About thredUP

thredUP is the world’s largest fashion resale platform, inspiring a new generation to think secondhand first. The company has spent the past 10 years reinventing resale, building a marketplace and infrastructure now poised to power the $50B resale economy and usher in a more sustainable fashion future. Millions of consumers use thredUP as the easiest way to sell their clothes and shop over 35,000 brands at up to 90% off — online, in stores or via “try-before-you-buy” Goody Boxes. Backed by world-class investors, thredUP designed a resale engine that has redistributed nearly 100 million unique garments from closets across America and is now powering resale for the broader fashion industry via its Resale-As-A-Service (RAAS) platform.
