Devin Maker Cognition Closes $1B Series D at a $26B Valuation, More Than Doubling in Eight Months

Cognition, the startup behind the autonomous software engineer Devin, has closed a Series D of more than $1 billion at a post-money valuation of $26 billion, the company confirmed on May 27. The round was co-led by Lux Capital, General Catalyst and 8VC, with existing investors including Founders Fund, Soma Capital, Elad Gil and Omri Casspi joined by new backers Ribbit Capital, Atreides Management and Layer Global, according to Bloomberg and TechCrunch.

The price is striking even by 2026 standards. Cognition was valued at $10.2 billion in September 2025 — meaning the new round more than doubles the company in just eight months, and represents a roughly 2.5× jump for a startup that did not exist as a product until March 2024. PixelMind covered the early reporting in April, when CNBC first surfaced talks of a $25 billion mark; that the closed round priced slightly above the leak is a quiet signal of how hot the autonomous-coding category remains.

The business behind the markup is finally legible. Cognition is running at roughly $492 million in annualized revenue with enterprise customers including Goldman Sachs, Mercedes-Benz, NASA and Santander, and says enterprise usage has grown more than ten times since the start of the year. The most-quoted line in the funding pitch is also the most telling one: 89% of code committed by Cognition’s own engineers, the company says, is now written by Devin itself.

That number gets to the strategic logic. Where coding assistants like GitHub Copilot and Cursor sit beside a human developer, Devin is sold as a stand-alone agent that picks up Linear tickets, opens its own branches and ships pull requests. Earlier this year Cognition absorbed what remained of Windsurf, the IDE startup whose leadership team had been picked off by Google DeepMind, folding its agentic editor into the Devin stack. The acquisitions and the funding round push Cognition toward a single bet: that the next generation of software engineering is something you delegate to, not something you sit next to.

The competition has noticed. Anthropic ships Claude Code, OpenAI ships Codex, and Chinese open-source agents have started crowding the leaderboard. Against that field, $26 billion is less a verdict on Devin’s present capabilities than a wager that the company most willing to let an agent commit real production code will end up owning the category. With more than a billion dollars on the balance sheet and an ARR curve still steepening, Cognition now has the room to test the wager at scale.
