Wispr Flow raises $280M at $2B valuation

Wispr Flow, a San Francisco-based AI dictation startup, announced on August 17, 2026 that it raised $280 million in a Series B funding round, valuing the company at $2 billion. The round was led by existing investor Menlo Ventures, with participation from Notable Capital, New Enterprise Associates, Neon, 8VC, MVP Ventures, and new investors including Acrew Capital, Forerunner Ventures, Goodwater Capital, Peak XV Partners, Together Fund, and PLUS Capital. The company also attracted investments from several athletes and cultural figures. This funding brings Wispr Flow's total capital raised to $361 million, nearly tripling its valuation from $700 million in November 2025. The company plans to use the funds to improve its speech recognition technology and expand its enterprise business. Alongside the funding, Wispr Flow previewed Canto, its first proprietary speech-recognition model, which the company claims reduces error rates in difficult conditions from over 30% to between 5% and 10%. Wispr Flow's products are used by over 10,000 enterprises and nearly all Fortune 500 companies, with users generating over 60 billion words. The funding reflects strong investor enthusiasm for AI voice technology, though some analysts caution about sustaining high growth rates.
