- Wispr raised $280 million at a $2 billion valuation.
- Canto is a preview, not a fully documented public benchmark.
- Flow now spans dictation, meeting notes and speech-model research.
Wispr has raised $280 million in a Series B led by Menlo Ventures. The private financing values the voice-software maker at $2 billion. Wispr also previewed Canto, its first proprietary speech model.
The deal gives Wispr far more capital to improve dictation accuracy. It also raises the commercial bar. The valuation is almost three times the $700 million figure reported nine months ago.
For users, the useful test is simpler. Canto must reduce corrections enough to justify another paid tool. Built-in dictation is free, while Flow Pro costs $15 monthly.
| Financing milestone | New capital | Total raised | Valuation | Status |
|---|---|---|---|---|
| June 2025 Series A | $30 million | $56 million | Not disclosed | Company announced |
| November 2025 follow-on | $25 million | $81 million | $700 million | Reported post-money |
| August 2026 Series B | $280 million | $361 million | $2 billion | Company announced |
The Series B is 11.2 times larger than Wispr’s previous disclosed round. Its valuation has increased about 186% since November. The latest investor group includes existing backers and several new funds.
Chief Executive Tanay Kothari said accuracy determines whether voice becomes a daily interface. “The whole reason to talk instead of type is to stay inside your own train of thought,” he wrote.
| Canto measure | Earlier result | Canto claim | What is known |
|---|---|---|---|
| Word error rate in hardest conditions | More than 30% | 5%–10% | Company test; background noise, wind, music or heavy accents |
| Dictations needing edits in everyday use | Baseline not published | 30%–35% reduction | Company expectation |
| Model availability | Existing Flow models | Preview | General rollout date not stated |
| Personal context | Not comparable | Uses dictionaries and nearby names | Company description |
The largest claimed gains appear under difficult acoustic conditions. That matters on phones, where cars, streets and offices create poor recordings. Wispr has not published an independent evaluation or a full test set.
| Flow plan | Price | Usage | Selected controls |
|---|---|---|---|
| Basic | Free | 2,000 words weekly on desktop; 1,000 on iPhone; unlimited Android use is temporary | Privacy Mode; custom dictionary; 100+ languages |
| Student | $0 annually for eligible students | Unlimited dictation | Claimed on desktop or web |
| Pro | $15 per user monthly; about $12 monthly on annual billing | Unlimited across supported platforms | Command Mode; priority support; early features |
| Enterprise | Contact sales | Unlimited | SSO/SAML; enforced policies; advanced dashboards |
The same speech engine serves every paid tier, according to Wispr. That makes limits, management and security the main price differences. The company supports Mac, Windows, iPhone and Android.
| Product or initiative | Date | Status | Primary job |
|---|---|---|---|
| Flow Dictation | Current | Available | Turns speech into edited text across apps |
| Flow Notetaker | August 5, 2026 | Launched | Creates meeting notes, summaries and action items |
| Canto | August 17, 2026 | Previewed | Improves speech recognition in real conditions |
| Advanced Interfaces Lab | July 24, 2026 | Operating | Researches voice-led human-computer interaction |
Wispr is also moving beyond dictation. Its Notetaker product entered the meeting market this month. The Advanced Interfaces Lab is researching systems that convert speech into actions, not only text.
Scale gives that expansion a base. Wispr says Flow users have produced more than 60 billion words. It also claims use across more than 10,000 enterprises and almost all Fortune 500 companies. Those figures have not been independently audited.
Privacy remains central for business adoption. Wispr says Privacy Mode prevents dictation data from training its models. It lists SOC 2 Type II, ISO 27001 and HIPAA-related controls, with enforcement varying by plan.
Risks: Canto is still a preview, and its performance numbers come from Wispr. The company discloses no revenue in the announcement. A richer valuation therefore rests on product adoption, retention and model gains that outsiders cannot yet verify.
The financing buys Wispr time to prove those gains at scale. The next evidence should come from public benchmarks, broad Canto availability and measurable reductions in user corrections.
