Case Study: Stapelstein achieves profitable D2C growth with Klar

Stapelstein boosts D2C revenue by 39% with Klar

Stapelstein, a German manufacturer of modular movement and play systems, faced the challenge of scaling its direct-to-consumer (D2C) channel across multiple international markets without a clear performance marketing infrastructure. The company needed to move beyond gut-feel decisions to understand regional budget allocation, identify new audiences, and maintain its brand values while growing profitably. They implemented Klar to gain this necessary clarity.

Using Klar's marketing mix modeling and data-driven attribution, Stapelstein was able to make weekly, data-informed decisions. This allowed them to reallocate budgets to the best-performing regions, discover a new adult audience for a key product, and confidently run a values-aligned Black Friday campaign by monitoring profitability in real-time. As a result, Klar helped Stapelstein achieve a +38% year-over-year revenue increase and a +44% improvement in contribution margin 3 (CM3).
