Online-Fensterbank.de is now Germany’s market leader for custom-made window sills – but just three years ago, the company was still reliant on physical sales reps and operated mainly as a supplier to other brands. Through a full application of the h1gh Performance Framework, we helped Ofschenka completely transform its business model: from offline B2B sales to a powerful direct-to-customer platform via an intelligent product configurator. This radical shift not only enabled scalability and automation but also opened the path to multi-million euro revenues.

Creative Focus & Challenges
Scaling a Niche Product into a National Brand
Unlike traditional consumer products, window sills are complex and technically demanding to sell online. By rethinking every touchpoint – from product explanation to configurator UX and performance ads – we removed friction, created trust, and enabled conversions at scale. What made this case special: We didn’t just run ads – we helped reshape a business. Our work turned a once hidden supplier into a digitally dominant brand – with full control over pricing, customer acquisition, and long-term brand equity.

Strategic Approach & Results
We implemented the full six-phase h1gh Performance Framework – aligning brand, business model and performance.
Phase 1 – Fundament: We conducted a full brand, market, and channel audit to evaluate the business potential beyond the old sales structure. Phase 2 – Creatives: We created performance-focused digital assets and optimized the web presence to reflect value, clarity, and trust in a complex product category. Phase 3 – Setup: A complete infrastructure for data tracking, funnel segmentation, and cross-platform conversion tracking was established. Phase 4 – Proof: We initiated controlled growth with various ad campaigns and began identifying scalable paths through structured A/B testing. Phase 5 – Optimization: We continuously refined budget allocation, target audiences, landing page funnels, and messaging based on granular performance data. Phase 6 – Performance Loop: Today, we are in the advanced optimization loop, running targeted ad campaigns across channels – fueling continued growth and efficiency. Through the strategic implementation of the h1gh Performance Framework, Online-Fensterbank.de experienced significant growth in both revenue and brand awareness. The company successfully transitioned to a fully digitalized sales model, serving both B2B and B2C audiences via an intuitive online configurator. Brand visibility increased drastically across digital channels, and the consistent performance of campaigns resulted in a high and stable ROAS. Within just three years, Online-Fensterbank.de established itself as the market leader for window sills in Germany, with a scalable business model and a strong foundation for long-term growth.
