The Problem

Portuguese parents spend €3,000-5,000 per child per year on clothing, toys, and gear — much of which is used for just 3-6 months before being outgrown. Currently, their options for reselling are limited to:

  • OLX/CustoJusto — generalist classifieds with no trust layer, no integrated payments, no shipping, and listings buried among everything from cars to electronics
  • Facebook Marketplace/groups — chaotic, no buyer protection, cash-only transactions
  • Vinted — great for fashion but not specialized for kids; no age/size filtering designed for parents, no bundle logic for outgrown wardrobes
  • Physical fairs — seasonal, local-only, time-consuming

There is no dedicated, trust-first, parent-focused marketplace in Portugal that makes it as easy to sell a bag of outgrown 6-12M clothes as it is to buy them.
