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.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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.
