About Shack

Shack is an AI-powered, fee-free auction app designed to revolutionize the second-hand marketplace. Designed in Switzerland and now available in the DACH region (Switzerland, Germany, and Austria), it connects buyers and sellers for authentic, pre-owned treasures. The platform is built for anyone looking to declutter their space, hunt for unique collectibles, or flip items for profit, all within a secure and transparent ecosystem.

By leveraging AI to create listings instantly from a single photo and focusing on local discovery via an interactive map, Shack makes buying and selling effortless, fast, and community-oriented. It champions sustainability by promoting reuse and combating throwaway culture, offering a modern, crypto-enabled alternative to conventional marketplaces.
