Clair’s non-invasive wearable constantly tracks key hormones in actual time, signaling a broader shift towards women-first well being tech in health and wellness
There appears to be a brand new wearable assembly practically each want throughout health and wellness, however startup Clair is hoping to disrupt an area that’s solely simply now catching as much as ladies’s distinctive physiology.
The brand new wellness tech model, based by Stanford graduates Jenny Duan and Abhinav Agarwal, has pioneered a non-invasive steady hormone monitor, which the corporate claims is the primary of its variety.
The Clair wearable is a response to ladies traditionally being dismissed, misdiagnosed or ignored in medical settings, particularly for circumstances associated to their hormone well being, offering a extra proactive fairly than reactive method to healthcare with hormone insights arriving earlier than the signs do.
“Girls have been making well being selections with virtually no hormonal knowledge. Think about managing diabetes with out ever checking glucose; that’s primarily what ladies have been requested to do with their reproductive and metabolic well being,” mentioned CEO and co-founder Duan. “Clair’s mission is to alter that by giving ladies the hormonal knowledge they’ve by no means had entry to, constantly and non-invasively, permitting them to make knowledgeable selections about their fertility, cycle, and transition by way of perimenopause.”
“We’re constructing towards a future the place that modifications. The place noninvasive sensing turns into the inspiration of healthcare,” the web site reads. “The place your physique’s indicators are heard clearly, constantly, and acted on earlier than small points develop into crises. Intelligence that learns, predicts, and helps you keep forward.”
Clair depends on multimodal sensing, with proprietary tech of 10 biosensors and 500 biomarkers to supply customers with actionable insights to optimize fertility monitoring and athletic efficiency, handle hormonal well being and navigate life levels like perimenopause.
The wrist wearable supplies real-time monitoring of estrogen, progesterone, LH and FSH with out blood or urine checks.
“At the moment’s wearables observe steps, coronary heart charge, and sleep, however they inform ladies nothing in regards to the hormones that basically form how they really feel, carry out and age,” CTO and co-founder Agarwal mentioned. “Clair Well being’s mission is to construct the primary gadget to constantly monitor hormones like estrogen, progesterone, LH, and FSH and not using a blood draw. That’s the hole: not one other health tracker, however an precise window into your hormonal well being.”
The tech additionally leverages synthetic intelligence (AI) — particularly, AI educated on various feminine physiology, making an allowance for elements like PCOS and anovulation, to precisely present monitoring and intel for the practically one-third of girls with irregular cycles.
It additionally attracts upon different well being metrics and places them within the context of hormonal shifts, together with:
- Pores and skin temperature, which may mirror hormonal modifications like rises in progesterone post-ovulation
- Resting coronary heart charge to trace cardiovascular patterns that fluctuate all through the menstrual cycle in response to estrogen and progesterone
- Coronary heart charge variability (HRV), which measures autonomic nervous system modifications influenced by hormonal fluctuations
- Sleep monitoring to see how relaxation is affected by progesterone and estrogen ranges
- Breath charge and respiratory modifications linked to progesterone’s impact on thermoregulation
- Electrodermal exercise and movement monitoring, which captures stress responses and exercise patterns that work together with hormonal states
One of many most important goals of the gadget is to allow ladies to know their our bodies higher and dwell extra knowledgeable life round their cycles, because the model claims it has a 94% cycle part classification accuracy.
The continual insights from Clair might assist ladies perceive the patterns behind their temper and vitality ranges, placing into context why some days ladies expertise increased or decrease ranges of vitality versus exhaustion, which matches hand in hand with why some exercise days are simpler than others.
The model is positioning itself as a possible severe competitor to different main wearables akin to Oura or Apple Watch. For example, Clair is hoping that ladies will select its wearable for the knowledgeable method it takes, explaining how steep rises in progesterone in a single day may nonetheless trigger exhaustion after eight hours of sleep.
Whereas the wearable is geared in the direction of hormone well being, the model can be hoping to disrupt the health house by encouraging customers to align coaching, restoration and each day exercises with their cycle to optimize efficiency, handle vitality and cut back harm threat by enabling coaching changes with cycle-based physiological capability fairly than pushing by way of or holding again throughout completely different phases.
The Clair app launches this month for beta testing, because the wearable gadget is on observe to launch later this yr in November.
Different manufacturers are beginning to reply to the elevated demand for hormone monitoring, particularly as ladies in midlife develop into a key demographic for wellness corporations.
Clair follows the launch of Peri, an AI-powered wearable designed to detect and decode signs of perimenopause from ladies’s well being firm IdentifyHer.
Final yr, startup Eli Well being additionally raised $12 million in Collection A funding to help its non-invasive and instant hormone monitoring system, based mostly on at-home saliva checks.
In the meantime, Allbirds co-founders Liz and Joey Zwillinger raised $7 million in seed funding on the finish of 2025 for Biologica, a new women’s health brand with supplements engineered for women’s hormonal age, not organic age, to help reproductive years, perimenopause and postmenopause.
