Keuze.nl

Started 2007 · Keuze.nl brand 2020 · Advisor since 2024 · keuze.nl

Keuze.nl is a Dutch consumer comparison platform. It started in 2007 when a neighbour asked me whether he was paying too much for his internet. I worked at an internet provider at the time. My answer was: yes, and don't switch to us.

That became the operating principle: recommend only what I'd recommend my family. From the single internet-price check, the business grew into energy, internet, mobile, and insurance. At some point we were running thirty niche comparison sites side by side. In 2020 we closed most of them and moved everything under one brand, Keuze.nl. It was the biggest bet of the decade.

The business has helped around 192,000 Dutch households switch contracts and won the FD Gazellen award five consecutive years, 2018 through 2022. I led the company through the growth period and stepped into an advisory role in 2024. The team is now run by Melvin Paalvast and Geert Wirken; I am still close to the strategy calls.

Internet Ventures

Dutch online M&A · Private

The label under which I acquire and reposition Dutch internet companies. Some are consumer sites, some SMB tooling, some niche comparison platforms. The common thread is an operator who wants to hand the business on and a business that wants a second chapter.

If you are a Dutch founder thinking about what comes next, the third paragraph of your email should be numbers.
