Mario Schlosser.

Mario Schlosser is the Co-Founder and former CEO of Oscar Health, the technology-driven health insurance company founded in 2012 to offer a more transparent, user-friendly health insurance experience.

Schlosser, originally from Germany, co-founded Oscar with Joshua Kushner and Kevin Nazemi after experiencing firsthand the confusion and frustration of navigating American health insurance. Oscar was one of the first health insurance companies built around a modern technology stack-offering a mobile app, transparent pricing, concierge services, and telehealth integration. The company went public in 2021 and has grown to serve over 1 million members across multiple states through individual, Medicare Advantage, and small business plans. While Oscar has faced profitability challenges common in health insurance, Schlosser's vision of making health insurance more consumer-friendly through technology has influenced the entire industry. After stepping down as CEO, he now serves as Chief Technology Officer, focusing on applying AI to transform healthcare delivery and insurance operations. His work bridging consumer technology and regulated health insurance represents one of the most ambitious transformations in American healthcare.
