About

97% of your website traffic isn't ready to buy today. If your international expansion strategy is just "translate the store and send cold traffic to a Shopify product page," you are burning cash and killing your margins. As an E-commerce Growth Consultant fluent in English, German, and French, I build and execute market-specific funnel architectures that capture immediate demand while systematically converting the remaining 97% of the market. 🌐 SPECIFIC MARKET EXPANSION CORRIDORS: I exclusively partner with Shopify brands operating in or expanding through these 2 routes: 1️⃣ French brands looking to launch and scale profitably in the DACH region. 2️⃣ German / DACH brands looking to expand and capture the French market. 📈 Recent Track Record (Marwona): Market Launch: Successfully launched the French market, achieving a 6.5 ROAS (Global ROAS stabilized at 4.0). Acquisition Efficiency: Engineered a localized funnel strategy that reduced and maintained CAC at 65€ against a strict target of 100€. How I work with brands: I don't just give advice; I deploy a proprietary framework tailored to local consumer psychology, regional payment trust signals (like Kauf auf Rechnung), and specific multi-step acquisition funnels directly on your Shopify ecosystem.
