Windsurf

Windsurf, formerly known as Codeium, is a leading AI-powered integrated development environment (IDE) that revolutionizes software development through its agentic coding capabilities. Founded in 2021 by Varun Mohan and Douglas Chen, the company initially focused on GPU virtualization before pivoting to AI-driven coding solutions. Windsurf's flagship product, the Windsurf Editor, integrates advanced features like Cascade, an AI agent that understands and modifies complex codebases, and Supercomplete, which offers predictive code suggestions. These innovations have positioned Windsurf as a formidable competitor in the AI coding tools market, attracting over 800,000 developers and 1,000 enterprise customers. In May 2025, OpenAI agreed to acquire Windsurf for approximately $3 billion, marking its largest acquisition to date. This strategic move aims to bolster OpenAI's capabilities in AI-driven software development and to compete more effectively with other players in the space, such as GitHub Copilot and Amazon CodeWhisperer.
