The story
The story behind DYKZ.

Nice to meet you, I'm Marnix Zandijk and I founded DYKZ. Over the past 20 years, I worked in-house as a MarCom specialist for a range of companies and clients. For large insurers, intermediaries and wholesalers, but also for start-ups and smaller businesses.
When it came to websites, I kept seeing the same pattern. A beautiful website was delivered, but a few months later it got stuck on an outdated plugin, a broken update or a theme that suddenly stopped working as it should. Or, over time, new wishes came up. For example, to expand, adjust the design or add extra features. The marketer or business owner then had to call in help again. Often at extra cost or with a long lead time.
That annoyed me. Not because CMS systems are bad, but because they are often used for business owners who have no need at all for all those extra layers of technology, updates and self-management.
Most business owners simply don't have the time or the inclination to work on their website after a day's work, do they? They just want a reliable website that performs well. Fast, stable, without hassle or extra costs.
That became the reason for DYKZ. In 2024, I founded DYKZ to build professional websites the way they should be built. Without unnecessary technology, without vulnerabilities and without maintenance bills. Just craftsmanship that keeps working for years, without you having to look after it if you don't want to.
I do keep an eye on it, by the way. Twice a year, I get in touch, with no obligation, to discuss any new developments, opportunities or wishes.

Principles
What DYKZ stands for.
Speed
A website that loads slowly loses visitors and revenue. Every website I deliver scores at least 95+ and often the maximum 100/100 in Google PageSpeed Insights.
Simplicity
No unnecessary technology, no superfluous features. A website doesn't have to be complicated to work well. Often, the opposite is true.
Personal contact
You call, message or email me, not an account manager or a ticket system. From the first conversation to years after launch.
Honest advice
If a custom build isn't the best fit for your situation right now, I'll simply tell you. Better honest advice than a sales pitch.
Craftsmanship
Why I build websites "differently".
I build differently because I can. Many web builders can adapt a CMS or a template and choose that convenience. I write W3C-valid HTML. My philosophy is simple. Build a website as light and clean as possible. Neatly structured and following the W3C guidelines, so that the website keeps working even after years.
No CMS
No system around it that constantly needs updating to stay secure, and no paying every month to keep everything running. My clients choose reliability and convenience, without extra costs or obligations. Be honest: as a business owner, do you really want to maintain your own website and pay a new bill every month?
No plugins
No separate bits of code built by third parties that can clash with each other or become outdated.
No templates
Every website is custom built to your wishes, specifically for your business. No template that looks a bit the same everywhere.
Valid HTML
Professional quality. Written line by line according to the official W3C web standards. That is the foundation for accessibility, findability and stability.
High Google PageSpeed
No unnecessary code or scripts, but fully focused on speed and ease of use. At least 95+ and top scores of up to 100/100 in Google PageSpeed Insights.
Easy to find in Google and AI
Thanks to a rock-solid combination of technical and on-site SEO, DYKZ websites are indexed very well. Not standard or basic SEO, but maximum optimisation. You are highly visible online in AI Overviews and search results.
Maintenance-free
No updates that may cause yet another problem, and no monthly management fees. Your website keeps running stably for years, with a guarantee of at least 36 months.
No obligations or subscriptions
Your website and all the code are yours. You can choose your own hosting and do whatever you like with your website. No mandatory subscription, hosting or maintenance.
