Cognition Closes $1 Billion-Plus Series D, Valuing It at $26 Billion

Cognition AI said it closed a $1 billion-plus Series D on May 27, 2026, valuing the company at $26 billion and more than doubling its September 2025 valuation of $10.2 billion in less than eight months.

Tech Times reported that the round was co-led by Lux Capital, General Catalyst, and 8VC, with Founders Fund, Ribbit Capital, Atreides Management, and existing investors participating.

In the same reporting, Cognition’s Devin is described as an autonomous AI software engineer that accepts a task description, executes it inside a sandboxed Linux environment, and returns a pull request for human review.

Tech Times also framed the financing as a signal that investors are betting on an “agent-first” architecture, contrasting it with IDE-first tools like Cursor built by Anysphere.

The article added that Cognition disclosed revenue growth from $37 million in May 2025 to $492 million in May 2026, alongside enterprise usage of Devin growing more than tenfold since January 2026.

SiliconANGLE said Cognition’s Series D deal values the company at $26 billion and that Cognition credited the jump to a tenfold increase in enterprise usage since the start of the year.

SiliconANGLE reported that Cognition’s flagship offering is a cloud-based AI agent called Devin, which the company said is capable of automating most programming tasks that a single developer could complete in three hours.

The same article said Devin enabled Mercedes-Benz Group AG to complete a code modernization initiative that would have normally taken eight months in eight days.

Tech Times described Devin’s workflow as spinning up an isolated virtual machine for each session with its own browser, terminal, and code editor, then proposing a pull request for human oversight at the pull request stage.

Tech Times further stated that Cognition disclosed 67% of Devin’s pull requests are now merged, up from 34% a year earlier, and that 89% of all code committed at the company itself is now written by Devin.

TechCrunch quoted Cognition CEO Scott Wu saying, “We’ve never thought about it as replacing humans,” in response to questions about whether Devin could replace a mid-level L4 programmer.

In the same TechCrunch report, Wu said, “we are shifting to a world of self-driving software development,” while insisting that “it should always be up to the human what to do.”

TechCrunch also described Devin as “naturally owns tasks end to end,” and said Cognition laid out a vision for self-driving software development in the blog post announcing the $1 billion raise.

The TechCrunch piece added that Wu said agents will free programmers “from a lot of the toil, and so they can do much more of the creation side,” and positioned Devin’s role as somewhere between a junior and a mid-level engineer depending on the task.

Separately, Tech Times reported that Cognition’s guidance is to treat Devin as a parallelizable junior engineer for tasks that can be completed in four to eight hours, verify the pull request, and scale workloads horizontally.
