Zocdoc CEO Oliver Kharraz explains why Walmart Health and IBM Watson Health failed

In a Fortune commentary, Zocdoc founder and CEO Oliver Kharraz argues that Walmart's shuttered clinic network and IBM's sold-off Watson Health division both collapsed because they treated healthcare as a technology problem rather than a tangle of misaligned incentives and regulations. Walmart closed 51 clinics and its virtual care unit in 2024 after reimbursement and cost pressures made the business unsustainable, while IBM sold most of Watson Health in 2022 after sinking roughly $4 billion into it.

Zocdoc opens its booking infrastructure to insurers and outside health platforms

Zocdoc is expanding its Care Access Network, letting the scheduling technology that runs its own marketplace be embedded into other services such as insurers and search platforms. This means patients could soon book doctor appointments directly through third-party sites rather than only through Zocdoc itself.
