DRIP Agency is a Germany-based conversion rate optimization agency founded in 2019 by Samuel Hess (Chief Experimentation Officer) and Fabian Gmeindl, registered in Traunstein, Germany. The team has grown to 70+ specialists across CRO managers, growth marketers, behavioral scientists, designers, developers, and QA. The positioning centers on psychology-driven A/B testing rather than best-practice checklists, with rapid parallel experimentation (6-10 simultaneous tests) modeled on the factorial design approach used internally by Microsoft, Google, and Meta. Reported lifetime stats include €500M+ in additional revenue generated across 250+ brands, 4,000+ experiments run, a 52.6% test win rate against the 20-30% industry average, and 95% client retention. A “Skin in the Game” guarantee promises measurable uplift on conversion rate or AOV within 6 months. Public client work includes SNOCKS, KoRo, Giesswein, Blackroll, Hello Fresh, AG1, The Body Shop, Schiesser, Horizn Studios, Kickz, Coop, Oceansapart, and Waterdrop.
