Case Study: 1stDibs modernizes retail media and scales sponsored listings with Topsort

1stDibs migrates 2,000 sponsored campaigns in months with Topsort

1stdibs, a leading luxury marketplace, needed to modernize its retail media infrastructure to better handle its complex, high-value catalog and provide more relevant advertising within its unique commerce environment. Their existing ad-serving solution was not built for this AI-driven complexity, so they partnered with Topsort for a new commerce intelligence platform.

Topsort implemented its AI-native auction infrastructure, enabling 1stdibs to run fast, real-time auctions with low latency and apply richer signals like semantic matching for more relevant ads. The migration of all sponsored listings traffic was completed within months, moving thousands of campaigns without disruption. This provided 1stdibs with a sophisticated foundation to explore new monetization surfaces and refine its advertising program.
