About Clair Health
Summary
Clair Health builds the first continuous, noninvasive hormone monitor: a wrist wearable that tracks estrogen, progesterone, LH, and PdG in real time without blood draws. It uses a custom multi-modal biosensor array and an in-house female biology model to capture over 130 biomarkers, replacing periodic lab tests and manual cycle tracking. Women use it to manage fertility planning, athletic performance, skin health, mood, and perimenopause transitions.
Business model
Device purchase plus a pro app subscription, with HSA/FSA eligibility; a founding member tier offers a discounted device and six months of pro subscription free.
Go-to-market
Direct-to-consumer via an early-access founding member program, alongside business-to-business contracts, with the device targeting women across reproductive health, athletic, and menopause use cases.
