Reusable Cup Inventory Tracker SaaS

3.70

Derivation Chain

Step 1 Starbucks reusable cup open-run / limited-edition goods craze
→
Step 2 Limited-edition goods resale market activation
→
Step 3 Limited-edition inventory and price tracking tool for resellers and small distributors

Problem

Individual resellers and small-scale distributors who resell franchise limited-edition goods (reusable cups, collaboration merchandise, etc.) spend 2-3 hours daily manually monitoring communities and secondhand platforms to track store-by-store inventory and resale prices. Failed open-run attempts mean missed acquisition opportunities, and misjudging prices leads to repeated losses of $7.50-$37.50 per item.

Solution

Provides a store-by-store limited-edition inventory dashboard via franchise official app/community crawling + automatic price tracking on Bungaejangter and Karrot (Korean secondhand platforms) + open-run schedule alerts and price change push notifications, reducing reseller decision-making time by 90%.

Target: Limited-edition goods resellers aged 20-30, individual sellers trading 10+ items/month and small-scale secondhand distributors
Revenue Model: Premium SaaS Monthly Subscription at $14/account, Free tier (track 3 brands), Pro tier (unlimited brands + price alerts)
Ecosystem Role: Supplier
MVP Estimate: 2_weeks
