Moyle

Moyvle — a US-focused K-fashion marketplace app built with React Native, delivering fast checkout, real-time tracking, and clear sizing for Korean brands.

Unilink

One-liner: A multilingual admissions platform where students discover programs, apply with a single profile, and chat 1:1 with university admins. Universities manage everything via a role-based admin panel.

스쿨허브(Schoolhub)

SchoolHub is an end-to-end learning management platform designed for schools, academies, and after-school programs. It streamlines daily operations—course creation, term/semester planning, rosters, attendance, assignments, grading, announcements, and parent communication—into a single, intuitive workspace. With real-time updates and a clean, mobile-friendly UI, SchoolHub helps teams teach more and administrate less.

Graze(그라제)

Graze is a community-driven live-commerce platform for Korea: sellers host real-time shopping shows, viewers buy instantly, and everyone connects through forums, curated videos, and seller discovery. It offers broadcast schedules, guides, and low-cost messaging tools, plus companion Android apps for viewing and streaming.

Korea Medis

KoreaMedis is a medical-tourism platform that helps international patients compare Korean hospitals, get transparent treatment plans and costs, and book care—backed by concierge services like interpretation, visa, and travel support. Mobile apps on iOS/Android extend the same experience on the go

Zatam(자탐)

Zatam is a K-12 education community and discovery hub in Korea. Parents and students share tips and admissions info in topic boards, browse curated study resources and YouTube playlists, register for info sessions, and find academies via a searchable directory. The site supports social login (Kakao/Naver) and has a language selector for a multilingual experience.

Meflex(Crypto wallet)

Meflex is a simple, secure, multilingual Web3 wallet that lets users store, send, and receive crypto across popular chains—featuring 1-tap QR transfers, human-readable addresses (ENS/UD), WalletConnect DApp support, and biometric protection.

HelloCreator(voli)

HelloCreator was a creator-tools concept showcased at DMTS 2022 (KINTEX)—a demo of AI-assisted content creation workflows (especially audio/sound for creators) and a community hub concept. The prototype was exhibited, but the service is currently inactive

Koing AI (코잉)

Koing AI (코잉) is a no-code platform that lets teams design, build, and launch full-stack web apps using a visual editor—drag-and-drop UI, data models, and workflow automations—without writing code. Apps ship with auth, RBAC, i18n, and one-click deploys.
