Cognition AI
Cognition AI is the company behind Devin, the world's first fully autonomous AI software engineer capable of planning and executing complex multi-step engineering tasks end-to-end in a sandboxed environment. Founded in 2023 by competitive programming champions, the company raised a $175M Series B at a $2 billion valuation in 2024. In December 2025, Cognition acquired Windsurf IDE for approximately $250 million, expanding its footprint in the agentic coding space.

Devin Review is an AI-powered code review feature from Cognition AI that deploys the Devin AI software engineer to autonomously review pull requests, identify bugs, flag security issues, and provide actionable inline suggestions. It integrates natively with GitHub workflows, allowing engineering teams to receive thorough, context-aware code reviews without blocking on human reviewers. It is part of the broader Devin platform, which positions itself as a fully autonomous AI software engineer.
codingWindsurf is an agentic AI-first IDE originally built by Codeium (formerly Exafunction), featuring the Cascade agentic AI system that can autonomously plan, edit, and execute multi-file coding tasks with deep codebase awareness. It ships a proprietary coding model (SWE-1.5) optimized for software engineering tasks and competes directly with Cursor as one of the leading AI code editors. Codeium/Windsurf was acquired by Cognition AI (makers of Devin) for approximately $250M in December 2025.
