Martinsen focuses particularly on technology companies and companies with technology as their primary value proposition. He works with companies in all phases of their lifecycle, including startups, companies needing financing – both equity and loan capital – companies undergoing financial restructuring and all forms of exit and sales processes.

His experience of the various phases a company undergoes has also given him an in-depth understanding of the different aspects that must be taken into account in each one. In addition to M&A processes, Martinsen has helped clients with all kinds of IT services, from basic service and support to the procurement of advanced IT systems.

Knut Martinsen has a unique ability to solve problems and unlock situations where both parties are stuck.
