Whisp Flow, a voice-powered AI platform used by nearly all Fortune 500 companies and over 10,000 other enterprises, announced $280 million in Series B funding at a $2 billion valuation.

Led by Menlo Ventures with participation from new and existing investors, the company has raised a total of $361 million to date.

Reporting ~40x year-over-year revenue growth to over $100M, Whisp Flow has processed over 60 billion dictated words.
