# List of corporate groups and holding companies in Seoul

Tamtam tracks 59 corporate groups and holding companies headquartered in Seoul. This list ranks the 30 largest by number of employees on LinkedIn, led by Doosan, Samsung C&T Corporation and Hanwha Group. Their median headcount is 2,405. Half of them were founded in 1962 or later.

This selection of corporate groups and holding companies in Seoul includes large, diversified firms in industries such as industrial machinery, chemicals, and construction. Notable examples include Doosan, which builds power plants and industrial facilities, and Samsung C&T Corporation, active in engineering, construction, trading, and fashion. Hanwha Group operates in energy, aerospace, and finance, while LG Chem specializes in petrochemicals and advanced materials. SK Innovation focuses on sustainable energy technologies, and AMOREPACIFIC is a beauty conglomerate.

The companies listed here generally have a long history, with many founded in the mid-20th century. Doosan was established in 1896, Samsung C&T Corporation in 1938, and LG Chem in 1947. This suggests a prevalence of established enterprises rather than newly formed ventures.

## 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.
