Oscar Health was co-founded in 2012 by Joshua Kushner, Kevin Nazemi, and Mario Schlosser, who envisioned a technology-driven health insurance company focused on simplifying the consumer experience. Over the years, the company has attracted substantial financial backing from prominent venture capital firms, institutional investors, and strategic partners—such as Founders Fund, Thrive Capital, and Alphabet's capital investment arms—which provided the initial capital and tech infrastructure necessary to scale its digital insurance platform across multiple state markets.
