Case Study: 1stDibs achieves sub-50ms sponsored listings auctions with Topsort

1stdibs achieves sub-50ms auction latency with Topsort

The customer, 1stdibs, is a luxury marketplace with over 2.6 million unique products. Their challenge was scaling their commerce media program, as their one-of-a-kind inventory made it computationally expensive to determine which sponsored products were eligible to compete in an auction. They migrated to Topsort's auction infrastructure to gain greater flexibility and performance.

Topsort redesigned the auction pipeline with targeted pre-filtering and semantic product matching to efficiently narrow candidate pools based on deep relevance rather than simple category matching. This solution allowed 1stdibs to migrate thousands of campaigns without interruption and now maintain reliable sponsored listings coverage with sub-50ms auction latency across their busiest discovery experiences.
