Sjoerd really helped us connect with our potential customers. The Kopse Waard website is a great tool for presenting our plans and gathering feedback.

Always a quick response and a solution. With clear explanations about how you can adjust things yourself if you want, or to have them fixed if that's what you want.

Helen van Empel

Founder / Owner at Onesession

Having a website built by Sjoerd means you’ll hardly have to do any work yourself. He thinks along with you and goes the extra mile in his advice: coming up with solutions you hadn’t thought of yourself. Moreover, communication is direct, and you can count on quick service. In short, excellent value for your money!

We couldn’t be happier with our new, original website! Sjoerd came up with a design proposal and structure for our new website that we immediately liked. During the process he was always helpful and patient, had an eye for detail and often thought a few steps ahead.
