ZvG was a small scale webshop focusing on sustainable and high quality baby clothes. In the spring of 2020 Zoen voor Gust came to Marveltest with their case.

We conducted a thorough analysis of their current data and spotted a huge opportunity, when combined with our internal audience database. 

We were even so convinced that we took a shareholding within the company. Together with the team of Zoen voor Gust we profiled and segmented their audience. In combination with a powerful multichannel marketing automation we have reached great results, launching the company to a full grown scale-up. A not rare example of what we can reach together with our clients.
