JDKRUEGER&CO is a performance-based conversion rate optimization agency for e-commerce. The company does not operate a traditional agency model — no setup fees, no fixed costs, no hourly billing. Instead, JDKRUEGER&CO participates with 10 percent of the provable additional revenue generated by its own experiments — capped and fair.

The core is the proprietary Conversion Operating System (COS): 9 Engines — from analysis through hypothesis generation, development, QA, monitoring, experimentation, reporting, project management to success accounting. The knowledge from 18+ years and thousands of A/B tests is embedded in the system, not in a single person. That is why JDKRUEGER&CO can bear the risk.

Founded in 2019 by Jörg Dennis Krüger. Over EUR 210 million in provable additional revenue for clients. Thousands of tests conducted. JDKRUEGER&CO has received multiple awards: German Stevie Awards (2021 Gold + 2× Bronze, 2022 Gold), German Web Awards (2021 + 2022), HIPE Awards 2021 and Top Expert Erfolg Magazin (since 2022). Jörg Dennis Krüger is author of the pioneering work "Conversion-Boosting mit Website Testing" (2011), host of the "Conversion-Hacking Podcast" and sought-after speaker.
