📝 Lumen raises $77M

News of the Day

Twin sisters Michal and Merav Mor, PhDs in physiology and former Ironman triathletes, turned a personal quest for peak performance into Lumen, a health tech startup that’s now raised $77 million to transform how we understand metabolism. Their hand-held breath analyzer, first tested on family over Friday dinners, now powers over 75 million metabolic data points from 350,000 users, offering real-time insights into diet, exercise, sleep, and stress. Rejected from med school and now featured on CNBC's 2025 Changemakers list, the sisters credit athletic grit, scientific obsession, and maternal wisdom for their success, proving that persistence, psychological safety, and no post-dinner meetings can scale a company just as powerfully as code and capital.
