Wispr has raised $25 million in a Series A extension just five months after closing a $30 million Series A led by Menlo Ventures .
The voice-to-text AI company, which has 40% month-over-month growth, brought in the new capital from Notable Capital , the firm behind early investments in Airbnb , Slack , Coinbase , Anthropic , and TikTok .
With this round, Wispr has now raised $81 million total and sits at a $700 million post-money valuation. Wispr Flow, the company's voice dictation app, is actually working. Users aren't just trying it once. They're using it for the majority of their typing.
After six months, the average user writes 72% of their characters through Flow. That's a substitution where typing is being replaced. For decades, voice-to-text has been a broken promise. Apple's Siri struggles with accuracy. Google's Recorder requires extensive manual editing.
Amazon's Alexa can't handle real-time transcription without errors. The fundamental problem isn't transcription. The problem is polish. The voice is messy, people speak in fragments, with filler words, without punctuation, with natural hesitations.
Converting raw speech into publishable text requires intelligence, not just accuracy. Wispr solved it. Flow removes filler words automatically, adds proper punctuation, formats text based on context (an email looks different than a Slack message), and maintains consistency across 25,000 apps and websites.
Most importantly, 90% of what users dictate requires zero edits, compared to 10% for Siri and 73% error rate for Apple's native transcription. "Voice never reached its potential because the industry treated it as a feature instead of an interface.
We're picking up where others left off, and the growing migration of users to Wispr reinforces how much demand there is for a dependable voice interface," CEO Tanay Kothari said. The Metrics That Matter The numbers paint a picture of real product-market fit.
