Details of the round

Wispr, known for the AI-powered dictation app Wispr Flow, raised $280 million in Series B funding at a $2 billion valuation. The round was led by Menlo Ventures.

The participants fall into two groups:

  • Existing investors: Notable Capital, NEA, Neo Ventures, 8VC and MVP Ventures doubled down.
  • New investors: Acrew, Forerunner, Goodwater, Peak XV, Together Fund and PLUS Capital.

With this round the company has raised $361 million to date.

The jump in valuation

What makes the figure notable is the speed. When Wispr raised $25 million in November 2025, it was valued at $700 million. The valuation nearly tripling in under a year shows investor appetite for voice-based AI tools. The company's previous round was less than 10 months before this one.

Revenue appears to support that interest: according to information shared, Wispr's revenue grew more than 150 percent in each of the last four quarters.

The company's history

Wispr was founded in 2021 by Tanay Kothari and Sahaj Garg. The original idea was quite different from today's: the company was working on hardware that would let users enter text into devices by mouthing words silently. The focus later shifted to dictation on the software side.

Competition and a quality problem

The new capital arrives as competition in dictation increases. As TechCrunch reports, apps such as Willow, Monologue, Aqua and Superwhisper compete in the same space, and several developers are creating free or lower-priced tools for prosumers.

Alongside the funding news the company announced a new model to improve the quality of speech understanding. There is a reason for it: for the last few weeks several users had complained about a quality dip in Wispr Flow's dictation output. The company says its new model, called Canto, will reduce error rates from 30 percent to less than 10 percent.

How to read it

The underlying question is whether a dictation app is a defensible business on its own. Turning speech into text is an increasingly commoditised capability, and operating systems offer the same function for free. The company moving into new areas with a meeting note-taker suggests it is aware of that pressure.

The second point is that the quality dip was addressed in the same breath as the announcement. Acknowledging a 30 percent error rate and stating a target below 10 percent means the company accepts the product had degraded in users' eyes. Whether the new model meets that claim will matter more than the funding itself. It should also be noted that the figures rest on company statements, with no independent measurement.
