Cognition Hits $48B, Nearly Double Its May Valuation

Cognition, the startup behind the autonomous software engineer Devin, has raised more than $2 billion in a Series E at a $48 billion post-money valuation, announced on September 8. Andreessen Horowitz and Accel led as new investors, joined by existing backers Founders Fund, General Catalyst and Avenir, alongside a wide syndicate including Benchmark, Bessemer, Kleiner Perkins, Greylock, Lightspeed, T. Rowe Price, Lux Capital and Nvidia.

The pace is the story. BitsMinds covered the $1 billion Series D at $26 billion in May, and reported talks at $40 billion in August. The closed round prices roughly 85% above the May mark in about four months, and it lands above the number that leaked three weeks earlier — the same pattern as the Series D, which also cleared its own rumoured price.

Unlike a lot of 2026 AI marks, this one has revenue moving underneath it. Run-rate revenue has gone from roughly $492 million at the Series D to close to $900 million now, nearly doubling on the same four-month clock as the valuation. That still leaves the company trading at something like 53 times run-rate — expensive by any conventional software standard, though the growth rate is what investors are underwriting rather than the multiple.

Devin's positioning explains some of the enthusiasm. Where GitHub Copilot and Cursor sit alongside a human in the editor, Devin is sold as a standalone agent that takes a ticket, opens a branch and returns a pull request. That framing puts Cognition on the far end of the autonomy spectrum, and it means the company is priced against services budgets rather than seat licences — a much larger pool, and a much harder promise to keep.

The customer list has broadened accordingly. Cognition names the US Army and Navy, NASA, ServiceNow, Infosys and Goldman Sachs among its users — a mix that skews toward large regulated buyers with substantial legacy codebases, which is where agent-written pull requests are simultaneously most valuable and most closely reviewed.

Founded in 2023, Cognition launched Devin in March 2024 to a wave of scepticism about demo-versus-reality, absorbed what was left of IDE startup Windsurf after its leadership was picked off in 2025, and has now repriced itself four times in roughly a year. At $48 billion it is worth more than double Mistral's freshly minted €21 billion, despite building no foundation model of its own and running its agents on other labs' weights.

That dependency is the open question the round does not answer. Cognition's margins and capabilities both sit downstream of model providers whose own coding agents — Claude Code, Codex, Jules — compete directly for the same budget. Nvidia's presence on the cap table hedges the compute side; nothing on this list hedges the model side.
