350+ · A/B tests run
Our team picks the ideas most likely to win, builds them, QAs them and reads every test inside Apex. You approve the designs and watch the dashboards. You don't touch a test. And because our people run the machine, it comes with a guarantee: at least 10% more revenue in under six months, or month seven onward is free.
For online shops from €100k a month. A free 30-minute call with the team.












Sound familiar?
You know A/B testing pays. You've seen the case studies. But a real program needs research, odds on every idea, design, code-level builds, QA on real devices and statistics nobody gets to peek at.
In-house, that's at least a CRO manager, a designer, a developer, a QA engineer and a data analyst, and 16 to 24 months before the machine runs. Then your CRO lead quits, and the knowledge walks out the door.
Prediction-based experimentation, run end to end by our team of 70+: strategists, behavioural psychologists, data analysts, designers, developers and a QA team. Four steps, repeated every month.




The first month is research. Reviews, surveys, support tickets, your competitors' reviews, ten analyses of your funnel and 40+ hours of session recordings and heatmaps. We look for where revenue leaks, and why. You get a 20+ page report, and every idea on your list is written as if, then, because.
Apex by DRIP, our own testing tool, gives every idea a Likelihood to Win, based on one of the largest A/B test databases in e-commerce: 4.3 million tests from 151,000 shops. Together with revenue exposure and effort, that becomes a weighted impact score that decides what gets built first. It's recalibrated every two weeks on your results.
Every test gets a brief and 3 to 5 designed variants for mobile and desktop that you approve. We build in code, not in a visual editor, and our QA team checks each variant on real devices. Then six to ten tests run in parallel on clean 50/50 splits.
We measure revenue per visitor, with the statistics fixed before launch: 80% confidence, 80% power, no early stopping. Winners ship. Every result, including the 40 to 50% that come back negative or unclear, gets filed by buyer motivation and friction point, so the next round of ideas starts with better odds.
That's the short version. The full method, phase by phase, is on the process page.

Very little. You approve each test's designs before anyone writes code, and you watch the results on your dashboards. Our team does the research, the ranking, the builds, the QA, the launches and the reading of every result, all inside Apex. The install is one line of code on your site.
Everything a testing program needs, from one team of 70+ people: strategists, behavioural psychologists, data analysts, designers, developers and a QA team. That covers the research, the ranked backlog, test design and development, QA on real devices, the statistics, the reporting and a call every two weeks. Apex by DRIP, our own testing tool, is included, so there's no separate tool subscription.
At least 10% more revenue in under six months, or month seven onward is free. What counts as uplift, how it's measured and what happens if we miss is written down in plain language. We can promise it because more than 50% of our A/B tests win, across 4,000+ documented experiments. It stands because our team runs the program, which is why it comes with Done for you.
We ramp up until six to ten tests run in parallel at any time. By month three, most shops have run more experiments than most brands ship in a year. The exact pace depends on your traffic and on how many pages carry enough revenue to test on.
In month one the research is done, the plan is scored and the first tests are live. A result counts once a test reaches the sample size fixed before launch, not earlier. Month six is when the guarantee comes due and the lift gets measured.
We work with online shops, whatever they run on: Shopify, Shopify Plus, WooCommerce, Magento, headless and custom storefronts. Every test is built at code level rather than in a platform's visual editor. How your stack is set up is one of the first things we look at on the call.
Everything Apex learned about your shop, every result and every document, is yours and stays readable. What enters the shared model is the pattern, never your copy, your creative or your numbers.
If you don't have a testing team, or you want the guarantee, Done for you. If you already have people who can design, build and launch tests, Done with you gives them our research, the ranked ideas and the odds, and your team runs the program in Apex. On the call we'll tell you which one fits your shop.
Book a call with the team and tell us about your shop. We'll talk through where it stands, where you want it to go, and how we'd get you there. If working with us isn't the best return on your money, we'd tell you rather than take it.
30 minutes, and you'll know exactly where your shop stands.
