What Epirus does
Epirus (EPYRUS EbookClub) is a South Korean digital e-book platform operated by Blue Mountain Soft Inc. (주식회사 블루마운틴소프트), a private corporation headquartered in Yeongdeungpo-gu, Seoul. The service, live since 2010, distributes Korean-language genre fiction — primarily romance (로맨스), fantasy (판타지), and martial arts (무협) novels — with a separately gated adult fiction section (레드소설) requiring age verification. Content is delivered through a web storefront (ebookclub.co.kr) and consumed via a proprietary Windows-only reader application (32-bit and 64-bit) that auto-installs via ActiveX; users authenticate using email or social login (Naver, Kakao, Apple).
The platform's technology stack centers on a DRM-protected content library, an internal virtual currency called EPYRUS Money (1:1 with KRW), and a loyalty points system (Epirus Points). The business model combines three monetization layers: bundled purchase tickets (10 or 20 books for 32,000-66,000 KRW, 1-year validity), time-limited rental tickets (up to 60 days, 8,100-16,200 KRW), and subscription-style free-use book passes (1/7/30 day windows at 3,000-22,000 KRW). Pricing varies by genre category, with romance and fantasy/martial arts sold as separate product lines.
Distribution is exclusively direct-to-consumer via the company's own e-commerce site within South Korea, with no mobile app, public API, or international localization. The headcount is reported at 1-10 employees, no external venture funding is disclosed, and the representative (CEO) is Gu Sang-mun (구상문). Customer service operates on Korean business hours (weekdays 9am-5pm KST), and the current terms of service have been in force since 2016-06-16.
