  Wispr raised a $280 million Series B at a $2 billion valuation (announced August 17, 2026), led by Menlo Ventures, bringing total funding to $361 million

  Bloomberg reported the $2B talks in May 2026; TechCrunch confirms the round closed in August 2026 at that valuation.

  Wispr Flow has been adopted at 270 Fortune 500 companies and was signing 125 new enterprise customers per week with no outbound sales motion (as of the November 2025 Series A extension)

  Figures are as of Nov 2025; no updated Fortune 500 count was found alongside the Aug 2026 raise.

  Wispr was founded in 2021 by Tanay Kothari and Sahaj Garg, originally building a brain-computer interface before pivoting to the Wispr Flow voice dictation app around 2024

  Founder Tanay Kothari's own X post corroborates the founding timeline and the BCI-to-Flow pivot at year 3.

  Wispr Flow generates roughly $10M in ARR

  Single third-party estimator; conflicts with a separate figure of approximately $3.8M in revenue for July 2024 to July 2025 cited on Wikipedia, and with other industry estimates in the $15-35M range. Wispr does not disclose revenue.

  Wispr Flow's model has roughly a 10% word error rate versus 27% for OpenAI Whisper and 47% for Apple's native transcription, and the new 'Canto' model cuts errors from 30% to under 10%

  Both figures are self-reported by the company via TechCrunch; no independently run benchmark was found.

  40% month-over-month growth, 100x user base growth year-over-year, and 70% retention over 12 months (as of Nov 2025)

  Self-reported growth metrics, not independently audited. A separate Wikipedia-cited dataset instead lists 80% six-month active-user retention and 50%+ monthly user growth, an inconsistent figure from a different source and period.
