Wispr, the company behind voice input software Wispr Flow, closed a $280M Series B round led by Menlo Ventures, reaching a $2B valuation. Originally developing neural signal headphones, the company pivoted to focus on the Wispr Flow app, which allows users to dictate text directly to their cursor via hotkeys, emphasizing a "zero-edit" experience. In August 2026, Wispr launched its proprietary voice model Canto, significantly reducing word error rates. The product boasts 60 billion words input, an 80% user retention rate, and adoption by 270 Fortune 500 companies, alongside a new AI meeting assistant, Notetaker.
