The company delivers English-language education to Korean working adults, business professionals, and — since 2022 — middle and high school students, operating nine physical learning centers across Seoul (Samsung, Gangnam, Jongno, Yeouido, Sinchon), Bundang, Ilsan, and Busan, supplemented by the Global Online Class (GOC) online platform launched in 2020.

The core product is a 20-level, 80-curriculum adult English conversation program delivered through a five-step blended method: multimedia self-study using self-produced sitcom content (Make it Big series) and an AI pronunciation analysis system; 1:1 speaking review with a personal Learning Coach; small-group native speaker Encounter Classes (average 2–3 students, max 4); native-speaker-led Complementary Class discussion; and unlimited Social Club sessions (55 minutes, average 15–20 participants, no frequency cap).

The business model is predominantly subscription-based monthly tuition starting at approximately 240,000 KRW/month with 3-, 6-, 9-, 12-, and 18-month commitments (longer commitments receive greater discounts), augmented by recurring corporate B2B contracts with customized budgets and learning management reporting. Marketing is multi-channel: website consultation booking, KakaoTalk Plus Friend chat, Naver Blog/Cafe, Facebook/Instagram/YouTube, free level tests, open house events, referral programs, and study-abroad exhibition partnerships. Customer acquisition, CRM, and notifications run on HubSpot and 퍼포마스 integrations. The brand carries ISO 9001:2015 certification (claimed as the only ISO-certified English Language Teaching school in the market) and Cambridge ESOL CEFR alignment certification (since 2007).
