JDKRUEGER&CO delivers conversion optimisation for online shops. Jörg Dennis Krüger, known as "Der Conversion Hacker®", finds where a shop loses buyers and shows what it costs in euros. What wins goes live fast. Where traffic allows, an A/B test proves the effect. Founded in 2019 by Jörg Dennis Krüger, who has worked in conversion optimisation since 2006: at QUISMA (GroupM), Sixt and Regiondo, and since then directly for shops. JDKRUEGER&CO works from Berlin and Bogotá, on every shop system. Awards for JDKRUEGER&CO: German Stevie Awards (Gold in 2021, 2022, 2023 and 2025, two Bronze), German Web Award 2021 and 2022, HIPE Award 2021, and Top Expert in Erfolg Magazin every year since 2021.
