What Cognition reported in September 2025
Cognition linked its funding announcement to Devin revenue growth and its acquisition of Windsurf.
Originally posted · Published here · 1 source · Resume reading
Cognition announced more than $400 million in funding at a $10.2 billion post-money valuation on 2025-09-08. Founders Fund led the round. These figures describe that financing, rather than the company's current value. [1]
Keep the revenue periods clear
The company said Devin's annual recurring revenue increased from $1 million in September 2024 to $73 million in June 2025, before the Windsurf acquisition. It then described further growth after bringing the businesses together. Those are company-reported recurring revenue measures, not a statement of profit. [1]
What the product strategy meant
Cognition described investing in both an IDE and an agent: an editor for making decisions interactively, and a separate workflow for delegating tasks. [1]
For a developer, the choice depends on the task. A small change with unclear requirements may need close iteration. A well-specified task can be delegated with clear acceptance checks. In either case, review the resulting code and its tests before merging.
