More about the founding and key events
The company founded in 2021 developed Codeium and later Windsurf. Founders Varun Mohan and Douglas Chen were 27 and 28 in 2024. In July 2025, Google hired some key staff and agreed to license technology. Cognition subsequently acquired the remaining business.
Product leader Kevin Hou described how distribution led to sales. When the free VS Code extension launched in late 2022, its first users were friends and family. More users requested features on Discord, and downloads passed one million. When large companies began asking about enterprise pricing, the team created a contact form and a sales process. Engineers handled the initial sales conversations.
Cognition’s acquisition announcement covered the product, trademarks, intellectual property and business, which then had $82 million in ARR. It also specified measures affecting employee equity compensation and vesting. Understanding the separate Google and Cognition transactions explains what actually changed hands and how participants were treated.
