https://techcrunch.com/2021/02/16/krisp-nearly-triples-fundraise-with-9m-expansion-after-blockbuster-2020/ > Krisp, a startup that uses machine learning to remove background noise from audio in real time, has raised $9M as an extension of its $5M A round announced last summer. The extra money followed big traction in 2020 for the Armenian company, which grew its customers and revenue by more than an order of magnitude. > TechCrunch first covered Krisp when it was just emerging from UC Berkeley’s Skydeck accelerator, and founder Davit Baghdasaryan was relatively freshly out of his previous role at Twilio. The company’s pitch when I chatted with them in the shared office back then was simple, and remains the core of what they offer: isolation of the human voice from any background noise (including other voices) so that audio contains only the former.
