SunFly is developing invisible ink stamps to be worn underneath sunscreen that help users know 1) if they have applied enough sunscreen, 2) when to reapply and 3) when they have reached their maximum UV for the day.SunFly's technologies will not only help protect consumers from the harmful effects of UV radiation, but may also help sunscreen manufacturers sell 2-3x more sunscreen. We anticipate a strong IP portfolio and an early exit.
