SONA, formerly MindSpire, is developing a consumer neurotechnology wearable for stress regulation, recovery, sleep, and cognitive performance. The company sits within consumer neuromodulation, using non-invasive vagus nerve stimulation.

Its system uses transcutaneous auricular vagus nerve stimulation through the ear, combined with biometric sensing, breathing, sound, and app-guided sessions. Public materials describe an adaptive platform that reads signals such as HRV and respiration rate, then adjusts stimulation protocols in response to user physiology and goals.

SONA targets consumers seeking nervous-system regulation and performance-oriented wellness support rather than a diagnosed clinical population. The company raised pre-seed funding in 2025 to launch its SONA wearable, placing it in an early commercial wellness category.
