Step 2 Trot fandom-based merchandise/performance commerce

Problem

The popularity of trot audition shows like 'Current Singers' has fueled rapid fandom growth among the 40-60 age demographic, but this group is unfamiliar with existing K-pop fandom platforms (Weverse, Bubble). They rely on fan cafes (Daum Cafe) to manually coordinate group purchases of merchandise, support wreaths, and fan meeting attendance, leading to frequent settlement errors and fraud. Fan cafe admins spend 20-30 hours per month on settlement and shipping management.

Solution

Provide a fandom commerce builder optimized for 40-60 age group UX (large fonts, phone ordering support, bank transfer payments). It handles the full workflow from group purchase creation to payment confirmation, settlement, and delivery tracking in one place, with built-in support wreath and ad group purchase features. Fan cafe board integration enables participation without separate registration.

Target: Trot singer fan cafe admins (ages 40-60, homemakers and Self-employed), running 1-3 group purchases per month
Revenue Model: Free Basic Plan (3 group purchases/month), Pro Plan $22/month (unlimited + auto-settlement), 2.5% transaction fee
Ecosystem Role: Infrastructure
MVP Estimate: 2_weeks
