K Health's virtual primary care platform is enhanced by an AI copilot to complete the initial patient intake, summarizing relevant history from the EMR, and generating “the perfect note” to reduce the time providers spend on basic data collection and non‑clinical tasks.

Unlike other virtual medicine companies, K Health delivers comprehensive, longitudinal primary care in a virtual setting, enabling our clinicians to be true primary care providers without sacrificing scope of practice or continuity of care.

As a venture‑backed startup trusted with nearly $400 million in funding and a $900 million valuation as of July 2024, K Health is well‑positioned for sustained future growth. We are expanding our partnerships with major health systems (Cedars‑Sinai, Hackensack Meridian Health, Hartford Health Care), enhancing accessibility and quality of care by pairing people with technology. Our providers are credentialed at these renowned academic health systems and adhere to their clinical guidelines, ensuring patient‑first, evidence‑based care.

Fully integrated into Epic, our AI platform enables K Health to operate as an extension of existing healthcare systems, benefiting from a built‑in network of specialists and social services to seamlessly serve patients within those communities. Our unique care delivery model enables our providers to deliver the same high‑quality, accessible care to a mixed‑payer population, including those with commercial insurance, Medicare, and Medicaid.
