On August 7, Fred Ehrsam, co-founder of Coinbase and Paradigm, said in a social media post that "a new company called Nudge has been co-founded with Quintin Frerichs. Nudge is developing a revolutionary ultrasonic headset designed to enhance the human experience by altering the state of the brain. Simply pressing a button on the headset can help users fall asleep, improve concentration, kick bad habits or improve their mood. We believe this technology has the potential to improve people's daily lives more than any other technology. Nudge is currently a team of 11 engineers and scientists who have worked in places and projects such as Vision Pro, Neuralink, SpaceX and top university labs such as Stanford. "
