Cognition is an applied AI lab that builds autonomous software engineering agents. Its flagship product, Devin, takes a plain-language task description and executes the entire software development lifecycle end-to-end — planning architecture, writing code, running tests, debugging failures, and shipping a pull request — without a human in the loop at each step. It integrates directly into existing tools like Slack, GitHub, and Linear, and can be deployed as SaaS or inside a customer's private cloud. After acquiring Windsurf in July 2025, Cognition also offers an AI-native IDE with agentic workflows baked in. Buyers are enterprise engineering teams at large banks, automakers, government agencies, and Fortune 500 companies who want to compress software delivery cycles by delegating whole tasks to AI rather than just autocompleting lines. Cognition internally eats its own dog food: 89% of code committed at the company is now written by Devin itself.
