Stanford graduates Jenny Duan and Abhinav Agarwal wish to resolve two arduous issues: create a handsome wearable and measure hormones to assist ladies perceive their well being higher.
The pair is constructing a startup referred to as Clair Well being to trace irritation and bloating markers, power ranges, and cycle section classification to offer insights into cycle irregularities and perimenopause in addition to hormonal fluctuations and how one can navigate these modifications.
The corporate has raised $11.6 million in a funding spherical led by Khosla Ventures, with participation from startup accelerator program a16z speedrun, Brydge Membership, Treehub, Cartan Capital, AGI Home, Insiders VC, Anne Wojcicki, and Stephanie Coleman.
The startup mentioned that, with the intention to gather extra information particular to every consumer, it makes use of voice-based onboarding to grasp their well being markers. What’s extra, the corporate claims it has skilled its personal AI to research voice-based biomarkers and decide which section of their cycle a consumer is in after only a few minutes of dialog.
“What we discovered is that in ladies’s well being and within the present state of apps, ladies can’t talk a considerable amount of signs as a result of the apps are constructed for less than particular ones. With our voice stack, we’re giving our customers a technique to talk their very own issues in their very own manner,” Duan mentioned.

By means of its wearable, Clair Well being mentioned it’s capable of decide what’s inflicting hormones to vary and the way the physique responds to these modifications by evaluating the biomarkers picked up by its sensors. It additionally repeatedly screens modifications via the 4 phases of a menstruation cycle and doesn’t simply depend on the day of menstruation. By means of these markers, the app reveals details about the tempo of ageing, irritation and bloating, and the speed of perceived exertion.
Clair Well being additionally needs to assist ladies in search of look after menopause and perimenopause by offering extra information to share with healthcare suppliers, permitting them to obtain higher help quite than orally recounting their signs.
Duan mentioned that grew to become interested by ladies’s well being whereas working at a nonprofit in Portland, Oregon, throughout faculty. Later, she took a category at Stanford centered ladies’s well being and nonprofits, and through that point, she met Agarwal.
The startup argues that typical well being monitoring gadgets like Apple Watch or a Pixel Watch depend on sensors like a gyroscope, an optical/PPG sensor, and a temperature sensor, which aren’t sufficient to trace hormonal well being. Clair Well being’s machine has 10 biosensors, together with a novel biomagnetic sensor for hormonal insights.
“Till at present, there hasn’t been a single machine, be it invasive or noninvasive, that may seize insights into hormones in actual time and get to the supply of an issue. We didn’t begin by considering of constructing a selected piece of {hardware}. We simply wished to trace hormones repeatedly,” Duan instructed TechCrunch.
The corporate mentioned that it’s constructing its personal mannequin primarily based on totally different biomarkers for ladies’s well being, with information partnerships with entry to a number of million digital well being information and longitudinal well being information. By means of its information partnerships, it needs to create insights into totally different points, together with endometriosis, PMDD (Premenstrual Dysphoric Dysfunction), perimenopause, and extra.
The startup is at the moment testing its machine with a closed group of beta customers and plans to ship items in November at a value level of $369 paired with a $9.99 month-to-month subscription. Customers can place pre-orders for the machine now.
Mary Minno, an investor at Treehub, a Stanford-adjacent residency backed by the AI Well being Fund, mentioned that Clair Well being is fixing the issue of giving ladies actionable perception into their hormonal well being.
“Customers desire a product that does what it says it will do. Hormonal well being measurement at present continues to be archaic — my perimenopausal associates are nonetheless getting blood attracts to grasp the efficacy of hormone therapies. Out of the gate, Clair goals to ship a product that shines a lightweight on what beforehand required a blood draw,” Minno instructed TechCrunch by way of electronic mail.
Startups are attempting many approaches to measure hormone well being. For example, Degree Zero Well being focuses on steady monitoring through glucose monitor-style devices, whereas Hormona relies on home tests. Then there are apps like Ourself Health that depend on AI to offer insights primarily based on guide logging finished by customers.
