The education providers in Seoul are predominantly large higher education institutions. These include Seoul National University, a leading academic community fostering scientific and technological progress, and Hanyang University, a private research university known for engineering and architecture. Other notable institutions are Korea University, a prestigious university offering a wide range of courses, and Sungkyunkwan University, a top-ranking private university supported by Samsung.
A clear pattern among these companies is the strong presence of established universities, many with long histories. While most are focused on traditional higher education, there are also e-learning providers like Engoo, which offers 1-on-1 language lessons, and Ringle, a platform for conversational English practice. This indicates a diverse educational landscape within the city.

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.
