🏥 '''Oscar Health''' is a U.S.-based [[Definition:Health insurance | health insurance]] company founded in 2012 that became one of the most prominent examples of an [[Definition:Insurtech | insurtech]] venture attempting to fundamentally reimagine how consumers interact with their health coverage. Co-founded by Mario Schlosser, Joshua Kushner, and Kevin Nazemi, Oscar launched in the wake of the Affordable Care Act's creation of public health insurance exchanges, positioning itself as a technology-first insurer designed around user experience, transparency, and data-driven care navigation. Unlike legacy health insurers that evolved from paper-based administrative systems, Oscar built its technology stack from the ground up, incorporating features such as telemedicine integration, personalized care teams, and a mobile-first interface that set it apart in a market long criticized for complexity and opacity.

⚙️ Oscar operates as a full-stack [[Definition:Insurance carrier | insurance carrier]], meaning it underwrites and administers its own [[Definition:Health insurance policy | health insurance policies]] rather than simply acting as a technology layer on top of another insurer's infrastructure — though it has also pursued partnerships and platform arrangements with other carriers and health systems. The company primarily sells individual and small-group plans through the [[Definition:Health insurance exchange | ACA marketplace exchanges]], and it has expanded into [[Definition:Medicare Advantage | Medicare Advantage]] offerings. Oscar's technology platform, +Oscar, has been offered to other insurers and provider organizations as a way to monetize the company's digital infrastructure beyond its own [[Definition:Policyholder | policyholder]] base. A notable element of its model is the emphasis on [[Definition:Preventive care | preventive care]] incentives and simplified [[Definition:Claims processing | claims processing]], aiming to reduce friction for members while steering utilization toward cost-effective care pathways.

💡 Oscar Health's significance to the insurance industry extends well beyond its own [[Definition:Market share | market share]]. Its high-profile entry into health insurance — culminating in a public listing in 2021 — helped catalyze broader industry attention to consumer-centric design and digital-native distribution in a sector that had been slower to adopt [[Definition:Digital transformation | digital transformation]] than property and casualty lines. The company also demonstrated both the promise and the difficulty of building an insurance carrier from scratch: Oscar faced persistent [[Definition:Underwriting loss | underwriting losses]] in its early years as it navigated the volatility of ACA risk pools and the capital intensity of scaling a health plan. Its journey has become a closely studied case in [[Definition:Insurtech | insurtech]] circles for what it reveals about the tension between rapid technology-driven growth and the actuarial discipline required to sustain an [[Definition:Insurance company | insurance company]] over time.
