Bía Neuroscience is developing a consumer sleep neurotechnology product built around a smart sleep mask. The company positions Bía as a sleep system that measures brain activity and supports sleep improvement rather than as a clinical diagnostic or therapeutic device.

The mask uses functional near-infrared spectroscopy to measure brain activity during sleep. It combines brain sensing with neurofeedback, neural soundscapes, movement and temperature sensing, and app-based sleep insights to personalize the user experience.

Bía is aimed at consumers seeking better sleep quality, with use cases including sleep tracking, sleep-stage guidance, and recovery-oriented wellness. The company is best understood as a consumer neurotech startup applying brain-sensing and feedback concepts to the sleep-wearables category.
