In our new documentary series Backstory, we’re profiling the extraordinary Group Partners at the heart of YC. We’re kicking it off with Surbhi Sarna, YC’s first healthcare and biotech-focused Group Partner. In 2018 Surbhi Sarna sold her company nVision for $275 million to one of the world’s leading healthcare companies. But to understand how Surbhi got where she is today, you have to go back to her sophomore year in high school, when a cancer scare upended her life and set her on an entirely new path.
