Cognition, the company behind the autonomous AI software engineer Devin, just closed over $1 billion in Series D funding at a $26 billion post-money valuation. That number alone would be headline-worthy, but the story underneath it is what makes this round remarkable: in 12 months, Cognition grew its annualized revenue run-rate from $37 million to $492 million, a 1,230% increase, while its own engineering team handed 89% of their code commits over to the very product they are building.

This is not a bet on future potential. It is a bet on a company that has already found product-market fit at rocket-ship scale.

The numbers behind the valuation

The $26B post-money figure is a major leap from Cognition's $10.2 billion post-money valuation when it closed a $400 million round just eight months ago in September. The company has now raised more than $2.5 billion in total funding. At this valuation, Cognition is priced at roughly 53 times revenue , aggressive by any standard, but hard to argue with when enterprise usage has grown more than 10x in a single year.

Enterprise usage of Devin has grown 50% month-over-month for the past six months. The company says it aims to cross $1 billion in annualized revenue later this year. For context, AI-native enterprise spending surged 94% year on year in early 2026 while traditional SaaS growth cooled to 8%.

Who is behind the round

The round was led by Lux Capital, General Catalyst, and 8VC, with support from existing investors including Founders Fund, Elad Gil, Alpha Wave, Definition Capital, Positive Sum, Avenir, Vitruvian, Bain Capital Ventures, Conversion Capital, 137 Ventures, Soma Capital, and Omri Casspi. New investors include Ribbit Capital, Atreides, and Layer Global.

Cognition was founded in November 2023 by Scott Wu (CEO), Steven Hao (CTO), and Walden Yan (CPO). Wu told Bloomberg the raise "allows us to stay independent and continue as an independent business, which is really important for us." That comment about independence is pointed, and intentional.

What Devin actually does

Cognition's flagship product is Devin, an AI agent designed to automate the programming process end-to-end. Unlike code completion tools that suggest lines or blocks of code while a human developer writes, Devin operates as a full coding agent that can take a task description and produce working software autonomously. It plans, writes, debugs, and deploys code across complex multi-step workflows. Think of it as assigning a ticket to a teammate who never needs to ask for clarification on the basics.
