Aug 17 (Reuters) – AI startup Wispr Flow has nearly tripled its valuation to $2 billion in nine months, underscoring investor enthusiasm for voice tools that ​let users work and write hands-free.

The AI dictation ‌company said on Monday it has raised $280 million in a Series B round, led by existing investor Menlo Ventures and including current backers Notable Capital, NEA and Neo Ventures. New investors included Acrew, Forerunner, ‌Goodwater ​and Peak XV.

The San Francisco-based Wispr ⁠had raised $25 million in ⁠a Series A extension round in November last year at a $700 million valuation. The total funding has now reached $361 million.

Global venture capital is flowing increasingly toward AI, ​robotics and chip startups, fueling a surge in billion-dollar companies, faster follow-on rounds and sharply higher valuations for ⁠a select group of high-growth firms.

Wispr ⁠Flow, whose software converts speech into text ​for writing and workplace tasks, said its products are used ​at more than 10,000 enterprises.

“The value may be there ‌if the growth rate survives, since triple digit quarterly growth off a small base is the easiest number in venture capital to generate for a few quarters and ⁠the hardest one to keep producing once the early adopters stop being the entire customer base,” said Michael Ashley Schulman, partner ⁠at Cerity Partners.

The ‌company on Monday also unveiled a preview ⁠of Canto, its first proprietary speech-recognition model.

“We ​built this ‌model for where people actually use Flow. ​In the ⁠hardest conditions, with background noise, wind, heavy accents or music, error rates fall from more than 30% of words to somewhere between 5% and 10%,” CEO Tanay Kothari said in a blog post.
