Senior🎓
Top SchoolHarald Lønsethagen is a founder and CTO with a decade of hands-on software experience building product-led engineering teams and mission-driven startups from Oslo. He co-founded Revolve NTNU Driverless to build the Nordics' first autonomous race car, later launching VC-backed Shepherd and now Perlo, blending deep technical delivery with product and operations leadership. His background spans full-stack web and data science—shipping .NET, React, Python ML models, and scalable SaaS—alongside certifications as an Azure Developer.

That combination of competitive robotics, consulting experience, and startup execution gives him an uncommon knack for turning complex systems into pragmatic products.
