Web development

Since we were founded in 2009, we have worked with large and small web applications. This includes open-source applications that we have expanded and built upon, as well as custom solutions that needed to meet a very specific need. We are competent in most modern web development technologies, which is why we take pride in choosing just the right technology for you!


We are a community of skilled web developers passionate about creating digital solutions that make a difference. We are not a typical consulting house – we are more like a team of creative problem solvers who love to work together with our clients to create the perfect website or web application.

What can we help with?

This is always one of the hardest questions for us to answer clearly. We believe that we can actually help with most things, technically at least.

We can bring a system to life, thereby giving you a competitive edge by either having a slightly cooler interface for your customers or maybe making things a bit smarter in administration.

Over many years, we have created countless different systems. Some have been straightforward and easy to explain, like a webshop for Humac, or an LMS system for CBS. But other times, we are lucky enough to deliver exactly the system that does not exist out there. It could be a competition system for pigeon racing or a temp management system for JKS.

We pride ourselves on our ability to tackle virtually any challenge. From revitalizing existing systems with new features to crafting entirely new platforms, we bring systems to life, offering our clients a competitive edge through superior interfaces and smarter administration solutions.
