Thync

Thync is a company that develops wearable devices designed to alter a user's mood and mental state through neurosignaling technology. Its first product, released in 2015, was a triangular device worn on the forehead that delivered low-level electrical pulses to the cranial nerves. These "Vibes," as Thync calls them, aimed to either energize or relax the user by stimulating specific neural pathways. The device worked by placing electrodes on the user's forehead and neck, with intensity levels controlled through a smartphone app.

In 2017, Thync launched the Relax Pro, an updated version designed to reduce stress and improve sleep. This model attached to the back of the neck rather than the forehead. Thync's technology does not involve drugs or chemicals, instead using algorithms to generate electric signals that tap into the brain's existing neural circuits.

The company was founded in 2010 by Isy Goldwasser, who previously worked at chemical engineering company Symyx. Thync collaborated with researchers like Dr. Jamie Tyler from Arizona State University to develop its core neurosignaling technology. The company has published studies showing effects like increased facial temperatures in users, which they link to more positive emotional states.
