The business model combines a consumer e-commerce marketplace with a logistics-heavy consignment operation and a B2B resale infrastructure platform. On the consumer side, the company acquires inventory from individuals via prepaid Clean Out kits, centralises sorting, grading, authentication (for luxury items), photography, and listing, then sells qualifying items via its marketplace. Value is created for buyers through access to lower-priced secondhand fashion with retail-like shopping features, and for sellers through a low-effort way to monetise unwanted clothing.

On the B2B side, the company repackages its processing facilities, technology, and marketplace capabilities as Resale-as-a-Service (RaaS), allowing fashion brands and retailers to offer branded resale, trade-in, and clean-out programmes. This creates value for partners by enabling them to participate in resale and circular fashion without building their own logistics, technology, or customer-facing resale channels, while driving incremental inventory and transactions back into the company’s system.

ThredUp Inc. is a United States-based online consignment and thrift marketplace focused on women’s and children’s apparel, shoes, and accessories, supported by centralised intake, processing, and AI-enabled search. It operates a consumer-facing e-commerce site plus specialised programmes such as a luxury resale vertical and a Clean Out mail-in service for individual sellers.

The company generates revenue primarily by retaining a margin on each item sold through its marketplace and luxury vertical, and by charging brands and retailers for resale infrastructure and white-labelled resale shops through its Resale-as-a-Service (RaaS) offering. Its main customers are individual buyers and sellers of secondhand fashion, and B2B partners (brands/retailers) that want to run branded resale programmes without building their own logistics and technology stack.
