About us

Hi there, we’re Sofia and Justin! We became friends years ago as Emergent Ventures grant fellows, each pursuing big ideas in biology and biometrics. Despite our different backgrounds, we share one thing in common — a deep frustration with U.S. healthcare. This is why we’re harnessing the latest advances in AI and biology, along with regulatory changes, to build a sustainable, patient-first healthcare system.

Justin Zheng, CEO, is a Bay Area native with a proven track record in consumer-focused ventures. He has been building startups since high school and raised millions of dollars for his previous companies, one of which was successfully acquired. With AI expertise that predates its current “buzzword” status, Justin provides strong technical leadership.

Sofia Sigal-Passeck, COO, is also a serial founder and a graduate of Yale-NUS College. She previously served as CEO of Uniphage and brings extensive experience in biology and healthcare. At just 22, Sofia already had her own biology lab and served as a Principal Investigator on a U.S. National Science Foundation grant, where she used AI to “understand” viral genomes.

Unlike many companies, we designed our platform primarily for everyday people, not institutions. That means you get a direct-to-consumer experience built with you in mind. We believe in being open and honest, and our top priority is always putting our users first.
