The company launched on the New York State health plan marketplace and recently added New Jersey. Oscar is setting itself apart from other health insurers by emphasizing technology, data and easy-to-understand explanations of its services.
Co-founder Josh Kushner has said he was inspired to start the firm when he couldn't make sense of a bill from his health insurance company. The Oscar home page features simple language, and there are good search functions to find a specialist. So far, it claims that 40,000 customers have enrolled—more than double what it had a year ago.
