MiniMed and the five-minute fix
A pump, a sensor, and a small correction every five minutes. MiniMed’s long experiment is about giving people with diabetes less work to do.
Jared Tangney and the Long Road Through the Skin
A graduate-school sensor became a thirteen-year lesson in patience, manufacturing and restraint. The Biolinq co-founder is now trying to make sophisticated biosensing feel almost ordinary.
The Health Company Hiding in Your Kitchen, Your Lab and Under Your Skin
Abbott built a $44.3 billion business by showing up everywhere health becomes measurable - from a breakfast shake to a glucose curve to a repaired heart valve. Its breadth is the strategy, and the complication.
Ultrahuman
Ultrahuman is a Bengaluru-founded health-technology company building a subscription-free wearable and diagnostics ecosystem centered on its Ring AIR and Ring PRO smart rings. Beyond the ring, the company sells a continuous glucose monitor (M1), a home environmental sensor (Ultrahuman Home) and a blood-biomarker service (Blood Vision), stitching them into a single app that turns sleep, movement, metabolic and recovery data into personalized nudges. Founded in 2019 by Mohit Kumar and Vatsal Singhal, it is now the second-largest smart-ring maker by units sold and is expanding US manufacturing to challenge market leader Oura.
Aram Hong
Aram Hong is the CEO and co-founder of Apollon, a Seoul-born, Cambridge-based medtech company building MOGLU, a needle-free continuous glucose monitor powered by Raman spectroscopy. A former EY advisor and Genoplan executive who moved his family from Seoul to Boston to scale the company alongside MIT researchers, Hong has turned a laser-and-optics idea into a CES 2025 Innovation Award honoree that, in peer-reviewed clinical testing, matched the accuracy of leading needle-based sensors from Abbott and Dexcom.
Luna Diabetes
Luna Diabetes (Luna Health Inc.) is a San Diego medical device company building the first automated insulin delivery system designed for the more than 90% of insulin-requiring people who dose with an insulin pen rather than a full-time pump. Its flagship product, Luna, pairs what the company calls the world's smallest insulin patch pump with a fully closed-loop algorithm to automate micro-doses of rapid-acting insulin overnight, when most of the glucose benefit from pump therapy occurs. Founded in 2020 by diabetes-industry veterans John Sjolund, Jon Brilliant and Sean Saint, the company raised a $23.6M Series A in August 2025 and is running a pivotal clinical trial using Time in Range as its primary endpoint.
Michael McShane
Michael (Mike) J. McShane is a biomedical engineer who has spent close to 25 years trying to put readable chemistry under the skin. As James J. Cain Professor II and head of the Department of Biomedical Engineering at Texas A&M University, he builds injectable, biomaterials-based optical biosensors - often called 'smart tattoos' - that glow in response to glucose, oxygen and other body chemistries so doctors can monitor patients continuously and minimally invasively. A Fellow of IEEE, SPIE, BMES and AIMBE, past president of the IEEE Sensors Council and founding chair of the IEEE BioSensors conference, he won the 2012 NIH Director's Transformative Research Award and the 2023 IEEE Sensors Council Technical Achievement Award.
Twin Health
Twin Health builds a Whole Body Digital Twin - a real-time AI model of each member's metabolism that learns from wearable sensors, labs, and daily behavior to reverse type 2 diabetes, obesity, and other chronic metabolic conditions without long-term reliance on medications.
Sharam Fouladgar-Mercer
Sharam Fouladgar-Mercer is the Co-Founder and CEO of Signos, the company behind the first FDA-cleared over-the-counter glucose monitoring system for weight management. A Princeton computer science graduate and Harvard MBA, he played NCAA Division I ice hockey before building a career spanning VC at Sierra and Shasta Ventures, co-founding PR tech company AirPR (later Onclusive), and ultimately creating Signos in 2018 after his own lifelong struggle with weight and the death of his diabetic grandmother inspired him to ask: why wait until someone is sick to give them metabolic data?
Sam Corcos
Sam Corcos is a four-time founder and the co-founder and former CEO of Levels Health, a $300M metabolic health company that pairs continuous glucose monitors with a software layer to help people understand how food affects their blood sugar. He co-founded CarDash (Y Combinator S17, acquired 2020), Sightline Maps, and LearnPhoenix before building Levels into a category-defining health company with $67M raised from a16z and a community of 1,400+ member-investors. In 2025, he joined the Department of Government Efficiency (DOGE) and was appointed U.S. Treasury Chief Information Officer. He is also known for extreme minimalism (one pair of pants, one backpack), tracking time in 15-minute increments, and hosting 100+ intellectual salon dinners in New York and San Francisco.
