Wispr Raises $25 Million to Build Its Voice Operating System

Wispr, a voice-to-text systems provider, has raised $25 million from Notable Capital and Flight Fund just months after a $30 million Series A funding round and total funding of $81 million.

Wispr is building its own voice-first foundation models as the basis of an operating system that makes speech the primary way people interact with technology. The vision goes beyond traditional dictation tools and forms the early layers of a voice-native computing system.

"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," said Tanay Kothari, co-founder and CEO of Wispr, in a statement. "We're building a system designed to make speech a primary mode of computing so that people can work at the speed of thought, on any platform. The strong inbound interest from investors just a few short months since our last raise shows how powerful this vision has become and gives us the ability to scale it faster."

"Wispr is tackling one of the most ambitious challenges in technology: reimagining the primary interface between humans and machines," said Hans Tung, managing partner of Notable Capital, in a statement. "The founders' vision, speed, and craftsmanship stand out even among the best teams we've seen. My colleague Chelcie Taylor and I believe Wispr is building the foundation for a new generation of AI-driven interfaces, and we're proud to partner with them in that mission."

Entrepreneur Steven Bartlett, host of the Diary of a CEO podcast and principal investor in Flight Fund, said "Voice is the natural interface for human thought, but we've accepted typing because it was the only option. Now, with AI able to understand the nuance in how each of us speaks and thinks, we can finally remove that bottleneck. Wispr's founders recognized what the market is only now beginning to see: that voice will reshape how we interact with technology. The caliber of critical thinking and technical prowess behind Flow is exactly what I look for: a team that sees where the world is heading and has the depth not only to build it, but to completely redefine how we all work in the process."
