# The 42 largest e-commerce companies in South Korea

Tamtam tracks 42 e-commerce companies headquartered in South Korea. This list ranks all of them by number of employees on LinkedIn, led by Samsung Mobile, NAVER Corp and (주)우아한형제들 (Woowa Bros.). Their median headcount is 525. Half of them were founded in 2000 or later. The most common headquarters are Seoul (24) and Seongnam (3).

The e-commerce companies in South Korea listed here are primarily large firms, many of which have diversified interests beyond their initial offerings. The list includes technology and internet giants like NAVER Corp, which offers a search portal and messenger services, and NHN, providing gaming, payment, and cloud solutions. Retail companies such as CJ OLIVE YOUNG, a health and beauty retailer, and EMART Inc., an e-commerce platform, are also prominent. Woowa Bros. is a leading delivery app company, while MUSINSA 무신사 specializes in online fashion.

A notable characteristic is the strong presence of companies headquartered in Seoul, which serves as a central hub for many of these large enterprises. This concentration in the capital city suggests a significant cluster of e-commerce activity and related services within the metropolitan area.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
