1. Netcompany
Netcompany is one of the largest it companies in Copenhagen and a common choice for digital change in the public sector. Ministries, cities, and agencies use its systems for tax, case handling, and citizen services. Big private firms also work with Netcompany on core platforms.

For AI projects, Netcompany often sets the base systems while a partner like Tezeract builds AI-powered tools on top. This mix works well for leaders who want both long term stability and faster, focused change.
2. Trifork
Trifork is a product focused firm that many people link with new digital products in the city. It works on mobile apps, digital products, and low latency platforms in fields like finance, health, and logistics.
