Surbhi Sarna is a partner at Y-Combinator and the author of Without A Doubt.

Previously, she was the founder and former CEO of nVision Medical, which sold to Boston Scientific (NYSE: BSX) for $275M. nVision developed a first-in-kind microcatheter for the detection of ovarian cancer. After raising $17M in venture funding, completing three clinical trials, and obtaining two first-in-class FDA approvals, nVision was acquired by Boston Scientific for more than 15X money-in. Surbhi then stayed at Boston Scientific for two years, running the 150+ person commercial organization in preparation for launch.

She is now Y-Combinator’s only and first partner focused exclusively on healthtech, medical devices, and therapeutics and sits on both private and public company boards.

An inspiring take on how to turn others’ doubt —and your own —into rocket fuel to achieve your dreams from entrepreneur, CEO, and healthcare investor Surbhi Sarna.

The very qualities that make you an outlier are, in fact, your strengths. Or so Surbhi Sarna discovered after a teenage cancer scare inspired her to reimagine healthcare, founding a medical start-up to detect early ovarian cancer.

InWITHOUT A DOUBT, she shares her entrepreneurship story of proving the doubters wrong. As a young, brown woman without a medical degree, Ivy-league contacts, or any Silicon Valley street cred—and who had felt different throughout her life—she was often overlooked and underrated.

Undeterred, Sarna used the naysayers as ammunition to help her surpass the expectations of others—and achieve her dreams.WITHOUT A DOUBTis her story of becoming a leader without an MBA, networking without a network, and raising funds when she didn’t know a single venture capitalist, teaching you how to do the same.

Sarna led an all-star team to develop a life-saving medical device, sold her business for $275 million, and became a partner at Y Combinator, one of the most successful venture firms in the world.

Using her own experience, she shows you how to face setbacks, not let impossible standards (including your own) get in the way, lead empathetically, empower others to think differently, and how to convince the right people to help you accomplish your goals.

WITHOUT A DOUBTis “a wise, practical, and compassionate guide to startup success from a determined woman.”— (Kirkus Reviews, *starred review)

Surbhi Sarna lives in the San Francisco Bay area
