Secondhand and recommerce pricing engines (buy-back, trade-in and consignment valuation); days-to-sell and sell-through forecasting by brand, size and condition; brand-level residual-value benchmarks comparing realised sale price to original ask; consumer discretionary demand nowcasting from completed-sale volumes; catalogue enrichment and product matching across marketplaces; and labelled training data for comps-relevance and price-estimation models — the sold-price-plus-cleaned-relevance pair set is directly usable as supervised data.

Coverage spans US; Internet & Direct Marketing Retail, Apparel, Accessories & Luxury Goods; alternative, price; equities.
