JDKRUEGER is not an agency. We run a Conversion Operating System with 9 engines, from the first analysis to the rolled-out winner. You pay no hourly rate and no retainer: you pay 10% of the proven added revenue.
You pay 0 euros setup and no monthly fees. Our fee is 10% of the proven added revenue, measured as a direct A/B test comparison between control and variant. Costs only arise once the variant actually generates more revenue.
We work with e-commerce shops generating at least 100,000 euros in monthly net revenue, prioritized from 300,000 euros/month. The model works with Shopify, WooCommerce, Magento, Shopware, and other shop systems, but not with pure marketplaces without their own shop.
Within 14 days we implement our system, launch the first optimizations, and show measurable results. After that, you decide: a success-based partnership or walk away at no cost.
