Arkitektum

What Arkitektum does

Arkitektum AS is a Bø i Telemark-based Norwegian IT consulting and software development firm founded in 2008 by Tor Kjetil Nilsen, specializing in digitization of the Norwegian public sector across four tightly-defined domains: planning, building, geodata and archives. The firm designs and operates core national components on behalf of Norwegian directorates, including Fellestjenester BYGG (the common digital building-application service running on the Altinn platform and distributing to all Norwegian municipalities via KS SvarUt) and Fellestjenester Plan (digital planning-process pilots). It has developed and maintained Geonorge.no for Kartverket (Norwegian Mapping Authority) since 2013 under the Norge Digitalt framework, and delivers archive-transfer testing via Arkade 5 for Arkivverket, plus Enterprise Architect / QGIS plugins (SOSI UML-to-GML, GISTools for UML, GeoStyle Assistent) used by Norwegian GIS professionals. Its technology stack spans C#, Java, PHP, JavaScript/React/Vue, .NET, Azure, AWS and ElasticSearch, with model-driven tooling around SOSI, GML and NOARK5 standards. The revenue model is primarily professional services — bespoke consulting, system development, system architecture, information modeling, GDPR/privacy advisory and project management — supplemented by a small licensing/royalty stream from QGIS plugins distributed via public repositories and direct enterprise licensing of model-driven tools. Customers are concentrated in Norwegian central government: DiBK, Kartverket, KS, Arbeidstilsynet, Arkivverket, Brønnøysundregistrene and indirectly all Norwegian municipalities through the Fellestjenester BYGG ecosystem. In 2024 Arkitektum began layering AI onto its consulting base — most notably Planslurpen (generative AI structuring of regulatory plans) and KI Begrepsassistent (Azure OpenAI + RAG for ESG reporting, piloted with Brønnøysundregistrene) — and was awarded Årets IT-fyrlykt i offentlig sektor at NOKIOS 2024 alongside Business of the Year in Midt-Telemark.
