Building professional tools for serious resellers and arbitrage traders.
PowerBuyer was born from a professional reseller's frustration: native marketplace search tools on platforms like Etsy, Mercari, and Poshmark are challenging for arbitrage. Slow, clunky filters. Missing new listings. Wasting hours clicking through irrelevant results. Losing deals to faster competitors.
Our mission is to give professional resellers a decisive competitive edge. We built PowerBuyer for people who treat online arbitrage as a real business—not casual browsers, but professionals with profitable niches who need to be FIRST to see new listings.
Whether you flip vintage clothing, sports cards, video games, electronics, or collectibles, PowerBuyer is designed to save you hours and maximize your profit margins. Because in arbitrage, speed isn't just convenient—it's everything.
In arbitrage, being first means everything. We're obsessed with speed because your profit margins depend on seeing opportunities before your competition.
Every feature is designed for serious resellers who know their niche. We don't build for casual browsers—we build precision tools for people who treat this as real work.
Your data is your business. We take privacy and security seriously, using industry-standard encryption and never selling your information.
The marketplace landscape is constantly evolving. We're committed to staying ahead of the curve with new features and integrations.
No hidden fees, no surprises. We believe in honest, transparent pricing and clear communication with our users.
We're building PowerBuyer for the long haul. Our focus is on sustainable growth that benefits both our users and our team.
PowerBuyer started in 2024 when our founder—a professional vintage clothing reseller—got tired of losing deals. Hours wasted manually checking Etsy, Mercari, and Poshmark. Missing listings posted 10 minutes ago. Watching competitors snap up inventory first. The breaking point came after losing a $400 profit flip because someone saw it first.
PowerBuyer is designed for professional resellers across niches—vintage clothing, sports cards, video games, electronics, collectibles, vintage jewelry. We've built advanced filtering, multi-marketplace monitoring for Etsy, Mercari, and Poshmark, fast Telegram alerts, and automation features that treat arbitrage like the serious business it is.
Today, professional resellers depend on PowerBuyer to discover profitable inventory faster than their competition. Every feature we build is designed to save you time and maximize your profit margins.
