Overview

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.

Services

Conversion Optimization

Conversion Rate Optimization is DRIP’s only service line and is delivered through three connected strategies: Predictive Consumer Research (mapping funnel touchpoints to user motivations using the 7 Psychological Drivers framework), Rapid A/B Testing (6-10 parallel experiments simultaneously, with statistical isolation modeled on Microsoft and Google’s internal factorial design), and Iterative Prioritization (3-5x more experiments per year than typical agencies). The team is platform-agnostic and works across Shopify, Shopify Plus, Magento, WooCommerce, custom builds, and headless commerce architectures.

FAQ

What makes DRIP different from other CRO agencies?

Four dimensions: scale (4,000+ experiments, €500M+ revenue impact across 250+ brands), methodology (psychology-first research using the 7 Psychological Drivers framework rather than best-practice checklists), velocity (6-10 parallel tests producing 3x the experiments per year), and specialization (exclusively e-commerce CRO). The published outcome is a 52.6% test win rate against a 20-30% industry average.

How does the Skin in the Game guarantee work?

What's the minimum traffic required for testing?

How long does onboarding take?

First A/B tests typically launch within 2-4 weeks. Month 1 is a Research & Strategy Intensive (40+ hours of session recordings, heatmaps, Category Entry Point identification, psychological driver mapping) delivered as a 20+ page report. Active testing begins month 2 with 6-10 parallel experiments.

Does the client need an internal dev team?

DRIP handles all test design, development, and QA in-house. Clients need an internal or external dev team to implement winning tests into the live site after experiments succeed. Ongoing collaboration requires less than 1 hour per week from the client, with bi-weekly strategy calls and monthly performance reports.
