What Gift Letter does

Gift Letter (기프트레터, legal entity Gift N Co., Ltd., founded May 2013, Seoul) is a Korean mobile commerce intermediary specializing in mobile coupons and digital gift vouchers for both B2B and B2C use cases. The company's core platform handles issuance, authentication via barcodes and unique coupon numbers, distribution, customer service, and settlement across a network spanning KakaoTalk Gift, Naver Smart Store, all three Korean telecom operators (SK, KT, LGU+), major e-commerce marketplaces (Gmarket, Auction, 11th Street, Coupang, WeMakePrice, Interpark, TikTok), department stores (Lotte, Hyundai, Shinsegae), and corporate welfare platforms. Its O4O (Online for Offline) platform bridges digital gifting with physical retail redemption, while the GiftN Biz-Mall sub-brand serves as a dedicated B2B e-commerce portal for corporate customers.

Gift Letter generates revenue primarily through transaction fees on mobile coupon issuance and distribution, marketplace commissions on brand gift voucher sales, and recurring subscription-style B2B solution contracts covering issuance, settlement, and admin tooling. Its product portfolio includes the core Mobile Coupon Service, B2B CRM marketing admin tools, the O4O platform, bulk SMS/MMS infrastructure, integrated management systems, and the CouponBay subsidiary. The company holds registered Korean software copyrights for its issuance system, Biz-Mall, and BBM Voucher Shop, plus INNO-BIZ and Technology Guarantee Enterprise certifications.

As of March 2026, Gift Letter announced a stock-for-stock merger with KOSDAQ-listed Hyper Corporation, with Gift Letter as the absorbed entity and completion set for April 30, 2026. The company operates primarily in South Korea with a legacy Indonesia presence (since 2016). Representative Director Seok Bong-sang (석봉상) leads the company. Notable enterprise clients and brand partners include Samsung Electronics, CGV, Lotte Department Store, Hyundai Department Store, SK/KT/LGU+, DoubleTree by Hilton Seoul Pangyo, and Ambassador Hotel Group, alongside a broad catalog of 100+ SMB brand partners spanning F&B, hospitality, retail, automotive, and wellness categories.
