NextSense

NextSense develops wireless earbuds that monitor brain activity and enhance sleep quality. The earbuds use sensors to capture brain rhythms and track body movement, measuring sleep metrics and providing an intelligent relaxation experience with science-backed audio. The product automatically pauses audio when sensors detect that the user has fallen asleep. Founded in 2020 and headquartered in Mountain View, United States, NextSense has raised approximately $35.3M in Series A funding from investors including Angelini Ventures, Ascension Ventures, Satori Capital, Corundum Neuroscience, and Particular Ventures. The company employs 23 people and combines consumer earbud form factor with electroencephalography (EEG) sensing technology, enabling continuous brain activity monitoring outside clinical settings for sleep optimization, cognitive performance tracking, and potential early detection of neurological conditions.
