What Gcerti does
Gcerti (G-CERTI Co., Ltd. / 주식회사 지써티) is a Seoul-headquartered, privately-held ISO certification body and auditor training institute founded in 2011. The company is accredited under ISO/IEC 17021:2015 for management system certification and ISO/IEC 17024 for personnel certification, with recognition from both the International Accreditation Service (IAS) and the Korea Accreditation Board (KAB). Its core service line issues ISO management system certificates across 11+ standards covering quality (ISO 9001), environmental (ISO 14001), medical devices (ISO 13485), occupational health and safety (ISO 45001), food safety (ISO 22000), business continuity (ISO 22301), cosmetics GMP (ISO 22716), information security (ISO/IEC 27001), IT service management (ISO/IEC 20000-1), anti-bribery (ISO 37001), and customer satisfaction (ISO 10002). The second service line is auditor training, operating G-CERTI as a training institute under ISO/IEC 17021 and ISO 29993, including Lead Auditor courses, transition training for revised standards, and customized in-house auditor programs.
The company delivers services through a global network spanning 97 countries, with 26,324 cumulative clients, 37,780 issued certificates, and 2,267 registered professional auditors. Distribution combines direct enterprise field sales, on-site audit execution, and a channel network of 10 authorized Training Provider partners (branded GCT) located in Bulgaria, Iran, Japan, Lithuania, Malaysia, Mexico, North Macedonia, Serbia, Slovakia, and Turkey. Online self-service tools support certification applications, auditor lookup, certificate verification, and integration with IAF CertSearch. The revenue model is primarily subscription-recurring via multi-year certification cycles (initial audit plus surveillance and recertification audits), supplemented by professional-services revenue from auditor training programs and unit-priced promotional materials such as certification plaques.
Customer segmentation is vertical-driven across eight industries, with Manufacturing as the primary segment (food, beverages, cosmetics, machinery, electronics, automotive) and additional exposure to Construction, IT/Communications, Hospitality/Food Services, Financial/Insurance, Healthcare, Public Administration, and Education. Pricing is quote-based and varies with organization size, complexity, number of standards, sites, and audit days. The company is led by CEO Choi Kwon-kwon (최인권), with no disclosed parent company, institutional investors, or external funding.
