Clair Health Raises $11.6 Million Seed Round for Hormone-Tracking Bracelet

Clair Health has raised $11.6 million in seed funding to develop a bracelet that tracks women's hormones, Insider reported. The round was led by Khosla Ventures, with participation from a16z Speedrun, Brydge Club, Treehub, Cartan Capital, AGI House, Insiders VC, and Anne Wojcicki. The company was cofounded by Jenny Duan, 22, who serves as CEO, and Abhinav Agarwal, 24, who serves as CTO.

Both are Stanford graduates who met during a spring break trip organized by the university. Duan previously worked in women's health advocacy and nonprofit efforts, while Agarwal had experience at a glucose-monitoring startup. The bracelet relies on a proprietary math model that maps interactions between the brain and ovaries to regulate hormones.

Funds will support additional research and speed the launch of the device along with a companion app scheduled for November. Clair Health currently employs seven full-time staff and about 14 contract and part-time workers, Agarwal said. Its initial production run of 5,000 devices sold out, and more than 25,000 people remain on a waitlist.

Early orders were priced at $295 with a free app subscription, while the device will retail for $369 with a paid subscription. "Historically, we've seen this category as something that's been deemed niche," Duan said. " Agarwal added.

Insider also published the pitch deck used to secure the funding, with some slides redacted for public release.
