Lumen

Health Tech & Medtech · Tel Aviv-Yafo, Israel · Founded 2014

Lumen.me is a pioneering startup that has developed the world's first portable device for accurate metabolism measurement. This handheld device is designed to track, analyze, and improve metabolic health, a service previously only available to top athletes or through hospitals and clinics. Lumen's device uses a CO2 sensor to determine the concentration of CO2 in a single breath, indicating the type of fuel the body is using to produce energy, which is key to understanding metabolic function. The company operates in the health and wellness market, serving a broad range of clients from fitness enthusiasts to individuals seeking to improve their overall health. Lumen's business model revolves around the sale of its handheld device, but it also provides a comprehensive service that includes personalized meal plans and actionable insights on sleep, workouts, and meal timing based on the metabolic data collected. Lumen's revenue is generated from the sale of the device and potentially from subscription services for ongoing personalized health insights and meal plans. The company's unique selling proposition is its ability to provide users with a daily "Lumen Flex Score" that reflects their metabolic health, based on data from their metabolism, sleep, nutrition, and fitness. This score helps users understand their body's efficiency in using carbs or fats as an energy source and guides them in making lifestyle changes to improve their metabolic flexibility. Keywords: Metabolism, Health and Wellness, Personalized Nutrition, Fitness, Metabolic Flexibility, CO2 Sensor, Portable Device, Lumen Flex Score, Lifestyle Changes, Metabolic Health.
