Devin (Cognition)
🟢ActiveCognition unveiled Devin in March 2024 as 'the first AI software engineer', capable of taking a Linear ticket and shipping a pull request end-to-end. Independent reviewers (notably Carl Brown's analysis) showed the launch demo was carefully edited and that real-world success rates were modest. Cognition kept iterating and acquired Windsurf in July 2025 to give Devin a real IDE surface. The company's valuation reached $4B+ in 2025 funding rounds.
