Odaily News Fred Ehrsam, co-founder of Coinbase and Paradigm, said in an X post: "I have co-founded a new company called Nudge with Quintin Frerichs. Nudge is developing an ultrasonic headset that aims to enhance the human experience by changing the state of the brain. Just press the button of the headset to help users fall asleep, improve concentration, quit bad habits or improve mood. I believe this technology has the potential to improve people's daily lives more than any other technology. Ultrasonic neuromodulation has the factors necessary to become a mainstream consumer product in the near future. Advances in ultrasound research have accelerated in the past few years and have begun to produce promising results. Nudge is currently a team of 11 engineers and scientists. Team members have worked in companies and projects such as Vision Pro, Neuralink, SpaceX, and top university laboratories such as Stanford."
