The Agency

Conlumina is a full-service WordPress agency in Stockholm and Berlin, with a strong focus on usability, aesthetics, and performance.

Its founder and principal developer, Fabian Kastner, works directly with all clients and is responsible for the overall quality of each project. A web and software developer with over 20 years of experience, a contributor to the WordPress core, and a well-rounded expert in all of the services that Conlumina offers, he is committed to ensure the highest level of service is delivered.

Fabian works with a team of developers, UX/UI designers, SEO specialists, copywriters, and creatives based on the specific needs of the project. The result is an agile team that works efficiently, collaborate effectively, and has the necessary expertise to provide confident guidance throughout the project.

Our Expertise
Usability

At the end of the day, it's all about the user experience of the individual user – including people with disabilities.

Aesthetics

Our digital interfaces are clean, intuitive, functional, and consistent. Mindful, with a high attention to detail.

Performance

We take pride in our code. Every function and component that we deliver is built with performance at the core.

What Clients Say
Not only did we get a great user experience for our customers. Thanks to the methodical approach of research, validation, planning, and design, we also reached our business goals.
Guy Saban, Online Marketing Manager at Tuttnauer
Smooth cooperation on design and development of our new website. Nice to work with a developer that easily understood our needs and requests, and efficiently turned them into solutions. A small agency that you can rely on.

I highly recommend Conlumina for their WooCommerce expertise to anyone facing the common challenges of establishing an e-commerce business.
Lior Ashkenazi, Chief of Staff at ehouse
Fabian is a pleasure to work with, filled with good will and a positive vibe, always giving us a safe feeling that he knows what he's doing. We are thankful from the bottom of our hearts to have met him and for having him with us on board.
Adi Levy, Product Manager at Artist-Run Alliance
Finally, we have a website we no longer have to feel ashamed about. The site looks great and works even better than we had hoped for – we're so proud of the end result.
Niklas Haga, Editor in Chief, Aiolos
We had a very specific vision of what our website should look and feel like. Conlumina really went out of their way to realise it in every little detail, and then some. The design is simply perfect. We couldn’t be happier with the result!
