About
Medicare Vox (formerly Fair Square Medicare) is a United States-based AI-powered Medicare insurance guidance platform — backed by Y Combinator (W20) — providing Medicare beneficiaries and their families with 24/7 conversational AI-powered assistance for Medicare plan selection, enrollment navigation, and claims guidance through its Vox platform launched in August 2024. Originally founded in 2019 as Fair Square Medicare — a licensed insurance agency helping seniors compare and enroll in Medicare Advantage and Medicare Supplement (Medigap) plans — the company rebranded and launched the Vox AI platform to scale Medicare beneficiary support beyond the capacity of human insurance agents, addressing the complex decision-making that Medicare's 67 million enrollees face when choosing among hundreds of available plans during the annual Open Enrollment Period.
Largest US health insurer with $372B revenue insuring 50M Americans; UnitedHealthcare insurance plus Optum pharmacy and care delivery navigating CEO murder, cyberattack, and claims denial scrutiny.
About
UnitedHealth Group is the largest US health insurance company and one of the largest companies in the world by revenue, operating through two primary business segments: UnitedHealthcare (health insurance for individuals, employers, Medicare Advantage, and Medicaid) and Optum (health services, pharmacy benefits management, and care delivery). Listed on NYSE (NYSE: UNH) and headquartered in Minnetonka, Minnesota, UnitedHealth generates approximately $372 billion in annual revenue and insures approximately 50 million Americans.\n\nUnitedHealthcare provides employer-sponsored group health insurance (the largest business segment), individual marketplace plans, Medicare Advantage plans (one of the largest MA insurers), and Medicaid managed care plans across all 50 states. Optum provides pharmacy benefits management (OptumRx, managing prescription benefits for insured members), care delivery (Optum Health operates clinic networks and physician groups with over 90,000 physicians), and health IT services (OptumInsight provides analytics and technology to health systems and payers).\n\nIn 2025, UnitedHealth Group faces extraordinary challenges following the December 2024 murder of CEO Brian Thompson and the subsequent investigation of its claims denial practices, which drew intense public and regulatory scrutiny of insurance industry practices. The company also manages the aftermath of the February 2024 Change Healthcare cyberattack (Change Healthcare is an Optum subsidiary) — one of the largest healthcare data breaches in US history, affecting approximately 190 million Americans and causing multi-billion dollar financial losses. UnitedHealth competes with Elevance Health (Anthem), CVS Health (Aetna), and Cigna for health insurance and pharmacy benefits market share. The 2025 strategy involves managing regulatory pressure, restoring Change Healthcare operations, and continuing Optum's vertical integration strategy.
