Founder, CEO and CTO with 25+ years of experience building, scaling, and exiting SaaS, marketplace, and platform-driven companies. I am known for combining strategic thinking with technical depth, leading teams through complexity, and turning ambiguity into scalable products and businesses. Since 1999, I have focused on building online platforms that help people make better decisions by connecting them with relevant products, services, and information. My work consistently sits at the intersection of technology, commerce, and human behavior, with a strong emphasis on clarity, usability, and long-term scalability. As co-founder and CTO, I helped build M4N (Money For Nothing), the first and largest affiliate marketing SaaS platform in the Netherlands. I led the technical vision and engineering teams of a high-scale, transaction-driven platform serving tens of thousands of publishers and advertisers. M4N was listed in the Deloitte Fast 50 for four consecutive years and facilitated hundreds of millions of euros in annual consumer spending before being acquired in 2011 by Zanox (now AWIN). Following the acquisition, I led the technical integration of M4N into Zanox’s international platform, coordinating cross-border teams within a large enterprise environment. In 2013, I founded ZEEF.com, a SaaS-based content curation and discovery platform combining human expertise with search technology. In 2017, ZEEF pivoted into influencer and performance marketing, forming the foundation for LinkPizza.com, where I served as Founder & CEO. At LinkPizza, I was responsible for vision, strategy, fundraising (€2M), team leadership (up to 13 FTE), and high-level product development, scaling the platform towards ~€1M in annual revenue before my role ended in 2025. Throughout my career, I have worked with perseverance, resilience, and a strong sense of ownership, leading multidisci
