by Cognition AI on July 14, 2025 for approximately $250 million, with all employee vesting cliffs waived as part of the deal.

The gap between the rumored $3 billion OpenAI offer and the roughly $250 million price Cognition actually paid weeks later is the starkest data point in Windsurf's history, and it reflects how quickly a company's negotiating position can collapse once a preferred acquirer walks away.

Cognition spent the following year integrating Windsurf into its existing Devin product line. On March 19, 2026, it restructured Windsurf's pricing entirely, replacing the old credit-based system with daily and weekly usage quotas and raising the Pro plan from $15 to $20 a month, bringing it in line with Cursor's pricing. On June 2, 2026, the Windsurf brand disappeared entirely from desktop, replaced by Devin Desktop in an automatic update that changed the app's name, icon, and marketing while leaving underlying workflows untouched. Cascade, the original Windsurf agent, was formally retired on July 1, 2026, replaced by Devin Local, a full rewrite in Rust that Cognition describes as up to 30% more token-efficient with added support for parallel subagent sessions.

Is Windsurf still available as a product today? Not under that name on desktop. The June 2026 rebrand was an automatic, over-the-air update, meaning any developer who had Windsurf installed woke up to Devin Desktop without taking any action. A separate Windsurf-branded plugin still exists for JetBrains IDEs, but the primary desktop experience, and all of the company's marketing and product development going forward, runs under the Devin Desktop name. Search interest in the term "Windsurf statistics" is likely to persist for some time simply because the rebrand is recent and much of the public discussion, reviews, and comparison content online still uses the old name.

Because Windsurf's financial results are no longer reported separately, understanding its current scale means looking at Cognition's numbers as a whole.

That revenue growth has been matched by an even steeper climb in valuation. Cognition raised its Series D in May 2026 at a $26 billion valuation, led by Lux Capital, General Catalyst, and 8VC. Roughly four months later, its Series E, raising more than $2 billion, valued the combined company at $48 billion, nearly double its valuation from earlier that same year. Team headcount grew from 44 to 350 employees over the twelve months spanning the Windsurf integration.

The speed of that growth is worth pausing on. A company that paid roughly $250 million for Windsurf in July 2025 was itself valued at $26 billion ten months later, then very nearly doubled that valuation again within another four months. Revenue grew in a similar pattern, climbing from $73 million to $492 million to almost $900 million across roughly fourteen months. Few software categories move that fast, and the pace itself is part of what makes evaluating any AI coding tool's long-term stability difficult for a buyer trying to plan more than a few quarters ahead.

Set against its closest rival, Cognition's trajectory looks even more unusual. Cursor's parent company Anysphere was acquired by SpaceX for $60 billion in August 2026 at roughly 15 times its own annualized revenue. Cognition's most recent Series E values the company at roughly 53 times its own annualized revenue, a richer multiple despite Cognition being a private funding round rather than a strategic acquisition, where buyers can sometimes justify paying more for control and integration than public market investors would for a minority stake.

Cursor, GitHub Copilot, and Devin Desktop now represent three distinct paths to roughly similar market relevance. Cursor built the fastest standalone growth story before being absorbed into SpaceX. GitHub Copilot scaled slowly but steadily behind Microsoft's existing enterprise relationships, reaching 4.7 million paid subscribers without ever needing outside funding of its own. Devin Desktop took the most turbulent path of the three, surviving a near sale, a consolation licensing deal, and a distressed acquisition before ending up inside a company now growing revenue faster than either of its rivals on a percentage basis, even if its absolute revenue still trails Cursor's roughly $4 billion.

Enterprise adoption underpins that valuation. Cognition's disclosed customer list now includes Citi, Goldman Sachs, Mercedes-Benz, Dell, Santander, Elevance, NVIDIA, GE Aerospace, the U.S. Army, the U.S. Navy, and NASA's Jet Propulsion Laboratory, alongside fast-growing technology customers like Exa, Modal, and OpenRouter. One of the more concrete public case studies comes from Nubank, which reported an 8x improvement in engineering efficiency and a 20x reduction in refactoring costs after deploying Devin against a large legacy codebase.

Devin itself, the autonomous coding agent now bundled directly into the Devin Desktop editor, launched publicly in March 2024. A demo video showing it autonomously fixing a bug in an open-source library had drawn more than 30 million views on X as of January 2026, well before the Windsurf rebrand made Devin the default name across Cognition's entire product line.

Cognition's research investment extends beyond Devin Desktop itself. The company has also developed Kevin-32B, a model built with Stanford researchers specifically to generate CUDA kernels, the low-level code that governs how GPUs execute AI workloads. Kevin-32B iteratively revises its own output using compiler errors, correctness checks, and runtime performance feedback, a research direction separate from Devin Desktop's day-to-day coding agent but one that signals Cognition is investing in specialized technical models beyond its consumer-facing product.

Does Windsurf still exist?
Not as a standalone desktop brand. Cognition AI rebranded the desktop product to Devin Desktop on June 2, 2026, in an automatic update. A Windsurf-branded plugin remains available for JetBrains IDEs, but the primary product, and all future development, runs under the Devin Desktop name.

How much revenue did Windsurf make before being acquired?
Windsurf reached approximately $82 million in annual recurring revenue by the second quarter of 2025, up from roughly $12 million just two quarters earlier, with more than 350 enterprise customers signed by the time of its acquisition.

Who owns Windsurf now?
Cognition AI, the maker of the autonomous coding agent Devin, acquired Windsurf's team, product, brand, and intellectual property on July 14, 2025 for approximately $250 million, after an earlier $3 billion OpenAI acquisition attempt collapsed and Google separately paid to license Windsurf's technology and hire its founders.

How much is Cognition worth in 2026?
Cognition was valued at $26 billion in its May 2026 Series D and reached a $48 billion valuation in its Series E, announced within the past week, on annualized revenue of nearly $900 million, up from about $492 million just four months earlier.

What replaced Cascade in Windsurf?
Cascade, Windsurf's original in-editor AI agent, was retired on July 1, 2026, and replaced by Devin Local, a complete rewrite in Rust that Cognition says is up to 30% more token-efficient and adds support for running multiple parallel subagent sessions.

Windsurf's own numbers, an $82 million ARR business with 350-plus enterprise customers, would have made it a solid mid-size AI startup story on its own. What actually happened is stranger: a near-miss $3 billion sale, a $2.4 billion consolation deal for Google, a $250 million fire-sale acquisition, and then a parent company that grew to a $48 billion valuation in the space of about fourteen months. Anyone still searching for "Windsurf statistics" today is really asking about Cognition, whether the data realizes it or not.
