Coupang

Sells goods online with its own overnight delivery

Coupang runs one of South Korea's largest online stores, selling groceries, electronics, household goods and fashion to consumers and small businesses. Rather than relying on outside carriers, it delivers most orders through its own warehouses and drivers, and its Rocket Delivery service brings millions of items to doorsteps overnight or the same day. Shoppers order through the Coupang app or website, and the company earns money from its own retail sales, commissions and fulfillment fees from outside sellers, and a paid membership. Coupang was founded in Seoul in 2010 and is headquartered in Seattle, with most of its operations and staff in South Korea.
