ThredUp

ThredUp is one of the world's largest online resale platforms for apparel, operating both a consumer marketplace and a Resale-as-a-Service offering for brands. Its centralised intake, sorting, and photography operation processes millions of secondhand garments annually, creating one of the largest standardised datasets of pre-owned fashion items at scale. This infrastructure is directly relevant to AI that must learn from real-world garment variation in condition, presentation, and provenance.
