Wispr raises $280M Series B at $2B valuation, moves beyond dictation

Its wager is that voice becomes the default interface for software, not just a faster way to type words.

• Wispr raised $280 million in a Series B led by Menlo Ventures at a $2 billion valuation, arriving just six months after its Series A2.
• Wispr makes Flow, an AI dictation app now used by employees at most Fortune 500 companies and across more than 125,000 businesses.
• Alongside the raise, Wispr unveiled Canto, its first proprietary speech model, built inside a new Advanced Interfaces Lab led by chief scientist Ariya Rastrow, a former Amazon Alexa founding member and Meta multimodal lead.
• Canto is built to cut word error rates from over 30% to roughly 5-10% under tough conditions like background noise, wind or strong accents.
• Revenue has grown more than 150% in each of the past four quarters, and total capital raised now stands at $361 million.
• The round lands amid intensifying competition in dictation from rivals like Willow, Monologue, Aqua and Superwhisper, plus cheaper prosumer alternatives.
• A $2 billion price on a dictation app signals investors betting voice becomes the ambient interface layer above productivity software, contesting ground long held by keyboards and by Apple, Google and Microsoft's own voice efforts.
