Swap.com is an online thrift and consignment store based in the United States. Its technical work spans proprietary e-commerce technology, logistics and fulfilment technology, and an online marketplace platform, supporting both the buying and selling sides of the business.
The company's marketplace allows shoppers to filter and buy like-new, pre-owned clothing for women, men, children and babies, as well as non-apparel items such as toys, books, films and home decor. The platform is described as one of the largest online consignment stores in the US, and the company reports that millions of items have been kept out of landfills through its operations.
On the seller side, users ship consignment items to the company's warehouse and logistics centre, where the items are listed for sale online; original sellers are paid when their items sell. Engineering work therefore covers both a consumer-facing marketplace and the fulfilment systems that process and list inventory at scale.
Swap.com states a mission-driven focus on promoting sustainable shopping practices, serving a community of thrifters and budget-conscious shoppers, and simplifying the process of buying and selling secondhand goods.
