Why we built ShopStacks
Store builders give you a website. We wanted to give you a business.
Anyone can put up an online store in an afternoon. The hard part comes after: finding customers, sourcing products, and standing outwith the same fixed-price template as everyone else. Most new stores launch to an empty room, and auctions and marketplaces, the formats that actually create excitement, have stayed locked away for giants like eBay and Sotheby’s.
Our parent company, Turtles.com, spent years solving the deep problems of marketplaces: AI listings, payments, search, trust and safety, fulfillment, and a network of 29M+ shoppers and 2,000+ brands. That platform powers some of the fastest-growing marketplaces on the internet.
ShopStacks puts that same power in everyone’s hands. Launch a store, an auction site, or a full marketplace, with thousands of integrated auctions live on day one, your inventory synced everywhere, and 20+ selling formats you can stack like building blocks.
The name is the idea: start with a storefront, and stack on whatever your business needs next. Add auctions to your sneaker shop. Add a marketplace to your auction house. Add our sellers to your marketplace. There’s no ceiling, because the network underneath keeps growing.
Whatever you’re dreaming of, a boutique, an auction house, the next great marketplace, ShopStacks exists so you can launch it in a day and grow it for a lifetime. We can’t wait to see what you build.
