Gorillas, which competes in Europe, is bringing its 10-minute delivery service to the US.
Sümer believes Gorillas can break the habit of stockpiling groceries by offering US consumers on-demand delivery of "emergency" and "replenishment" groceries.
He named the company Gorillas because his concept is "bold" and "authentic" just like a strong gorilla.
It plans to expand to Italy in May, and also expand its delivery service to more US cities and European countries this summer.
In Europe, Gorillas competes with Berlin-based Flink, Turkish delivery service Getir, and 10-minute delivery service Dija.
