Lume Health debuted its continuous hormone-monitoring band at TechCrunch Disrupt 2026.
Founded by former Apple sensor engineer Vicki Powell and physician Dr. Jonathan Moustakis, the health tech company is preparing its wearable for commercialization. An alternative to traditional blood- and saliva-based hormone testing, the device uses sweat-sensing technology to track hormone levels, starting with cortisol, through the skin on the inside of the wrist.
“What we’re building is essentially a miniature lab on your wrist,” said Powell, also the company’s CEO. “Hormones are constantly changing. So much of the value comes from measuring how your hormones change over time, which meant making something easy to wear was important to us from the start.”
Moustakis added: “Seeing the pattern over time, rather than a single measurement, could be so valuable. That continuous view has the potential to give us an entirely new way of understanding what is happening in the body over time.”
According to the company, research showing similarities between sweat and blood markers informed the development of the first device and its proprietary sweat-sensing technology. With a 25,000-person waitlist, Lume is currently in beta development and plans launch in 2027, alongside additional hormone- and biomarker-tracking features.
