The problem
E-commerce founders and market researchers struggle to identify which products actually sell on competitor Shopify stores, resorting to manual URL tricks like appending sort parameters to collection pages. One founder shared a bookmarklet script just to one-click sort any store by best-selling, showing how underserved this workflow is. Existing research is slow, manual, and gives no historical or cross-store view.
Who it’s for
Dropshippers, e-commerce store owners, and market researchers
Market
2M+ Shopify merchants, with hundreds of thousands of dropshippers and e-commerce researchers as the core segment
Source: external_knowledge
Shopify powers roughly 2M+ active stores globally, and competitor/product research tools like Dropship.io and Minea target the large dropshipping and e-commerce research subset of that base, indicating a TAM in the hundreds of thousands to millions of potential users.
