Decerno

What Decerno does

Decerno AB is a Swedish IT consulting firm founded in 1984 in Stockholm, wholly owned by Nasdaq Stockholm-listed Addnode Group, that specializes in bespoke (skräddarsydda) custom-built business systems for Swedish public-sector agencies and large enterprises. The company develops and operates mission-critical applications such as the Cåbra case management system for Åklagarmyndigheten (in development since 2003), Pastill for BUP Stockholm's child psychiatry services, InCheck for the Ledningskollen infrastructure registry, and ConCheck for digital concrete monitoring in construction, alongside broader custom business systems, GIS, route optimization (used by Hemglass and Skånetrafiken), low-code delivery (OutSystems), data management, and application security services.

The firm operates from offices in Stockholm, Gothenburg, Malmö, and Uppsala, plus a virtual office, and maintains ISO 27001 and FR2000 certifications and a Kammarkollegiet framework agreement that pre-qualify it for regulated public-sector work. Decerno has built a productized AI advisory practice around an AI Lab, AI Maturity Assessment Tool, AI Kickstart workshops, and a published 7-step AI Roadmap, with active capabilities spanning generative AI, retrieval-augmented generation, AI agents, predictive analytics, and AI-specific application security.

Revenue is generated through project-based professional services engagements with an enterprise field-sales model, typically beginning with low-cost feasibility studies (förstudie) and expanding into multi-year system development and maintenance contracts. Customer concentration is spread across roughly two dozen named government and enterprise logos, with a notable tilt toward Swedish public-sector agencies; long-term, multi-decade relationships (for example, Cåbra, Fastighetsbyrån's brokerage system handling roughly a quarter of Swedish property transactions) produce meaningful switching costs and a recurring revenue base.
