Riverstone is a Hong Kong-based fast fashion supply chain management company that serves fashion retailers and brand owners primarily in the U.S., Australia, and the U.K. Riverstone provides end-to-end garment supply chain services, covering trend analysis, product design, raw material sourcing, manufacturing, quality control, and logistics. Key customers include Pretty Little Thing, Showpo, Cider, Boohoo, and Fashion Nova. Riverstone operates under three service models: OEM (manufacturing to customer specs, ~80% of revenue), ODM (designing and manufacturing for customers launching their own labels, ~17%), and OBM (selling under Riverstone's own "DOUBLE CRAZY" brand, ~3%). Garments are primarily produced at Riverstone's own factory in Ganzhou, China, capable of producing over 600,000 garments per month, supplemented by a network of contract manufacturers in mainland China. Riverstone uses a cost-plus pricing strategy, and the business is capital-light at the holding company level. Revenue is heavily seasonal, with roughly 46% generated in the August–December window. Riverstone's growth strategy focuses on technology investment — including generative AI for trend prediction and 3D digital sampling — geographic expansion into Latin America and the Middle East, sustainability differentiation, and reducing customer concentration risk.
