Meet the author
Surbhi Sarna is an accomplished entrepreneur, investor, and author. As the founder and former CEO of nVision Medical, she developed a ground-breaking microcatheter for early ovarian cancer detection. After raising $17 million in venture funding and obtaining FDA approvals, Sarna sold nVision to Boston Scientific for $275 million. Her entrepreneurial journey was inspired by a teenage cancer scare, fuelling her passion for healthcare innovation. Currently a partner at Y Combinator, Sarna focuses exclusively on healthtech, medical devices, and therapeutics investments. She serves on both private and public company boards, including Penumbra Medical and Biora. Sarna’s debut book, “Without a Doubt,” shares her experiences as a young, brown woman navigating the challenges of entrepreneurship and leadership without traditional credentials. She has been featured on Forbes’ 30 under 30 list and Inc.’s Female Founder 100 list. Sarna lives in the San Francisco Bay area with her husband and two children, where she also pursues grape growing.

— Arianna Huffington, Founder & CEO, Thrive Global
“Perhaps as a result of the ways in which she was underestimated, Sarna’s approach to entrepreneurship, which she articulates through warm and humorous advice embedded in her life story, is profoundly empathetic, both for her co-workers and community and for herself.[Without a Doubt is] a wise, practical, and compassionate guide to startup success from a determined woman.”
