Sejoong operates two distinct businesses: a document and business-process outsourcing service that handles corporate paperwork, marketing materials, and workflow tasks on behalf of client companies, and a travel agency that arranges transportation, accommodation, and related services for travellers.
Corporate clients across various industries use the outsourcing arm to reduce costs and streamline back-office operations, while the travel division earns commissions by acting as an intermediary between travellers and service providers. The company is listed on KOSDAQ, South Korea's tech and small-cap exchange, and runs these two unrelated business lines under a single entity.
