Research to parallel testing to prioritization. Three loops, one accountable team.
CRO behind €500M+ in revenue.
Customer research, parallel A/B testing, and data-driven prioritization for e-commerce brands doing €5M+ per year.
You've tried everything. Revenue won't move.
You've redesigned the site. Twice. You've followed every best practice checklist you could find. You've copied what your fastest-growing competitors are doing. You've hired agencies who ran a few tests a quarter and called it optimization. And yet: your conversion rate is flat, your CACs keep climbing, and the gap between what you're spending on traffic and what you're earning from it keeps widening. The issue isn't effort. It's approach.
Testing on opinions
Hypotheses come from best-practice checklists and competitor copying, not customer evidence.
Slow test velocity
Sequential testing means maybe 12 experiments a year. Learning never compounds fast enough.
Generic audits
The same heuristic checklist gets applied to every brand, category, and customer state.
No learning memory
Every experiment starts from zero because wins and losses do not recalibrate the next decision.
CAC rises, RPU stalls
Traffic gets more expensive while revenue per visitor stays flat or moves backwards.
No accountable owner
Strategy, design, development, and analytics are split across teams. Nobody owns the revenue number.
The brands pulling ahead aren't working harder. They're working from a fundamentally different system.
See the systemWe optimize based on why your customers buy.
We don't optimize based on best practices. We optimize based on why your specific customers buy. Before touching a single test, we build a deep psychological profile of your audience. Using our proprietary Research Hub, we analyze thousands of data points — customer reviews, surveys, session recordings, heatmaps, competitor analysis — and map them against 7 Psychological Drivers. We also identify your Category Entry Points — the specific situations, feelings, and needs that cause strangers to seek out a product like yours. The more of these your funnel addresses, the more strangers you convert.
Progress
“Am I moving toward my goal?”
Curiosity
“Is there something I need to understand?”
Security
“Can I trust this brand?”
Status
“What does this say about me?”
Autonomy
“Am I in control of this decision?”
Comfort
“Is this easy and pleasant?”
Belonging
“Do people like me buy this?”
When we identified that "Initial Quality Perception" was a top Category Entry Point for Giesswein, we made targeted changes to their product pages. Two tests alone generated +€232,500/month and +€52,470/month respectively.

Why parallel testing beats
sequential testing. The
math, not the marketing.
Most testing programs run sequentially — one test at a time, wait weeks, move on. We run 6-10 simultaneously, the same way Microsoft, Google, and Meta do internally. Randomization keeps each experiment statistically independent.
One test at a time.
Revenue capture is delayed by months. Untested combinations ship anyway because nobody validated them.
6-10 tests, all live.
Revenue capture is immediate. Microsoft research found meaningful test interactions in only ~0.002% of cases.
If 2 of 3 tests are winners generating €50K/month each...
Velocity is the revenue lever.
Every test idea passes through
Weighted Impact Scoring.
Loudest voice doesn't win.
25+ data points feed the score. As tests succeed or fail for your specific brand, the engine recalibrates. Typical agencies hold 30-40% win rate. After six months with a calibrated system, win rates typically reach 55-65%.

Five engagements. The kind of revenue movement compounding actually produces.

Started at €2M/year with low AOV and no testing infrastructure. 350+ A/B tests later, RPU went from €2.01 to €4.99 (+148%), AOV from €29 to €51, and SNOCKS scaled past €50M annually.

DRIP Agency's Conversion Optimization License is a fully integrated CRO engagement covering consumer psychology research using the proprietary Research Hub, GA4 funnel analysis, A/B test design and development, QA across real devices via BrowserStack, statistical analysis using Frequentist methodology, ongoing strategy, bi-weekly calls, and monthly performance reporting with full revenue attribution. You don't need separate vendors for research, testing, and analytics — everything is unified under one system built on insights from 4,000+ documented experiments across 250+ brands.
To replicate DRIP Agency's system internally, you'd need at minimum a fullstack developer, a UI/UX designer, a QA engineer, a data analyst, and a CRO manager — that's €20K–€33K/month in salaries alone, before tools, training, and the 12–18 months to become fully operational. With DRIP, you get immediate access to the Research Hub, the 4,000+ experiment database, the Weighted Impact Scoring prioritization engine, and a team of 50+ specialists from day one. Brands like SNOCKS and KoRo chose this path and saw measurable results within the first months.
DRIP Agency runs 6–10 A/B tests simultaneously using our Rapid Testing Protocol — the same parallel testing methodology used internally by Microsoft, Google, and Meta. Over a 6-month engagement, most clients see 30–50+ experiments completed. This is 3–5x the velocity of traditional sequential testing programs, which typically complete only 12 tests per year. Brands like Kickz went from 2 tests/month to 6–10 parallel tests and saw conversion rates increase from 0.59% to 2.7%.
DRIP Agency works with any e-commerce platform — Shopify, Shopify Plus, WooCommerce, Magento, and custom builds. Our testing tools, primarily ABlyft and Kameleoon, integrate at the code level rather than through visual editors. This eliminates page speed degradation, ensures consistent rendering across devices, and produces more reliable test results. Our 10-person QA team validates every test across real devices using BrowserStack before launch.
DRIP Agency's standard engagement is a 7-month Proof of Concept. Month 1 is the Research & Strategy Intensive — a deep-dive into customer psychology, funnel analysis, and Category Entry Point identification that produces the foundation for your testing roadmap. Months 2–7 focus on ongoing optimization with 6–10 parallel A/B tests running simultaneously. Contact us for pricing details. The engagement is designed for e-commerce brands doing €5M+ per year.
DRIP Agency uses factorial experimental design — the same methodology used in controlled scientific experiments for decades. Each test splits traffic independently using randomization. If three tests run on the same page, each splitting 50/50, every visitor is assigned to one of eight possible combinations (2×2×2), ensuring each test's control and treatment groups are balanced across all other test conditions. Microsoft's research across thousands of online experiments found meaningful test interactions in only 0.002% of cases — approximately 1 in 50,000 tests.
Month 1 of DRIP Agency's Conversion Optimization License is dedicated to the Research & Strategy Intensive, during which the first tests are already being designed. First A/B tests go live by the end of Month 1. Most clients see their first winning tests within the first 2–3 months. For example, Oceansapart generated +€323,923/month within their first 6 months across 18 winning tests, while KoRo saw €2.5M in additional revenue in the same timeframe.
95% of brands that complete DRIP Agency's 7-month Proof of Concept continue with an ongoing engagement. The system becomes more effective over time as the Weighted Impact Scoring prioritization engine calibrates to your specific audience, industry, and funnel. Win rates typically climb from 40–45% in early months to 55–65% as the engine accumulates brand-specific data. SNOCKS, for example, has worked with DRIP continuously since 2019, completing 450+ experiments.
Yes. DRIP Agency, founded in Traunstein, Bavaria in 2019, works with e-commerce brands worldwide. Our team of 50+ specialists operates in English and German. Our client portfolio spans across Europe, North America, and beyond, covering verticals including fashion, food & beverage, health & wellness, sports, and home goods. The methodology is audience-driven, not geography-driven — the 7 Psychological Drivers and Category Entry Point frameworks apply universally across markets.
DRIP Agency's average client generates 8–12x return on their CRO investment. Unlike paid advertising where revenue stops when spend stops, improvements from A/B testing are permanent — a winning test continues generating incremental revenue indefinitely without ongoing cost. For example, a single Giesswein product page test generated +€232,500/month in additional revenue. Across 250+ brands, DRIP has documented over €500M in cumulative additional revenue through its 4,000+ experiment database, with a 52.6% overall test win rate.
