Surbhi Sarna, 28
Founder, nVision Medical
At age 13, Sarna suffered from ovarian cysts so painful they made her faint. Doctors couldn’t tell her if they were cancerous. She vowed to create a technology to detect ovarian cancer quickly and early. The company she now runs aims to do just that, and has raised $4.5 million from Catalyst Health Ventures, Draper Associates, and Astia, a group that assists female entrepreneurs.
