Coupang Inc.

Coupang operates as an e‑commerce platform headquartered in South Korea, providing an online marketplace where consumers can purchase a wide variety of goods ranging from electronics to household items. The company integrates its own logistics and delivery network to fulfill orders, aiming to offer fast shipping within the domestic market. Its service model includes features such as same‑day or next‑day delivery for many products, supported by a fleet of warehouses and distribution centers located across South Korea. Coupang’s primary customer base consists of South Korean shoppers who access the platform via web and mobile applications. The firm also engages in partnerships with third‑party sellers who list their products on the marketplace, expanding the range of available items.

Coupang has been repeatedly highlighted in public reports for significant data‑breach incidents involving insider access to customer information. In 2025, a former employee accessed personal data of tens of millions of customers, leading to regulatory fines, compensation vouchers, and class‑action lawsuits in the United States. Another incident in mid‑2025 exposed names, phone numbers, delivery addresses, email addresses, and order histories for up to 33.7 million accounts, with the company attributing the breach to an insider using overseas servers. A separate breach in early 2025 involved a former engineer exploiting a stolen signing key to bypass authentication and view names and phone numbers of roughly 33.7 million users, a delay in reporting that authorities cited as a management failure. These events have subjected Coupang to heightened scrutiny from South Korean regulators, resulted in substantial financial penalties, and prompted the firm to offer large‑scale compensation vouchers to affected users while also facing litigation abroad concerning disclosure practices.
