JEI

What JEI does

JEI Corporation (재능교육, 주식회사 재능교육) is a Seoul-headquartered private education company founded in 1977 by Sung Hoon Park, operating a global supplementary education franchise built around its proprietary JEI Self-Learning Method. The company's core technology is a computerized diagnostic system that evaluates each student's starting level, generates an Individual Progress Prescription Report (IPPR), and prescribes a sequenced path through programmed workbooks covering Math, Korean, English, Hanja, Reading & Writing, Problem Solving Math, Brain Safari, and critical thinking (Thinking Pizza). This diagnostic-to-prescription loop powers both the in-person JEI Self-Learning Classroom product and the free Self-Learning Online Diagnostic (ssro.jei.com), which feeds customer acquisition into the franchise network.

JEI serves children from preschool through middle school and their parents across 9+ countries (South Korea, USA, Canada, Hong Kong, China, India, Australia, New Zealand, Japan, Saudi Arabia). The company generates revenue primarily through franchise fees and monthly royalties from independently owned JEI Learning Centers, supplemented by workbook and curriculum materials sales and — more recently — by digital subscription revenue from the Cocoble coding education platform (cocoble.jei.com), which operates on a 7-day freemium trial with in-app monthly membership. AI features have been added across the stack, including AI handwriting recognition in the upgraded diagnostic system, AI-powered learning reports, an AI chatbot within Cocoble, and daily parent reporting via KakaoTalk.

The business is operated as part of the JEI Group (재능그룹), a diversified conglomerate with wholly owned subsidiaries spanning education (e-Academy, Self-Learning Teacher, Self-Learning Classroom, JEI University, JEI High School, JEI Middle School, Education Training Institute), media and retail (JEI TV, JEI English TV, JEI PLATZ, JEI Printing, JEI Distribution), and acquired brands (Scottie Go). The company is founder-influenced, privately held with no evidence of public listing or institutional investor ownership, currently led by CEO Baek Gyu-tae (백규태).
