The problem

Why many CRO programs stall after a year

At first, there are quick winners. Then the win rate drops, and the controller asks what the tests actually delivered. We see the same three reasons again and again. These are the three we solve differently.

REASON 01

Tests without customer understanding

If you test best practices, you find lucky hits. If you first understand why customers hesitate, you test with purpose. It shows in the win rate: At freenet, five out of eight tests succeeded.

REASON 02

Extrapolated wins

An uplift extrapolated to twelve months rarely survives scrutiny. We report results with confidence interval, runtime, and decay. Then finance believes the number, too.

REASON 03

The knowledge stays with the agency

When the contract ends, the progress ends. We build your team so it keeps testing on its own. freenet runs its testing program itself today.

Our approach

Conversion consulting and implementation from one source

Pure consulting ends with a recommendation nobody implements. Pure implementation builds what was ordered. We make the diagnosis, develop the test, and stay until it works. Three proprietary models make that repeatable. The Rapid Growth Engine makes it fast: research and tests run in parallel, the AI Research Engine delivers customer understanding in days instead of weeks, and a test takes 10 to 14 days.

Behavior Pattern Model

Translates proven behavior patterns like loss aversion or social proof into testable hypotheses. That turns a design opinion into an experiment.

7 Levels of Conversion

Finds systematically at which level customers drop off: from relevance to trust to usability.

G.R.O.W. Model

Measures how mature your organization is at experimentation and shows the next step. A well-known German fashion brand moved up two maturity levels with us.

Services

What we do for you as a CRO agency

Research and analysis

Web analytics, user interviews, usability tests, and jobs to be done. With the AI Research Engine, customer understanding takes days instead of weeks. We connect numbers and reasons, so hypotheses rest on understanding instead of gut feeling.

Hypotheses and prioritization

Every hypothesis is tied to a business goal. The roadmap is sorted by expected value contribution, not by gut feeling.

A/B testing

Concept, design, development, QA, and analysis. Client-side or server-side, with clean statistics and documented learnings.

Personalization

Segments built from real customer types instead of demographics. At computeruniverse, real-time personalization brought +18.2% revenue.

Relaunch validation

A relaunch without tests is a bet on revenue. We validate the critical steps before they go live.

Working together

Three models, one goal: Your team can do it on its own in the end

Whether you are building your own CRO team or outsourcing completely, we adapt the model to your organization. All models run on the Rapid Growth Engine. Billing is a fixed monthly price.

Enabling and in-housing: We build team, process, and tooling with you and support you until your people test independently.

Full Service Experimentation: Research, hypotheses, design, development, QA, analysis, and monthly reporting when you lack capacity of your own.

Embedded Experts: Experienced CRO and UX people work directly in your team when individual roles are missing.

Enterprise-proven: We work with IT, data protection, procurement, and multiple brands. Server-side testing and consent-compliant tracking are routine.

How a project runs

Five steps from analysis to rollout

Research and tests run in parallel. The first test can be live after about two weeks, depending on your approval process.

01

Analysis

Quantitative and qualitative methods show where and why customers drop off. With the AI Research Engine, in days.

02

Planning

Hypotheses are tied to business goals, prioritized, and planned by runtime and traffic.

03

Concept and design

Wireframes go through our Testing Board, then the design is created in your corporate design.

04

Implementation

Development, code review, and QA in the testing tool of your choice.

05

Analysis and rollout

We check validity and significance, document learnings, and roll out winners. Every test delivers insights, even a lost one.

FAQ

Frequently asked questions for a CRO agency

It finds out why visitors don't buy and tests solutions with A/B tests before they go live. With us, research, concept, design, development, and analysis belong together. The result is revenue that measurably comes from the tests.

A conversion consultancy delivers analysis and recommendations. A conversion agency implements tests. We do both. We make the diagnosis, build and evaluate the tests, and pass the knowledge on to your team. That way nothing gets lost in the handoff from recommendation to implementation.

We work with a fixed monthly price. Retainers start at €5,000 per month and are open-ended upward. We set the exact amount after discovery, once it is clear how many tests your traffic can support and which services you need. We calculate up front at what uplift a program pays for itself.

Often yes, and we help with that. Many clients start with us on full service and take over step by step. What an internal team rarely brings is the consumer psychology diagnosis and the statistical validation. We pass both on until your people can do it themselves. freenet and Consorsbank built their own conversion teams this way.

By three things. It grounds every hypothesis in customer behavior instead of best practices. It reports results with a confidence interval instead of extrapolated annual revenue. And it makes you more independent instead of more dependent.

You'll find eight criteria with questions to ask in the first call in our guide How to find a good CRO agency.

With the Rapid Growth Engine, the first test can run after about two weeks. At The Female Company it was 13 days. A single test takes 10 to 14 days, and reliable patterns show after about three months. For large enterprises with longer approval processes, the start takes longer. An enabling program is designed to run six to twelve months, until your team works independently.

Our way of working for fast learning. Research and tests run in parallel instead of one after the other. The AI Research Engine delivers customer understanding in days instead of months and draws on 15 years of documented experiments. A test takes 10 to 14 days, up to 50% faster to a valid result. It applies to all projects, whether a D2C brand or an enterprise.

Yes, with an adapted method. We test where the sample is large enough, measure intermediate steps, and add user research. We calculate up front which effects your traffic can even detect.

Yes. We are independent of tool vendors and work with the common platforms, client-side and server-side.

Yes. Server-side testing, consent management, and multiple brands and markets in one setup are standard projects for us with enterprises in telecommunications, banking, and retail.
