Online consignment and thrift store for buying and selling high-quality secondhand clothing.
ThredUp is an online consignment and thrift store that enables customers to buy and sell high-quality secondhand clothing. The platform offers over 55,000 brands with up to 90% off retail prices, featuring 50,000+ daily new arrivals and over 4 million items available at any time. They also power resale programs for major retail brands like J.Crew, Madewell, and Reformation.
ThredUp was founded with a mission rooted in circularity and sustainability, aiming to transform the way the world shops by making secondhand the first choice for consumers. Their goal is to keep clothing in circulation and combat the harmful effects of disposable fashion. The company has been operating for nearly two decades with the vision of turning secondhand shopping into a mainstream practice.
ThredUp's impact extends far beyond just selling clothes - they are actively combating fashion waste and environmental damage caused by fast fashion. The company has processed 230 million secondhand items, prevented 1.1 billion pounds of CO2 equivalent emissions, saved 11.5 billion gallons of water, and conserved 2.1 billion kWh of energy. Through their circular business model, 90% of items sent to ThredUp find new homes, significantly reducing textile waste that would otherwise end up in landfills.
ThredUp creates environmental impact through their circular business model that keeps clothing in circulation rather than allowing it to end up in landfills. By facilitating the buying and selling of secondhand clothes, they extend the lifecycle of garments and reduce the demand for new clothing production. Their Clean Out service makes it easy for consumers to send in unwanted clothes, which ThredUp then processes, photographs, and resells.
This circular approach has generated significant measurable outcomes in environmental conservation. The company has prevented over 1 billion pounds of CO2 equivalent emissions while saving billions of gallons of water and kilowatt hours of energy that would have been used in new clothing production. Their model demonstrates that 90% of items sent to them successfully find new owners, proving the viability of fashion circularity at scale.
