Three things we do
Website design. A website with its own design in your brand, live within a week, at a fixed price of €995, €1,495 or €2,495 excl. VAT. No templates and no page builders.
Custom software and apps. Web applications with logins, dashboards, bookings, payments and client portals, apps for your customers or your team, and integrations with the systems you already use.
AI and automation. An AI phone assistant, a chatbot that books appointments, and automations for the work that always goes the same way. We use all of it ourselves.
How we work
It starts with a short check of your current site or your plans, free and without a sales pitch. In a call we agree on scope, price and delivery date. Then we build: you get a preview on a temporary address, and after your approval it goes live on your own domain.
Every website comes with our software, from €79 a month excl. VAT: hosting, domain, maintenance, updates and the workspace, one screen where bookings, reservations and enquiries from your site arrive straight away, next to your customers, quotes and reviews, on your computer and as an app on your phone.
Who we are
You talk to the people who build it. Twan van Hulst is the designer and does the build and the technology, Lorenzo Ruisi does the strategy. Nothing is outsourced. DesignCheck is based in Mijdrecht, the Netherlands, and works with businesses across the Netherlands and abroad, on site or remotely.
We measure quality instead of promising it. On 25 October 2026 the designcheck.nl homepage scored 98 for performance on desktop and 91 on mobile in Lighthouse, Google's measuring tool, 97 for accessibility and 100 for SEO and best practices. Every change is tested on phone and desktop before it goes live.
