Voice AI startup Wispr has raised an additional $25 million to accelerate its ambition of building a voice-native operating system for work. The new capital comes barely four months after its $30 million Series A round, underscoring growing investor conviction in speech as the next major computing interface. With this extension, Wispr’s total funding reaches $81 million and strengthens its position in the fast-growing voice dictation and productivity market.
New Funding and Investor Lineup
The latest round is led by Notable Capital, with participation from Steven Bartlett’s Flight Fund. Notable Capital partner Hans Tung, a 13-time Forbes Midas List investor known for early bets on companies such as Affirm, Airbnb, Slack, Coinbase, Anthropic, and TikTok, joins Wispr’s board as an observer. His involvement signals a belief that Wispr can turn voice computing into an everyday habit at similar scale to his previous portfolio successes.
Building a Voice-Native Operating System
Wispr, led by CEO and co-founder Tanay Kothari, is not positioning its Wispr Flow product as a simple dictation layer on top of existing tools. The company is developing its own voice-first foundation models and infrastructure so speech can reliably function as a primary interface rather than a convenient add-on. By controlling the full stack instead of relying solely on general-purpose language models, Wispr aims to deliver faster responses, higher consistency, and behavior that feels the same across applications.
Traction With Enterprises and Knowledge Workers
Wispr Flow is seeing rapid uptake among individual professionals and large organizations as people increasingly adopt voice for real work instead of treating it as a novelty. After a few months of usage, average users now write more than half of their characters by voice, and internal metrics show Flow can be several times faster than typing for many tasks. The company reports that it has already reached hundreds of large enterprises and signed more than one hundred organizations as customers, pointing to strong early product-market fit.
Enterprise Push and Hiring Plans
Engineering teams have emerged as prominent early adopters, using Flow inside integrated development environments to code by voice while maintaining focus. At the same time, Wispr highlights adoption among people with conditions such as Parkinson’s disease, arthritis, or age-related mobility and vision challenges, for whom long hours at a keyboard are difficult or impossible. The company is also investing in new pricing, team features, and enterprise-grade security so organizations can roll out voice driven workflows safely at scale.
With this new funding, Wispr is intensifying its efforts to build a comprehensive voice-native computing system and the models that power it. The company is hiring across AI infrastructure, speech modeling, latency engineering, and personalization as it works toward a future where voice becomes the primary interface for work. Backing from Notable Capital, Hans Tung, and Steven Bartlett’s Flight Fund gives Wispr financial firepower, strategic guidance, and cultural reach as it pushes toward a post-keyboard world.
