About Us

TUO is a Chicago-based start-up from a group of 3 co-founders coming from a variety of professional backgrounds (tech industry, lighting design, and operations), but with shared struggles with circadian health and wellness.  We were disappointed in the circadian products on the market, and working with Prof. Jay Neitz Ph.D and James Kuchenbecker Ph.D at the University of Washington Department of Ophthalmology developed and proved this totally new approach to light and circadian health.
