Artificial intelligence startup Cognition announced it's acquiring Windsurf, the AI coding company that lost its CEO and several other senior employees to Google just days earlier.

Cognition said on Monday that it will purchase Windsurf's intellectual property, product, trademark, brand and talent, but didn't disclose terms of the deal. It's the latest development in an AI talent war, as companies like Meta, Google and OpenAI fiercely compete for top engineers and researchers.

OpenAI had been in talks to acquire Windsurf for about $3 billion in April, but the deal fell apart, and Google said on Friday that it hired Windsurf's co-founder and CEO Varun Mohan. Google is paying $2.4 billion in licensing fees and for compensation, as CNBC previously reported.

"Every new employee of Cognition will be treated the same way as existing employees: with transparency, fairness, and deep respect for their abilities and value," Cognition CEO Scott Wu wrote in a memo to employees on Monday. "After today, our efforts will be as a united and aligned team. There's only one boat and we're all in it together."

Cognition didn't immediately respond to CNBC's request for comment. Windsurf directed CNBC to Cognition.

Cognition is best known for its AI coding agent named Devin, which is designed to help engineers build software faster. As of March, the startup had raised hundreds of millions of dollars at a valuation of close to $4 billion, according to a report from Bloomberg.

Both companies are backed by Peter Thiel's Founders Fund. Other investors in Windsurf include Greenoaks, Kleiner Perkins and General Catalyst.

"I'm overwhelmed with excitement and optimism, but most of all, gratitude," Jeff Wang, the interim CEO of Windsurf, wrote in a post on X on Monday. "Trying times reveal character, and I couldn't be prouder of how every single person at Windsurf showed up these last three days for each other and for our users."

Wu said that the acquisition ensures all Windsurf employees are "treated with respect and well taken care of in this transaction." All employees will participate financially in the deal, have vesting cliffs waived for their work to date and receive fully accelerated vesting for their, according to the memo.

"There's never been a more exciting time to build," Wu wrote.
