The Energy Market is Broken. You Will Help Us Fix It.

Elvy was founded on a simple idea: homeowners shouldn't have to be engineers or millionaires to have a sustainable home. What Spotify did for music we do for energy, turning a complex, expensive ownership model into a seamless, worry-free subscription.

We install solar panels, a heat pump, and a battery system with zero investment required for the customer. The homeowner gets a fixed monthly price including all energy consumption and peace of mind for 15 years. 

We are in the midst of closing our Series A, recently secured significant debt financing to scale, and proven the model in Sweden. Now, we are entering an intense growth phase.

Working at
Elvy

Elvy is building the energy company that should have existed already. We design, finance, install, and operate distributed energy systems that cut costs, slash emissions, and actually work in the real world. No hype. No science projects. Just infrastructure that turns buildings into energy assets and makes clean power a clear economic win. We move fast, take ownership end to end, and obsess over execution. If you like solving hard, physical problems with real consequences and you want your work to matter at grid scale, you will feel at home here.
