Curious about our work and how a QNTM solution may look like? Here are some of our clients, and a few words about what we have accomplished together.


ZERV is the mother company of a Danish sports retailer that covers 3 different kinds of sports – tennis, badminton and padel. They have smashing knowledge within racket sports and more than 22 years of experience.

Client problem

If you work with e-mail marketing, you know how long it takes to set up an e-mail flow with relevant recommendations. Imagine doing that for 13 different online stores at the same time.

This is an everyday occurrence for the Marketing Specialist at ZERV. It’s only possible with a personalization engine that delivers well-tailored recommendations – automatically and in real time.

Besides ZERV.dk, their portfolio also includes: Padelshoppen.com, Tennisshoppen.dk and Batmintonshoppen.dk – a total of 13 webshops across several countries including: Denmark, Sweden, Finland, Netherlands, and Germany.

Our solution

ZERV strives to provide a high level of customer service and a wide selection of world-class products. With such a wide selection of different products, they needed a solution to help them show the most suitable product recommendations for each visitor.

In November 2021, ZERV invested in Raptor’s personalization engine for web and e-mail. In a combination with Klaviyo, Raptor helps ZERV deliver the most personal and relevant product and content recommendations – on web and in mail and across all 13 webshops. From there it’s been full speed ahead!
