Wispr, the San Francisco company behind the Wispr Flow voice-dictation app, raised a $280m Series B at a $2bn valuation, it announced on 17 August 2026. Menlo Ventures led the round, which takes Wispr's total funding to $361m, TechCrunch reported.
Existing investors Notable Capital, NEA, Neo Ventures, 8VC and MVP Ventures took part. New investors were Acrew, Forerunner, Goodwater, Peak XV, Together Fund and PLUS Capital, TechCrunch said.
Wispr said the first and largest part of the round will go to accuracy, which it called the decider of whether voice becomes the way people live and work.
What Wispr does
Wispr Flow turns speech into edited text across apps. Wispr said its users have written more than 60 billion words with it. The company did not publish revenue, user numbers or headcount in the announcement.
The company's stated goal is a zero edit rate: dictation that needs no correcting afterwards. It said most of this round will go to research aimed at closing that gap and to getting the product into the places where people already talk and type, such as meetings.
Wispr's post argues that the main reason to speak rather than type is to stay inside one's own train of thought, which is why having to correct the text breaks the experience. It says its preview model is aimed at the noisiest conditions, where errors are most common.
A first speech model
Alongside the funding, Wispr previewed its first proprietary speech model. It said that in the noisiest conditions the model cuts word error rates from more than 30% to between 5% and 10%, and that across everyday use it expects 30% to 35% fewer dictations needing edits. These are the company's own projections, not independent measurements.
The company also has what it calls the Wispr Advanced Interfaces Lab, which Ariya Rastrow joined to lead.
Who invested
Menlo Ventures is described by Wispr as a long-time investor and partner. PLUS Capital, a new investor, brought in a group of more than 10 actors, directors and musicians and more than 10 athletes, among them Livvy Dunne, Shaun White, Dak Prescott, Joe Burrow, Klay Thompson and Trae Young.
The basketball player Domantas Sabonis, who invested through PLUS Capital, said in Wispr's post that he uses Flow every day and grew up rotating between English, Spanish and Lithuanian.
The funding so far
TechCrunch said Wispr's previous round came less than 10 months earlier. Wispr's own post links to a Series A announced the previous May but gives no amount, so this article does not state earlier round sizes.
Subtracting the new round from the total implies about $81m raised before it, though that is arithmetic from the reported figures rather than a number Wispr published.
The $2bn valuation and the $361m total both come from Wispr's announcement and TechCrunch's report. Wispr did not publish revenue or headcount.
