Wispr Raises $280M Series B at $2B Valuation as It Moves Beyond Dictation

The funding will back Canto, Wispr’s first in‑house speech model aimed at sharply lowering real‑world transcription errors and broadening meeting and interface products.

Overview

  • Wispr announced the $280 million Series B on Monday, Aug. 17, which Menlo Ventures led and which brought the company’s total funding to $361 million.
  • The company previewed Canto, its proprietary speech‑recognition model, saying it cuts word error rates in noisy, accented, or music‑filled settings from over 30% to roughly 5–10%.
  • Wispr said much of the new capital will go to improving transcription accuracy using a “zero edit rate” target, expanding its Notetaker meeting product, and scaling integrations with enterprise software and hardware partners.
  • Company‑reported adoption metrics frame the push: users have generated more than 60 billion words, Flow is used at most Fortune 500 firms and over 125,000 businesses, and the app has millions of downloads and hundreds of thousands of daily users.
  • The round strengthens Wispr’s position in a crowded voice‑AI field but raises practical questions for enterprises about accuracy, workflow integration, and meeting privacy and consent as always‑on transcription spreads.
