Gr4vy Lands Wizlo Deal to Shore Up Virtual Care Payments

Wizlo tapped Gr4vy's payment platform to end processor lock-in and keep recurring billing steady for virtual care patients.

America's boom in subscription telehealth, particularly in weight-loss and longevity treatment, rests on an unglamorous assumption: that a monthly card charge will simply go through. Wizlo, which supplies the back-end software for such clinics, has just admitted how shaky that assumption is. On July 28th it adopted Gr4vy, a payment orchestration platform, to stop its billing from depending on any single processor.

The problem it is solving is oddly circular. Telehealth grew rapidly after the pandemic, prompting regulators to tighten rules on remote prescribing and banks to tighten their tolerance for telehealth clients, whose products sit in a compliance grey zone somewhere between medicine and mail-order retail. The same policies meant to make virtual care safer have made the plumbing behind it more brittle. A processor can change its terms, or a sponsor bank can reassess its appetite for health-related merchants, and a patient mid-treatment finds their subscription quietly lapses.

Wizlo's previous fix was no fix at all: each new processor required bespoke engineering, and switching meant re-collecting card details from every customer, since payment tokens were tied to the processor that issued them. Gr4vy's contribution is to hold those tokens itself, one layer removed from any single bank or processor, so Wizlo can add Stripe, Adyen or Authorize.net without asking patients to re-enter their cards.

John Lunn, Gr4vy's chief executive, put the logic plainly: "Telehealth companies can't afford to be limited by processor lock-in." Kevin Singh, Wizlo's co-founder, framed it as insurance against a regulatory climate that "arrives with little warning."

The arrangement does not eliminate dependency so much as relocate it, from banks to a single orchestration layer now sitting between Wizlo and its money. That may be a sound trade, given how quickly card-network and sponsor-bank rules for telehealth have shifted since 2023. But it is a reminder that in a sector selling continuity of care, the biggest threat to that continuity is rarely medical. It is administrative.
