Wispr is a San Francisco AI startup behind Wispr Flow, a voice-to-text dictation product used by professionals at companies including NVIDIA and Amazon. The product transcribes natural speech into polished, context-aware writing across any app, with no special syntax or commands. Founded in 2021, Wispr has built a fast-growing, viral consumer-prosumer base for voice dictation as an everyday writing input. The company is expanding beyond dictation into a broader AI voice productivity layer. Wispr raised a $25M round from Notable Capital in November 2025 at a $700M valuation, bringing total disclosed funding to $81M. In May 2026, Bloomberg and TechCrunch reported the company is in late-stage talks to raise approximately $260M in a Menlo Ventures-led Series B at a roughly $2B valuation.
