Stash-Up is an innovative marketplace app designed for parents to buy and sell preowned school uniforms, ensuring affordability and sustainability. Founded by Mauricio Banados-Cornejo in York in 2019, Stash-Up aims to provide the best prices for quality uniforms and leverage a criteria-based recommendation system. As the company prepares for its UK launch, Stash-Up enlisted our team at York Community Consulting (YCC) to help achieve 10,000 email sign-ups from interested parents within three weeks.
