# Clair Health Raises $11.6M Series A for Hormone-Monitoring Wearable

> Clair Health, founded by two Stanford graduates, has raised an $11.6 million Series A led by Khosla Ventures to build a noninvasive wearable for hormone tracking. The device combines 10 biosensors with AI voice analysis to follow more than 130 proprietary biomarkers, including estrogen, progesterone and other reproductive hormones that today usually require a blood draw to measure. The ambition is to make hormonal health continuously visible the way heart rate and sleep already are. The company says the wearable can read signals like inflammation, energy levels and cycle phase, and it is planning a consumer launch in November with a waitlist already past 25,000 people. The huh factor is the modality: pairing skin sensors with voice as a window into body chemistry is an unusual bet, and hormones have been a stubborn blind spot in the quantified-self boom. If the readings hold up to scrutiny, a category that has been underserved for years suddenly gets a mainstream consumer product, though noninvasive biomarker claims always deserve a healthy dose of clinical caution until validated.
