Today we're announcing $280M in Series B funding at a $2B valuation, led by our long-time investor and partner, Menlo Ventures. When we announced our Series A last May, most conversations I had about voice began with someone explaining why they doubted it. I don't have those conversations anymore. People tell me instead how much time they save talking instead of typing and what they want us to build next. In a little over a year, voice has gone from something people were questioning to something they rely on, and it happened faster than we expected. That shift is why we've raised a new round of funding. This funding represents a deeper investment in our products, lab, models, and our team. Alongside the funding, we're announcing a preview of our first proprietary speech model, Canto. Canto is a 2B parameter speech model trained for the places people actually talk: loud rooms, windy streets, a toddler in the background, a second language mixed into the first. Models like this will change how we all interact with devices, and Canto is the first in a rapid line of them. Each one will be larger and more capable than the last, and each should improve Flow's dictation in a way you can feel the day it ships. Larger speech models also open the door to the vision we dreamed up 5 years ago: using your voice as the primary way you interact with devices. That still has to be invented. A voice interface people rely on all day, in every app, doesn't exist anywhere yet. It's time for that to change. To @SahajGarg6, our team, and every person who gave Wispr Flow a chance - this one's for you.
