Dealicious was founded in 2011 by CEO Kim Jun-ho, a software developer, and after several business model pivots — including a brief foray into social commerce — launched Sinchang Market in 2013, digitizing the Dongdaemun clothing wholesale district's traditional late-night in-person trading activities.
Sinchang Market is a two-sided vertical commerce platform that brings wholesale product promotion, search, ordering, and payment fully online, and has grown to enroll over 80% of Dongdaemun wholesale operators.
The revenue model is built on advertising and subscription services rather than transaction commissions: Sinchang Ad (wholesale-side advertising), Sinchang Membership (wholesale subscription), and Plus Membership (retail subscription) form the three core revenue pillars.
Additional services — including Sinchang Delivery (end-to-end sourcing and fulfillment), Sinchang Studio (product photography and listing support), and S.O. Plus (a cloud logistics ERP) — deepen ecosystem lock-in and raise switching costs.
As of H1 2026, the platform has 23,000 approved wholesale members and 400,000 approved retail members, hosting 2 million new product listings annually, generating 21.5 billion product exposures per year, processing 50 million orders annually, and accumulating approximately KRW 5 trillion in lifetime GMV.
In 2025, the company reported a contribution income of KRW 24.9 billion against a contribution margin of 81.1%, implying that each KRW 10 billion revenue increment yields approximately KRW 8.1 billion in additional operating income — a notably leveraged earnings structure.
The company has internalized AI-powered ad optimization and image search, with management reporting approximately a 2x improvement in ad click-through rates post-AI integration.
Domestic competitors include Linkshops and Modu's Sinchang, though industry observers assess that Sinchang Market maintains a commanding lead in wholesale operator penetration.
Globally, the company operates Sinchang Delivery to 91 countries following its Japan launch in 2022, with Taiwan and Hong Kong targeted for addition in 2026.
