Paradigm co-founder Fred Ehrsam co-founded a new company, Nudge, which is developing ultrasonic headphones

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 necessary factors to become a mainstream consumer product in the near future. The research progress of ultrasound has accelerated in the past few years and has begun to produce promising results. Nudge is currently a team of 11 engineers and scientists, and team members have worked in companies and projects such as Vision Pro, Neuralink, SpaceX and top university laboratories such as Stanford."
