Rocket Source
Wholesale Sourcing Analysis
Wholesalers and distributors can upload their entire supplier catalogs or price lists to instantly evaluate the profitability of thousands of products for Amazon resale.

Retail Arbitrage & Online Arbitrage Scouting
Retail arbitrage professionals use Rocket Source to analyze scanned or exported product lists from retail stores or online marketplaces.

Inventory Risk Mitigation for Large Brands
Major brands and large sellers utilize the platform to vet new products before large-scale purchasing.

Product Research & Category Expansion
Sellers looking to expand into new product categories can use supplier data to research market viability. By uploading potential product lists, they can assess average profitability, demand (via BSR), and competitive saturation within a new niche. This data-driven approach to expansion reduces risk and helps sellers strategically enter markets with proven potential for success.
