Lumen
Lumen is a Continuous Glucose & Metabolic company founded in 2014 and based in Tel Aviv, Israel. It has raised $78.7M in total funding, most recently a Series B in 2022.
Founded in 2014 in Tel Aviv by twin sisters Michal and Merav Mor, both physiology PhDs, Lumen makes a portable breath analyzer that measures the CO2 concentration in a user's exhale to infer whether the body is burning fat or carbohydrates for fuel. The connected app uses that metabolic-flexibility reading to recommend a daily carb intake and personalized nutrition plan. Lumen raised a $62M Series B in 2022 led by Pitango Venture Capital, with Hanwha and Resolute Ventures participating, bringing total funding to roughly $79M. The device was named to TIME's Best Inventions list in 2023.
Lumen pioneered a consumer-priced breath-based proxy for metabolic fuel use, an alternative to glucose sensors for tracking metabolic flexibility.
