NextSense

NextSense is a brain health technology company developing EEG-powered smartbuds that actively improve sleep, focus, and relaxation through adaptive, brain-responsive audio. Incubated at Google X and founded by Jonathan Berent, the company's Smartbuds are the world's first truly wireless consumer earbuds with embedded EEG sensors that detect sleep stages in real time and deliver targeted audio interventions. NextSense raised a $16 million Series A led by Ascension Ventures to launch the Smartbuds and expand into medical applications. The platform uses machine learning to classify sleep stages with clinical-grade EEG accuracy.
