The CRO Agency Behind
€500M+ in Additional Revenue
One integrated system — consumer psychology research, parallel A/B testing, and data-driven prioritization — built for e-commerce brands doing €5M+ per year.

The CRO Agency Behind 250+ of the World's Leading E-Commerce Brands






DRIP Agency is Europe's leading conversion rate optimization agency for 8- and 9-figure e-commerce brands. Through our integrated Conversion Optimization License — combining consumer psychology research, parallel A/B testing, and data-driven prioritization — we've generated over €500M in additional revenue across 250+ brands including SNOCKS, KoRo, Giesswein, and Kickz. Our 7-month Proof of Concept starts with a deep research intensive, then runs 6-10 experiments simultaneously using our Rapid Testing Protocol. We guarantee a minimum 10% revenue per user uplift in 6 months, backed by a database of 4,000+ documented experiments.
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 based on opinions and competitor copying instead of customer data
- Running 1-2 tests per month sequentially — maybe 12 per year
- Generic heuristic audits that apply the same checklist to every brand
- No system for compounding learnings — each test starts from zero
- Rising acquisition costs with no corresponding increase in revenue per visitor
The brands pulling ahead aren't working harder. They're working from a fundamentally different system.
Psychology-Driven Optimization, Not Guesswork
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.
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.
Best practices fail at scale because they're generic. They don't account for the fact that what drives a Kickz customer (status and belonging) is fundamentally different from what drives a KoRo customer (progress and comfort). When you understand these differences, your tests become surgical rather than random.

The Rapid Testing Protocol: Why Parallel Beats Sequential
Most testing programs run sequentially — one test at a time, wait weeks for results, move to the next. That means 1-2 tests per month. Maybe 12 per year.
We run 6-10 tests simultaneously using the same methodology Microsoft, Google, and Meta use internally. Randomization ensures each experiment remains independent — Microsoft found that meaningful test interactions occur in only ~0.002% of cases.
| Sequential | Parallel (DRIP) | |
|---|---|---|
| Time for 3 tests | 3 months | 1 month |
| Tests per year | ~12 | ~36+ |
| Revenue capture | Delayed by months | Immediate |
| Interaction errors | Untested combos ship anyway | Monitored, ~0.002% risk |
Now do the math:
If 2 of those 3 tests are winners generating €50K/month each in uplift, sequential testing leaves €200K on the table while you wait. Parallel testing captures that revenue immediately.
4,000+ Experiments Feeding Every Decision
Every test idea goes through our Weighted Impact Scoring system, evaluated against 25+ data points:
- Revenue exposure — where in the funnel does the test run?
- Scroll depth impact — how many visitors actually see the element?
- Research indicators — how strongly does customer data support the hypothesis?
- Implementation cost — how complex is the test to build?
- Historical performance — how have similar tests performed across our database of 4,000+ experiments?
The system is self-learning. As tests succeed or fail for your specific brand, the engine recalibrates. Typical agencies maintain a 30-40% test win rate. After 6 months with a calibrated system, win rates typically reach 55-65%.
