Project Background

MarketPlace Monitor is a cross-platform deal-sourcing tool built for resellers and flippers. The app monitors user-defined search terms across popular online marketplaces - Facebook Marketplace, OfferUp, eBay, Craigslist, Gumtree, and more - and delivers instant push notifications when new listings appear. Being first to a deal is everything in the reselling business, and MarketPlace Monitor gives users that competitive edge.

Empiric Infotech developed the cross-platform mobile app, building a real-time monitoring engine with multi-marketplace integration and a tiered subscription system.
