Dutch railroads

How NS builds a successful CRO strategy with Online Dialogue

Dutch Railways (NS) transports millions of passengers every day and is a crucial link in the mobility of the Netherlands. How do you build a strong experimentation and validation culture within such a large organization? Together with Online Dialogue, NS took big steps: from a pilot program to more than 145 experiments in one year.

DPG Media

A successful experimental program according to DPG Media

DPG media is the largest media company in the Netherlands. Through radio, television, newspapers, magazines, sites, apps and podcasts, they bring out news and entertainment. A dynamic field of work, but what about the culture of experimentation at one of the largest publishers in the BeNeLux?

'I chose mainly on person; I had a good click. Online Dialogue came across as flexible and looser, a culture that suits NS well. That personal click was ultimately the deciding factor.'

Jeroen Oosting - CRO strategist

'Because we lacked that knowledge ourselves, we sought cooperation with agencies. We have been working with Online Dialogue for a couple of years and that has not been a bad thing. They are very strong in data (science) and psychology and we needed a clear vision and method to get the organization on board.'

Joshua Krueger - Manager Gen Ai & Experimentation

'What I find strong is that we really did it together. As a result, it didn't become a study that disappears in a drawer, but something we can actively pursue.'

Kirsten van Benthem - Digital CX Manager

Better Bed

CRO at Beter Bed

We started at Beter Bed in 2014 and since then we have made great strides together, conducted interesting tests and most importantly gained wonderful insights about Beter Bed's visitors. How has Beter Bed developed in terms of CRO over the past few years? What were the obstacles and successes? What does their process look like? And what are the next steps?

EQOM

A successful CRO program at EQOM

EQOM has focused tremendously on CRO in recent years. EQOM is the European market leader in erotic products. The team has grown enormously in these years and, as a result, so has the number of experiments. So a huge growth, but how did they do this? How were we able to play a role in this? And how will they continue?

Vodafone-Ziggo

Learning-by-doing: 4 years of working together on VodafoneZiggo's CRO program

Learning-by-doing: how together we took VodafoneZiggo's CRO program to the next level. Their CRO program consisted mostly of gut feeling testing, but that has changed tremendously over the past 4 years....

Printing Deal

Data-driven redesign

In early 2020, we helped Drukwerkdeal.nl validate their redesign. Both the backend and frontend received a major upgrade. In 2023, they won the Experimentation Culture Awards. To provide insight into our work process and the redesign project, we asked Drukwerkdeal a few questions.

Beerwulf

Insights into online beer sales at Beerwulf with behavioral analysis

Beerwulf came to us asking if we could help map the behavior of their visitors. They wanted to understand their visitors better, but did not have a psychologist on staff. And besides, partly due to their explosive growth, they could use a fresh perspective.

KPN

KPN Case study: two years of A/B testing at KPN

Two years ago, we went to work for KPN to help with the data-driven optimization of their web shop environment. We started up not one, not two, but four A/B tests per week. This was the start of a long and valuable collaboration, with great results and many learnings as a result.
