Wispr raises $280M led by Menlo Ventures at a $2B valuation
Menlo Ventures led a $280 million equity Series B into Wispr at a $2 billion valuation, less than ten months after a $25 million round. The company shipped a new speech model, Canto, after users complained dictation quality had slipped.

Menlo Ventures led a $280 million Series B into Wispr, the voice dictation company, at a $2 billion valuation. This is equity, not debt. TechCrunch and Fortune both reported the round.
The step up is from a $25M round, not a named valuation
The number worth holding onto is the one underneath the headline. Wispr's previous round was $25 million, from Notable Capital, closed less than ten months ago. The new round is 11 times that entire prior raise.
Neither story names the prior valuation, so anyone quoting a specific multiple on the price is filling in a blank. What is on the record is the capital structure: $361 million raised in total across the company's life, against a $2 billion valuation. Paid-in capital is therefore about 18% of the current price, which for a four-round company at this valuation is a comparatively low dilution profile and tells you the earlier rounds were small and the growth came fast.
Existing backers Notable Capital, NEA, Neo Ventures, 8VC and MVP Ventures all put in again. New money came from Acrew, Forerunner, Goodwater, Peak XV, Together Fund and PLUS Capital. A group of athletes also invested, including Joe Burrow, Shaun White, Klay Thompson and Paul George.
Canto exists because the product got worse
Here is the fact that did not make anyone's headline. Wispr shipped a new speech understanding model called Canto, and TechCrunch reports it cuts the error rate from 30% to less than 10%. That is a roughly two-thirds reduction, and it takes dictation from one wrong word in three to fewer than one in ten.
The reason it shipped matters more than the number. Canto is a response to recent user complaints that dictation quality had declined. A company raising at $2 billion on the strength of its core feature had a live quality regression in that feature, and the new model is the fix. Read the funding and the model release as one event rather than two.
An error rate of "less than 10%" is also still an error rate. At one wrong word in ten, dictation remains a draft-generating tool that needs a read-through, not a hands-off transcription layer. That gap is precisely the space between the product today and the ambient-computing story the round is priced on.
What the money is for, and what it is not
Wispr's stated plan is to move beyond dictation:
- Meetings, via a newly released notetaker, which puts it into a crowded category rather than an open one.
- Go-to-market expansion in India and the UK.
- Hardware partnerships, including the Oasis ring.
- Interface Labs, an exploratory effort.
Products today are Wispr Flow, the dictation app, now on Android, plus the notetaker.
On traction, Fortune reports revenue growing north of 150% for four consecutive quarters and a base of millions of consumers and 100,000 businesses. Sustained 150%-plus growth implies revenue roughly two and a half times where it stood a year ago. No absolute revenue figure was disclosed, so the $2 billion valuation cannot be checked against a multiple. Growth rate without a base is a direction, not a size.
The competitive set the company names is not a list of startups. It is Apple, Google, Microsoft, Anthropic and OpenAI, every one of which ships or is building voice input as a feature rather than a product.
Co-founder Sahaj Garg put the defensibility argument on privacy: "Privacy and security aren't features for us: They're the foundation for earning ambient access to your life." On how far the automation should go, Garg drew a line: "These systems can consult for you, but you should still supply your intent." Co-founder Tanay Kothari framed the origin: "When Sahaj and I were talking about the biggest problems we wanted to solve, one of the things that came up was what it means to have a world where AI is prevalent."
The takeaway
Judge this one on retention, not on the raise. The Canto release tells you Wispr already had a quality regression severe enough for users to notice and complain, in the single feature the company is valued for. The question for the next two quarters is whether the 150%-plus growth rate holds now that the fix has shipped, or whether some of that growth was booked before the regression and has churn behind it. Ask for net revenue retention on the 100,000 business accounts. That number, not the $2 billion, tells you whether dictation is a habit or a trial.
