Coupang is the largest e-commerce company in Korea, delivering millions of items, including fresh groceries, within hours to millions of people, 365 days a year. Our mission is to create a world in which customers wonder, ‘How did I ever live without Coupang?’ Korea is one of the fastest growing e-commerce markets in the world, and Coupang is a leader in this fast-growing industry. Powered by innovative technology and operations, we have set out to transform the customer experience journey–from revolutionizing last-mile delivery to rethinking how customers search and discover on a truly mobile platform. We have invested heavily in infrastructure and technology, building an integrated system that we control from end to end. This enables us to improve as we grow, build new services, and break the tradeoffs between price, selection, and quality that consumers are too often forced to take for granted. 

We have been named as one of the ‘50 Smartest Companies in the World’ by MIT Technology Review, and as one of Forbes magazine’s ‘30 Global Game Changers.’ In 2020, we placed second on CNBC’s ‘Disruptor 50’ list.
