ThredUP, the self-proclaimed “world’s largest fashion resale marketplace,” began as a pure multi-sided platform, matching sellers with buyers to trade their clothing directly. In an effort to create a better experience and more value for both sides, ThredUP pivoted to a consignment model taking more control over transactions (and, subsequently, more risk). The risk appears to be paying off as its latest “Resale-as-a-Service” launch allows brands and retailers to directly plug into the ThredUP platform to fuel their own businesses.
