Codeium Valuation From $1.25B Funding to the Windsurf Acquisition

Update: This article was revised on August 19, 2026, to distinguish Codeium’s confirmed $1.25 billion valuation from later proposed transactions and to add the Windsurf rebrand, Cognition acquisition, and Devin Desktop transition.

Codeium’s last confirmed standalone valuation was $1.25 billion, set when the AI coding startup announced a $150 million Series C in August 2024. The much larger figures that followed including a possible $2.85 billion funding round and a reported $3 billion sale to OpenAI described negotiations, not a new standalone valuation that can still be applied to Codeium today.

The company changed substantially after those reports. Codeium renamed itself Windsurf, lost its founders and members of its research team in a Google licensing and talent transaction, and then agreed to be acquired by Cognition. In June 2026, Cognition introduced Devin Desktop as the next generation of Windsurf.

That timeline changes the answer to the original question. Codeium had real growth signals, but there is no defensible public figure for a current standalone codeium valuation after the business was rebranded and acquired.

Codeium’s Last Confirmed Valuation Was $1.25 Billion

Codeium announced a $150 million Series C at a $1.25 billion valuation on August 29, 2024. General Catalyst led the round, with Kleiner Perkins and Greenoaks also participating.

The financing was the last publicly confirmed standalone valuation event for Codeium. In its announcement, the company said it had grown to more than 700,000 active individual users in under two years. It also said its enterprise product had reached eight figures in annual recurring revenue and that ARR had increased by more than 500% since the start of 2024.

Those numbers help explain the investor interest, but they should be treated as company-reported operating metrics. They do not independently prove that a later multibillion-dollar valuation was completed.

What the $2.85 Billion and $3 Billion Figures Actually Meant

In February 2025, TechCrunch reported that Codeium was discussing a new financing at a $2.85 billion valuation, including fresh capital. A company can negotiate a target valuation without closing a round at that price, so the report should not be presented as a completed valuation.

A second figure appeared after Codeium had become Windsurf. In May 2025, Reuters reported that OpenAI had agreed to acquire Windsurf for about $3 billion, citing Bloomberg. Reuters also said the transaction had not closed.

The distinction matters:

Treating all four numbers as steps in a single valuation climb would be misleading.

Codeium Became Windsurf Before the Deals Changed the Company

Codeium launched the Windsurf Editor in November 2024 as a more integrated environment for developers working with AI. On April 4, 2025, the company officially renamed itself Windsurf and renamed its original Codeium extensions as Windsurf Plugins.

The product shift was important to the growth story. Codeium had started with autocomplete, chat, and coding assistance inside existing editors. Windsurf placed a larger emphasis on an agentic IDE that could reason across a codebase and take multi-step actions while a developer remained involved. That evolution reflected the broader move from simple code suggestions toward coding agents.

It also means that later reports about Windsurf were reports about the company formerly known as Codeium, not a separate startup with a separate early funding history.

The 2025 Transactions Ended the Standalone Valuation Story

The reported OpenAI acquisition did not become Windsurf’s outcome. In July 2025, Google entered a reported $2.4 billion arrangement for technology licensing and to bring Windsurf co-founder Varun Mohan, co-founder Douglas Chen, and selected research personnel to Google DeepMind.

Days later, Cognition agreed to acquire Windsurf. Reuters reported that the deal covered Windsurf’s intellectual property, product line, brand, business operations, and engineering, product, and go-to-market teams. The purchase price was not disclosed.

Reuters also reported that Windsurf had reached $82 million in annual recurring revenue and served more than 350 enterprise customers. Those figures provide stronger evidence of commercial traction than the original article’s generic claims about demand. They still do not establish a public sale valuation for the Cognition transaction.

The Google payment should not be described as Google buying Windsurf for $2.4 billion. The operating business and remaining assets went to Cognition under a separate agreement.

What Happened to the Product After Cognition’s Acquisition

Cognition initially combined Windsurf’s agentic development environment with Devin, its autonomous software-engineering agent. On June 2, 2026, the company announced that Windsurf was becoming Devin Desktop.

Devin Desktop retained an integrated development environment while adding a command center for managing local and cloud agents. Cognition said existing Windsurf users would receive the change as a standard update and keep their plans, pricing, extensions, and other features.

This was another product transition, not a new Codeium funding round. By this stage, Codeium’s technology and customer base were part of Cognition’s broader product strategy.

Does Codeium Have a Current Valuation?

No current standalone Codeium valuation has been publicly disclosed. The most accurate way to describe the record is:

• $1.25 billion was Codeium’s last confirmed financing valuation.
• $2.85 billion was a reported fundraising target.
• About $3 billion was a reported OpenAI acquisition price for a deal that did not close as reported.
• $2.4 billion referred to Google’s separate licensing and talent arrangement.
• Cognition’s purchase price for the remaining Windsurf business was not disclosed.

Codeium’s growth was supported by meaningful product adoption, enterprise revenue, and investor demand. But after the Windsurf rebrand and Cognition acquisition, presenting any of the reported 2025 figures as Codeium’s current valuation would confuse a historical benchmark with transactions that had different structures and outcomes.
