“Few people bridge the gap between marketing strategy and marketing technology as seamlessly as Gerben. He deeply understands both the fundamentals of the craft and the full implications of the martech stack. He asks the right strategic questions before any software is selected, preventing companies from buying a Ferrari to fetch a carton of milk, so to speak. Combine that with his calm presence, sharp insights and collaborative mindset, and you’ll understand why he's an invaluable asset in any conversation on marketing transformation.”

“Gerben was instrumental in designing a brand process enabling both global and regional marketing to create and deploy campaigns to support the business and strengthen the brand. He led a great international team of marketers across different locations, delivering global campaigns. And was also involved in strengthening our global creative agency and implementing a new brand platform. Job well done! And, he is very much liked and quickly became an important member of the Stokke family.”

“I had the pleasure of working with Gerben while he was helping Stokke plan out their marketing roadmap for the upcoming years. Gerben is a smart, well organized, insightful, and transparent partner that not only helps move the work through the system, but also helps it get better along the way.

“I have come to know Gerben as a valuable counterpart. Together with his team he implemented our CDP as the core of our customer program. He skillfully balanced business needs versus technical requirements and capabilities. Of course, with these kinds of implementations things can get strenuous and hectic with deadlines in view. But he handled that pretty well, at all times keeping an overview on how to move forward. And, what’s important as well, he is a nice person to work with.”

“Gerben helped us develop our CRM strategy and implement our VIP Club customer program. Since my role was still relatively new to me, I was especially grateful for Gerben’s hands-on coaching in CRM. What stood out was his deep experience not just on the marketing side of CRM but also his understanding of the IT setup and how to lead development teams—because he speaks their language. Working with him was a real pleasure.”

Jessica LangenbergCRM Manager @ IJsvogel Retail (Pets Place & Boerenbond)

“In nearly 10 years of working together, I’ve come to see that Gerben possesses some truly exceptional skills. From strategic deep dives to implementation, Gerben supports you in a practical, hands-on way. And he always delivers on time and within budget. Reliability is one of Gerben’s core values. He ensures progress with a clear roadmap and implementation plan. Hands-on. And, above all, it’s just a pleasure working with Gerben as a person. A man with a big heart.”

“One of the qualities I truly value in Gerben is the high level of quality he brings to strategy development, execution planning, and benchmarking service design projects. His proposals are always clear and to the point, with an eye for the big picture, the essentials, and the relevant details. He crafts his proposals and presentations as narratives—a real asset when selling strategies, ideas, and plans both internally and externally.”

Brian OostenbrinkCXO The Valley

“Working with Gerben on GM's Cadillac, Corvette & HUMMER accounts was an incredible experience. At Bookmark, he developed several brilliant, impactful strategies. Gerben understands client service, and when he combines that with his strategic strengths in loyalty marketing, customer engagement, lead generation, and brand activation, he becomes an invaluable asset to any company.”
