Naturally we work for our 144 clients. In addition, we have intensive contact with organizations that, like us, know the construction sector inside and out, and we contribute to collaboration and digitalization.

Since our foundation, we have been involved in various organizations in construction and IT. Acceleration and digitization of construction requires cooperation. That is why we consciously look for partners who complement us.


The Ketenstandaard Foundation (Dutch for Chain Standards) maintains various standards for construction. STABU2 and NL/SfB are important to Utopis Specifications and our clients use ETIM and DICO to classify and distribute product data. Our roots lie in the development of STABU and so the contacts between both organizations can be called warm.


Many of Utopis’ clients have a RAW specification service. RAW is maintained by the C.R.O.W., the knowledge institute for ground, road and hydraulic engineering in The Netherlands.


Together with CSN Group, part of Interstellar, we ensure that Utopis remains up and running. Our data and that of our 144 clients are safe in the data centers of Interxion (Amsterdam) and Previder (Twente). Both CSN Group and Interxion are ISO 27001 and ISO 22301 certified.


Together with Ketenstandaard and KOMO we maintain the search portal The online portal, formerly known as, is successful in distributing construction specifications. The index contains references to product specifications, system solutions, specification texts and certificates from almost all suppliers in the construction industry.

Branch organisations

Utopis is a member of the BNB, the Professional Association for Dutch Building Specification Experts, and FBS, an interest group for manufacturers of building materials. We helped set up both associations and we are still closely involved.

I am always determined to find a solution. This can be achieved by sparring together.

Zsolt Kiss

Zsolt is from Hungary and has lived in the Netherlands since 2016 and has been working at ZeeBoer since early 2023. Read below how you like it.

Just before the pandemic, Zsolt started studying Computer Science at the University of Debrecen. A broad study in which he learned both frontend and backend. He eventually specialized as a backend developer. And started looking for an employer in the area between Apeldoorn and Zwolle. He found the vacancy at ZeeBoer via LinkedIn. “When looking for a new job, I preferred a small organization, because I was looking for a position where I could learn many different technologies. Where I am not doing the same thing all day long, but have a lot of variety.”

After an initial conversation with Peter and Antoon, he had another technical conversation with Bernd. He could then get to work straight away. The first month was immediately challenging. Zsolt received a problem from Bernd to work on. “I am always determined to find a solution. By sparring together I succeed. I immediately learned a lot from it.”

Ultimately, Zsolt is happy with the choice to work at ZeeBoer. “It is exactly as I expected it in advance. The tasks vary. This allows me to gain knowledge about different technologies, such as JavaScript, C# and SQL. I also enjoy working in the team. They are friendly, and I feel accepted and welcome.”
