Speech AI Startup Wispr Lands $25M Boost Amid Explosive Growth
Wispr's Voice Tech Gains Momentum With Major Funding Round
Speech recognition startup Wispr announced today it has raised $25 million in Series B+ funding, bringing its total investment to $81 million. Notable Capital led the round, with participation from Steven Bartlett's Flight Fund.

Rapid Adoption Across Enterprises
The company revealed impressive traction for its Flow Dictation product. Within just three months of launch, voice input accounted for an average of 50% of characters typed across user bases. Perhaps more striking is Wispr's enterprise adoption - their client roster now includes 270 Fortune 500 companies and 125 paying institutions.
"We're seeing tremendous organic growth," a company spokesperson noted. "When executives experience how seamlessly our technology integrates into their workflow, they become instant advocates."
By The Numbers: Wispr's Growth Metrics
The funding announcement came packed with notable statistics:
- User retention: Maintaining an impressive 70% retention rate after one year
- Monthly growth: Consistently hitting 40% monthly growth since June
- Accuracy edge: Their proprietary speech recognition shows just a 10% error rate - significantly better than competitors like OpenAI Whisper (27%) and Apple (47%)
The company isn't resting on these achievements though. Engineers are already working to push the error rate below 5%, which could revolutionize voice-to-text applications.

Expansion Plans Take Shape
The fresh capital will fuel several strategic initiatives:
- Recruiting top machine learning talent worldwide
- Expanding international operations teams
- Opening API access to third-party developers
The roadmap includes ambitious platform expansions too. While Windows, Mac and iOS versions are already available, Android users can expect a beta release by year's end with full rollout planned for early 2026. Development is also underway for Windows on ARM and iPad versions.
Hans Tung from Notable Capital joined Wispr's board as part of the deal. He sees parallels between Wispr's trajectory and other breakout tech successes: "The user experience creates natural network effects - we're seeing that 'aha moment' reminiscent of Airbnb's early days."
The company hints at evolving beyond simple dictation tools toward becoming a comprehensive "voice-first operating system." Early tests include voice-driven workflows like email responses and form completion - features that could fundamentally change how we interact with computers.
Key Points:
- $25M Series B+ brings total funding to $81M
- 100x user growth year-over-year with strong retention
- 10% error rate beats major competitors' speech recognition
- Global expansion planned across platforms and markets
- Voice OS vision aims beyond basic dictation functionality
