Wispr Flow, the voice-to-text dictation platform, raised $280 million in Series B funding at a $2 billion valuation, led by Menlo Ventures. The round includes existing investors Notable Capital, NEA, Neo Ventures, 8VC, and MVP Ventures, as well as new backers Acrew, Forerunner, Goodwater, Peak XV, Together Fund, and PLUS Capital. Notable athletes including Joe Burrow, Shaun White, Klay Thompson, DK Metcalf, and others also participated. Total capital raised to date is $361 million.
Wispr Flow reported 60+ billion words generated on its platform and adoption across nearly all Fortune 500 companies and more than 10,000 enterprises. The company has achieved 150%+ quarterly revenue growth for four straight quarters. The round caps a nine-month acceleration: Wispr raised $25 million in November 2025 and now commands a $2 billion valuation. Alongside the funding, Wispr unveiled Canto, its first proprietary speech-recognition model designed for real-world acoustic conditions with error rates dropping from over 30% to 5-10% in noisy environments.
Wispr Flow is expanding beyond dictation into meeting notetaking with its Notetaker tool (launched last week) and new meeting transcription features. The company established the Wispr Advanced Interfaces Lab, led by Alexa founding engineer Ariya Rastrow, to explore next-generation voice interfaces and ambient computing. Menlo partner Matt Kraning positioned the company's ambition: 'Dictation is how you get in the door. What people pay for is not having to type, which puts you up against workflow tools, meeting tools, and eventually the text box in front of every AI model.'
For workforce productivity leaders, Wispr Flow's enterprise penetration and revenue growth signal voice-as-interface is moving into mainstream work tools. The company faces competition from Apple, Google, Microsoft, Anthropic, and OpenAI on voice, plus crowded dictation apps (Willow, Monologue, Aqua, Superwhisper). Wispr's defensibility rests on proprietary Canto models, Fortune 500 relationships, and hands-free workflow integration. Buyers should evaluate zero-edit-rate metrics, latency in noisy conditions, and hardware partnership roadmaps (e.g., Oasis ring integration).
