Step 3 Merch manufacturer demand forecasting tool

Problem

When K-POP groups make comebacks, merch manufacturers (photocards, banners, lightstick accessories, etc.) struggle to predict demand, resulting in repeated overproduction (30-50% inventory loss) or underproduction (missed revenue). Reunion comebacks like I.O.I are especially volatile, making predictions based on existing fandom size data alone unreliable. Small-scale merch creators (solo sellers) spend an average of 5-7 days deliberating production quantities.

Solution

A SaaS that aggregates K-POP group comeback schedules, social media buzz volume, fan community activity, and historical merch sales data to forecast demand by merch category. Core features: (1) Comeback schedule-based demand forecast dashboard, (2) Real-time SNS/fan community buzz tracking, (3) Category-specific (photocards/banners/keyrings, etc.) production quantity recommendations.

Target: K-POP fandom merch solo sellers/small manufacturers (annual revenue $7,500-$75,000), idol MD planning agencies

Revenue Model: SaaS Monthly Subscription at ~$29/month (39,000 KRW, 3 artist tracking), Premium Plan at ~$59/month (79,000 KRW, unlimited + demand forecast Report). Comeback season spot Report at ~$37/each (49,000 KRW).
