Hallvard Olaisen

CTO · Software Engineer · Architect

Experienced technology executive with deep expertise in AI, cloud, security, and software engineering.

I hold a Master of Science (MSc) in Computer Science from UiT – The Arctic University of Norway.

I am a technologist and product leader with more than 35 years of experience across cloud, AI, security and scale-up operations — from hands-on coding to board-level technology strategy. What truly defines me is my drive to keep evolving: building better systems, learning faster, and exploring technologies that expand what is possible.

Few shifts have been as transformative as AI. In recent years I have led the adoption of AI agents in software development, introduced AI-powered onboarding and contract analysis features, and implemented frameworks for human-in-the-loop validation and compliance reporting.

Throughout my career I have held roles as COO in a high-growth scale-up, CISO establishing information security governance from the ground up, and CTO modernizing large monolithic platforms into cloud-native architectures. I remain deeply technical and pragmatic, focused on delivering real value — fast, securely, and with purpose.

I have worked in both public and private sectors and with organizations such as Signicat, DNB/Vital and Accenture. Today I serve as CTO at House of Control, part of the Visma Group.
