Back Market has created a marketplace to connect companies that restore used gadgets with consumers through a one-stop shopping experience, complete with warranties and customer service. While the company has seen meteoric growth, particularly since its expansion in the U.S., overall sales of used gadgets remain small compared to those of brand-new devices.
