Eritreum is a small software- and technology advisory firm located in Oslo, Norway.

We grew up with computers and the Internet, which is now part of our blood. We have over 20 years of experience building world-class software-based products and services for some of the world’s leading technology companies such as Microsoft and Telenor.

We aim to understand the full picture, looking at the system and the required bits and pieces. We believe the winners of tomorrow are those who can integrate deep understanding of both technology and business into a complete strategy.
Keeping it real is important to us, and we spend sufficient time learning new technologies and understanding how these new technologies will evolve and provide business opportunities.


We provide advisory for organizations who want to leverage software- and technology to accelerate their business strategy. Perhaps you are building a professional software development organization, need to conduct a technical due dilligence, or need help to understand how to use analytics to support your decisions in real-time.

We can help creating an environment fostering creativity and innovation. Our approach is science-based, drawing upon insights from decades of research in computer science, psychology, organizational science, group dynamics, and innovation theory.
