About us
We make energy efficiency simple—for everyone
Gadder began with a simple observation: Norway is full of buildings that waste energy and people who want to do something about it. The problem is not a lack of motivation. It is a lack of tools that shorten the path from insight to action.

What we believe in
Saving energy should not require an engineering degree—and if you are an engineer, your tools should not waste your time. We build technology that removes friction at both ends: homeowners get a plan without doing the technical work, while advisors get a model without entering every room by hand.
Two products, same engine
Privat gives homeowners an automated energy upgrade plan with proposals from suppliers and banks. Proff gives energy consultants and building engineers AI-powered modeling and calculations connected to Enova's energy labeling system for larger buildings. Under the hood, both products share the same goal: greater energy savings with less friction.
Why it's urgent
Buildings account for a significant share of Norway's energy use. Meeting our climate targets requires a sharp increase in the pace of upgrades—and that will only happen if taking action becomes simpler, faster, and more cost-effective. That is the challenge we have set for ourselves.
