The Keyboard Is Dying on Schedule. The Text Box Is Next.

Menlo Ventures is backing Wispr again, leading a $280 million Series B at a $2 billion valuation. It is a big follow-on to a company that Menlo says has already grown revenue more than 30x year over year and now has Flow running in 162 countries, over 100 languages, and with tens of thousands of paying businesses.

The firm’s bigger claim is simple: the bottleneck in AI has shifted. The models got smart first. The interface did not. Menlo argues that the text box, for all its usefulness, has become a tax on thought and productivity, especially when a person already knows what they mean but still has to type it into a machine.

That is why Menlo keeps returning to voice. Its view is not that dictation is new — far from it — but that old-school speech-to-text has stayed stuck as a feature, while Wispr is trying to become something closer to an action layer. Menlo points to what it calls “voice-to-outcome”: systems that understand intent in context and then do something useful, whether that is a workflow, an action, or a different interface altogether.

The Advanced Interfaces Lab, launched by Wispr in July and led by Ariya Rastrow as chief scientist, is part of that push. Menlo says Rastrow helped build voice AI’s first mainstream moment and then spent years seeing why it stalled at simple tasks like weather, music, and timers. The new bet is that better intelligence now makes the old speech-to-text-to-model chain look clunky.

There is also a very practical business reason for the investment. Menlo says customers are pulling Flow into new countries and languages on the consumer side, while enterprises are bringing it into team-wide and company-wide deployments without a scaled sales motion. The round is meant to fund both the sales push and the product work, while also supporting the lab that is supposed to build the next interface layer.
