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.
