Lumen

Israel-based Lumen is a passive remote patient monitoring platform that offers a vape-like handheld device with sensors to measure an individual’s carbon dioxide levels in their breath. This is done to determine whether the body is burning carbs or fat for energy. The gathered data is connected to a mobile app to provide users with personalized recommendations on food, exercise, and sleep, thereby preventing diseases and improving their metabolic health. These personalized recommendations are determined using machine learning based on the user’s lifestyle and metabolic profile, which otherwise is traditionally only available in hospitals and clinics.

Furthermore, the company claims to have collected approximately two million measurements per month using the hardware device. Lumen also integrates with other health data platforms such as Apple Healthkit, Google Fit, and Garmin. The device is sold for USD 299 with USD 19 per month for the platform.

Key customers and partnerships

The company is engaged in carrying out research studies in metabolic health and has partnered with academic institutions, including Purdue University’s Whistler Center for Carbohydrate Research, the University of Toronto’s Faculty of Kinesiology and Physical Education, and ARU Cambridge.

Funding and financials

In December 2022, the firm raised USD 62 million in a Series B funding round led by Pitango Venture Capital, which was allocated toward expanding its presence geographically, and supporting research partnerships with academic institutions.
