Devin ARR is hiting $70M-80M

Cognition, the San Francisco–based AI startup behind Devin, recently announced the acquisition of Windsurf, an AI-native integrated development environment (IDE), adding its standalone business and IP to Cognition’s offerings.

According to a conversation between Scott Wu and 20VC, Devin is doing $70M-80M Run-Rate, up 5-10x since January. Including Windsurf, the combined company is likely at ~$150M+ run-rate revenue now!

The core product, Devin, is a fully autonomous AI software engineer capable of planning, coding, debugging, deploying, and self-learning within a sandboxed environment—essentially acting as a junior developer on real-world software tasks.

By integrating Windsurf’s IDE, Cognition now delivers a seamless agentic coding experience, combining Devin’s autonomous capabilities with Windsurf’s developer-friendly interface—a pairing ideal for enterprises looking to automate software delivery at scale and reduce dependency on human coders.

Cognition has seen a meteoric rise in valuation and funding: backed by Founders Fund, Khosla Ventures, 8VC, and others, it reached a $4 billion valuation in Q2 2025 after raising ~$175 million in its Series B, following a Series A of $21 million led by Founders Fund in early 2024.

With ARR surging 5–10× since January and enterprise customers doubling quarter over quarter, Cognition is scaling quickly—hiring ex-Windsurf engineers with full equity participation—to cement its status as a leading player in the booming AI-driven software engineering market.
