Wispr Flow Secures $25 Million in Funding, Reaching $700 Million Valuation for Voice AI Innovation

San Francisco, CA – Wispr Flow, a pioneering voice AI company, has announced a significant $25 million Series A extension led by Notable Capital, pushing its post-money valuation to an impressive $700 million. This latest investment brings the company's total funding to $81 million, aimed at advancing its mission to revolutionize human-technology interaction through voice. The funding round also saw participation from Steven Bartlett's Flight Fund.

The company, co-founded by Tanay Kothari and Sahaj Garg, is rapidly gaining traction with its Wispr Flow dictation app. According to company statements, an average user writes over 50% of their characters through the app after three months of usage, demonstrating strong engagement. Wispr Flow has also penetrated the enterprise market, serving 270 Fortune 500 companies and adding 125 new enterprise customers weekly.

Notable Capital, an investor in companies such as Affirm and Airbnb, expressed strong conviction in Wispr Flow's potential. As shared by Notable Capital on social media, "What @tankots and @SahajGarg6 have built is rethinking how humans interact with technology. They're working with customers like Clay, Perplexity, OpenAI, Replit & Superhuman and have an ambitious vision for the future of voice." Hans Tung, Managing Partner at Notable Capital, will join Wispr's board as an observer.

Wispr Flow's CEO, Tanay Kothari, highlighted the company's remarkable growth, reporting a 40% month-on-month increase since June. The company aims to move beyond simple transcription to achieve "actual understanding," with its technology reportedly boasting a significantly lower error rate compared to competitors like OpenAI's Whisper and Apple's native transcription. This focus on accuracy allows users to trust the system implicitly.

Looking ahead, Wispr Flow plans to leverage the new capital for international expansion, develop new product features, and attract top machine learning talent. The company is also working on an Android application, with a beta version expected by year-end and a stable release in Q1 2025. Notable Capital's Tung emphasized Wispr's potential to evolve into a "voice-led operating system" that initiates workflow automation, reflecting the founders' long-standing vision for a more intuitive human-computer interface.
