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

Coinbase and Paradigm co-founder Fred Ehrsam posted on X, "I have co-founded a new company called Nudge with Quintin Frerichs. Nudge is developing an ultrasonic earphone that aims to enhance human experience by changing brain states. With just the press of a button on this earphone, users can fall asleep, improve focus, quit bad habits, or improve mood. We believe this technology has the potential to improve daily life more than any other technology. Ultrasonic neural modulation is a necessary factor in becoming a mainstream consumer product in the near future. Ultrasonic research has accelerated in recent years and has begun to produce promising results. Nudge is currently a team of 11 engineers and scientists who have worked at top universities, laboratories, and companies such as Vision Pro, Neuralink, SpaceX, and Stanford."
