What APPG does

APPG (앱지) is a privately held South Korean custom mobile-application development firm founded in 2011 and headquartered in the Gangnam district of Seoul (business registration 899-87-01282). The company designs and builds native Android and iOS applications, mobile web, and corporate homepages, and lists more than 100 delivered client apps across verticals including O2O/e-commerce, education, finance and insurance, healthcare, IoT, real estate, travel, and government. Its named customer base includes Korea Electric Power Corporation (KEPCO), Hana Tour, Nice D&B, Unicef Korea, KG Mobile, and Ddang Ddang Chicken, indicating a mix of large Korean enterprises and mid-market accounts.

APPG's delivery stack is built on Java/SpringBoot with a Vue.js/Nuxt.js frontend, MySQL on CentOS Linux, and REST-based APIs, with distributed-processing capabilities (Hadoop, Redis, MongoDB, Zookeeper) for high-traffic applications. The firm also delivers specialized features including BLE integration, voice recognition, real-time chat, targeted push notifications, and video processing, positioning it for IoT and enterprise-grade deployments rather than purely consumer apps. Maintenance and managed-services revenue is supported by a strategic cloud partnership with KINX, which provides bundled hosting and server management.

The business model is professional services on a project-based, quote-driven pricing structure with multi-year maintenance contracts. Go-to-market is sales-led and domestically focused, running through a website quote form, a dedicated phone consultation line (1544-6821), and a Kakao channel; 6 in-house professional consultants/planners provide pre-sales strategic consulting. Additional revenue comes from a Startup/Government Support Program that combines free consulting with app-build execution, and from cloud hosting resold through KINX. The firm has no disclosed funding, no parent company, no M&A activity, and no international footprint, operating as an independent Korean custom-development shop.
