The story behind Lumen: Lumen began with twin sisters Merav and Michal - two Ironman winners, and PhDs in physiology. As scientists and athletes, they were passionate about developing a way to provide personalized nutrition but knew the only way to measure metabolism was costly and time-consuming.

So they teamed up with entrepreneurs with experience building large companies;  Daniel, Dror, and Avi, and after two years of R&D, they developed the first Lumen prototype. Lumen measured metabolism in a single breath, in less than a minute, instead of an hour-long test in a lab! After four years of hard work and hundreds of beta users, the Lumen team launched on Indiegogo. Lumen broke the $1 million thresholds on IndieGogo in weeks, and now Lumen is leading the way in bringing personalized nutrition to the entire world.
