Last updated August 31, 2026
Overview
Oscar Health, legally Oscar Management Corporation, is a United States health insurance company that combines insurance underwriting with consumer-facing technology and healthcare services. It was founded in 2012 by Mario Schlosser, Joshua Kushner, and Kevin Nazemi, who had been classmates at Harvard Business School. The company entered the market as the Affordable Care Act was creating new individual insurance exchanges and expanding access to regulated coverage. Oscar’s original proposition was to make health insurance easier to purchase and use through a more comprehensible digital interface, member support services, telemedicine, and clearer presentation of claims and healthcare pricing. The company initially concentrated on individual and family plans sold through the Affordable Care Act marketplace and directly to consumers. It enrolled approximately 16,000 members in its first year and expanded into New Jersey in 2015. By 2016, it served members in New York, New Jersey, California, and Texas. Rapid growth exposed the difficulty of accurately pricing a relatively new insurance pool: early losses were associated with members having higher medical needs than Oscar’s models had anticipated. In response, Oscar reduced or exited certain markets, adjusted its provider networks, and placed greater emphasis on controlling medical costs and managing the member experience. Oscar also developed physical and service-oriented extensions of its insurance model. In 2016 it opened the Oscar Center in Brooklyn Heights in partnership with Mount Sinai Health System, offering primary care and behavioral-health services to Oscar policyholders together with educational programming. The company later expanded beyond individual coverage. In 2017 it entered the small-group market in New York and announced arrangements involving Cleveland Clinic, Humana, and other partners. In 2020 it partnered with Cigna on Cigna + Oscar, a small-business health insurance offering intended for selected markets. Oscar has also sold Medicare Advantage plans in markets including New York City and Houston. Its operating model relies on digital enrollment and member tools, telemedicine, healthcare-focused software interfaces, provider and claims information, and a service approach known as Concierge. The company established a member-services operation in Tempe, Arizona, and maintains a technology presence in Los Angeles in addition to its New York headquarters. Its consumer marketing has generally emphasized simplicity, education, approachable design, and the reduction of friction in dealing with insurance. Oscar financed its expansion through multiple private funding rounds involving investors such as Founders Fund, Thrive Capital, General Catalyst, Khosla Ventures, CapitalG, Fidelity Investments, and other institutional backers. It became a public company in 2021 through an initial public offering on the New York Stock Exchange under the symbol OSCR. The business continued to adjust its geographic footprint; for plan year 2023 it announced exits from Arkansas and Colorado. In April 2023, co-founder Mario Schlosser moved from chief executive officer to president of technology, while Mark Bertolini became CEO. Oscar remains an active health insurance brand focused primarily on United States commercial and government-sponsored health coverage, supported by technology and healthcare-service capabilities.
History
Oscar Health was established in 2012 by Mario Schlosser, Joshua Kushner, and Kevin Nazemi. The founders sought to apply software-oriented design and consumer service practices to American health insurance. Oscar began selling coverage during the period when the Affordable Care Act exchanges were being implemented, giving it an opportunity to serve consumers shopping for individual and family plans in a newly structured marketplace. Its first year produced approximately 16,000 members, and the company expanded into New Jersey in 2015. The early expansion period was accompanied by significant operational and actuarial challenges. By 2016 Oscar had about 145,000 members across New York, New Jersey, California, and Texas according to reported company figures. The insurer found that medical utilization among some early enrollees was higher than anticipated, contributing to substantial losses. Oscar responded by withdrawing from the New Jersey marketplace, reshaping its New York provider network, and focusing more closely on pricing, care management, and the member experience. It also opened a Concierge operation in Tempe, Arizona, to support members. Oscar pursued an integrated model rather than limiting itself to online policy sales. In 2016 it opened the Oscar Center in Brooklyn Heights through a partnership with Mount Sinai Health System. The center provided primary care and behavioral-health services to eligible policyholders and hosted member education activities. It closed in 2020 during the COVID-19 period. In 2017 Oscar entered the small-group segment in New York, announced a Cleveland Clinic relationship for plans in northeastern Ohio, and described further expansion across several states. It also worked with Humana on small-business coverage in the Nashville area. The company continued to broaden its commercial model through partnerships. In 2020 Oscar and Cigna announced Cigna + Oscar, a small-business insurance offering intended to launch in selected markets and expand over time. Oscar also offered Medicare Advantage plans in New York City and Houston, alongside its individual and family marketplace business. Its technology proposition included telemedicine, digital enrollment, member applications and interfaces, and systems designed to make claims and pricing information easier to understand. Oscar’s growth was funded by private investors including Founders Fund, Thrive Capital, General Catalyst, Khosla Ventures, CapitalG, Fidelity Investments, and others. The company raised a reported $1.2 billion in connection with its 2021 initial public offering and began trading on the New York Stock Exchange as OSCR. Subsequent strategy involved continuing geographic optimization, including planned exits from Arkansas and Colorado for the 2023 plan year. In April 2023, co-founder Mario Schlosser moved from CEO to president of technology, and Mark Bertolini assumed the CEO role. Oscar remains an active United States health insurer whose brand is built around digital access, consumer-oriented service, and technology-supported insurance administration.
