This “smoking gun” killed the McDonald’s ice cream hackers’ startup

A little over three years have passed since McDonald’s sent out an email to thousands of its restaurant owners around the world that abruptly cut short the future of a three-person startup called Kytch—and with it, perhaps one of McDonald’s best chances for fixing its famously out-of-order ice cream machines.

Until then, Kytch had been selling McDonald’s restaurant owners a popular Internet-connected gadget designed to attach to their notoriously fragile and often broken soft-serve McFlurry dispensers, manufactured by McDonald’s equipment partner Taylor. The Kytch device would essentially hack into the ice cream machine’s internals, monitor its operations, and send diagnostic data over the Internet to an owner or manager to help keep it running. But despite Kytch’s efforts to solve the Golden Arches’ intractable ice cream problems, a McDonald’s email in November 2020 warned its franchisees not to use Kytch, stating that it represented a safety hazard for staff. Kytch says its sales dried up practically overnight.
