Wispr, the AI-native voice productivity company behind the dictation app Wispr Flow, has secured an additional $25 million in funding following rapid commercial traction, bringing total investment to $81 million and valuing the startup at $700 million post-money. The latest round was led by Notable Capital with participation from Steven Bartlett’s Flight Fund, following Wispr’s $30 million raise announced in June. Hans Tung of Notable Capital joins the company’s board as an observer.
Wispr Flow has become a breakout workplace tool, now used inside 270 Fortune 500 companies and adding 125 new enterprise customers per week. The app has seen 40% month-over-month growth, and users now generate more than half of their typed characters through voice after three months of adoption. Wispr reports a 100x year-over-year increase in user base and 70% retention over 12 months as voice input gains foothold across professional workflows.
The new funding will accelerate hiring for machine learning and product engineering, expand Flow to new platforms including Android in early 2025, and support international rollout. Wispr is also developing proprietary personalized voice models to reduce transcription errors and automate productivity tasks such as email drafting and workflow initiation — positioning the platform as a voice-first operating layer for knowledge workers.
