Documented cause
Walmart's internal innovation incubator Store No. 8 launched Jetblack, a text-based personal shopping concierge service for affluent New York parents, in 2018. The service charged $600/year but required massive human labor to fulfill requests. By early 2020, Walmart shut down Jetblack after spending an estimated $40M-$60M and serving fewer than 1,000 subscribers. The unit economics were catastrophically negative and unscalable.
Lesson
“Luxury concierge models funded by mass-market retailers have irreconcilable unit economics.”
