Web Development

Web development for those with complex needs

Many companies find that their website is holding them back.

Maybe your technology is outdated, or your content is difficult to present clearly. Perhaps key system integrations are missing, or your website simply doesn’t meet your specific requirements. As a result, internal resources may be used inefficiently, visitors may leave, and your website may not achieve the goals you’ve set for it.

Get a professional website that fits your business

As a professional web agency, we know how frustrating it is when your website holds you back.

We combine your knowledge of your business and target audience with our web expertise and AI-assisted development process. That way, you don’t just get a website – you get a tailored web solution.

Good web development isn't just about technology; it's about helping you achieve your specific goals. Anything less is frankly a waste of everyone's time and effort.

Collaboration

Future-focused web development – in collaboration with you

We go all in to build websites that work for you for years to come. For us, web development is about collaboration and understanding. We work closely with you to understand your business and your users’ needs. Only then can we create a web solution with:

Real usability – for both editors and visitors
A strong brand identity – aligned with your overall visual identity
The right functionality – so you don’t have to squeeze triangles through square holes to present your content.

Our collaboration with Illumi is very much about how we can constantly improve the communication and user experience. Illumi knows us so well, and they are good at being critical, constructive and thinking more long-term, so we don't waste a lot of time developing something that doesn't provide enough value.

How to succeed with your new website

As your professional web agency, we're with you every step of the way, from initial consultation to finished website. With people and AI closely integrated throughout the process, we ensure every stage is thoroughly considered – and we mean it literally when we say we develop your website together with you.

Clarification: What will your website be used for?

Should your website inform or should it sell? Who is your target audience, what is your product and what role should your website play in the overall user journey and business strategy? We clarify these questions together with you.

Choosing a CMS

Which CMS is best for your business depends on the answers to the questions above, among other things. Our only priority is choosing the platform that best fits your needs.

Digital design (UX, UI & IA)

Your digital design needs to engage users both visually and functionally, guiding them towards the actions you want them to take. And its structure should be designed to support your content and key messages. Help us understand your business and your users. In return, we'll create a design and information architecture that supports your goals.

Web development

Our developers make sure your users have a frictionless experience when they visit your website. We also create a simple and intuitive editor universe. All you have to do is provide feedback along the way.

Test

Together with you, we continuously test in a dedicated test environment as we develop new functionality for your website. This helps us ensure that your website launches as smoothly as possible.

Performance and technical SEO/GEO

SEO and GEO (also known as AI SEO) involve far more than producing credible content. We focus on page speed, semantic structure, schema markup (structured data), and all the other technical foundations that search engines and AI crawlers reward.

Handover and training

When your editors are ready to take over, we provide a training day with you. Here, they get to know the CMS in depth so they can confidently manage and populate your new website with great content. We’re also happy to share guidance on writing effective content, including how AI can support the process.

Operations, hosting, maintenance and support

Once your website has launched, your dedicated Illumi team is ready in the background to support you whenever you need it. Ongoing operations, hosting, support, and further development ensure your website continues to perform and deliver value for years to come.
