We build online experiences for impactful brands

Are we a match?

Our vision

Ever since 2017, Vallonic has been developing itself as a leading partner in the Dutch web development space, serving agencies, as well as semi-government and medium to large enterprises directly.

One of our core strengths is our stance on brands. We only code for highly motivated branding agencies and organizations that are all-in on branding — and therefore have high quality building blocks for us to work with.

Regardless of whether we're building in Craft, Laravel, WordPress, Webflow, or a combination of platforms, the final product is backed by our communications-heavy process and, most importantly, the art direction and concepts of the envisioning branding teams.

We value efficiency, a systematic approach to working and organizational learning. The leading product resulting from these values is our own in-house developed WordPress Framework, which seamlessly integrates a Webflow front-end onto WordPress.

Regardless of the platform we choose, the end result is a manageable, enterprise-ready, engaging and secure website.

...exactly what you dreamt of.
