The Problem
Sustainable Choices Weren’t Always Easy
While resale platforms were booming, most either:
• Focused on luxury (Vestiaire Collective)
• Lacked local relevance or felt too impersonal
Shoppers wanted a fast, easy, trustworthy way to buy and sell second-hand items locally—without the hassle.
