About Frequenz

Frequenz is a vibrant technology company developing groundbreaking artificial intelligence solutions that enable the rapid transition towards a decentralized world of energy. Our open source developer platform allows customers to accelerate their path towards 100% renewable energy. We’re helping companies rapidly transition from being passive electricity consumers to becoming fully self-sustaining prosumers, capable of leveraging various renewable energy assets. We empower them to take matters into their own hands as they pursue a better future for us all.

We’re passionate about making the impossible possible by rethinking out-dated processes and questioning the status quo, while turning the electric grid upside down. For us, the edge is the future, and our journey has only just begun. We’re looking for people ready to dive in head first, but be warned: it will be a hardcore ride where each day everyone tells you what we aim to achieve isn't possible. If this challenge doesn’t deter you, then you may be a good fit… after all, saving the planet is no easy feat!

Together with our clients, partners, early adopters, and innovators, we’re developing a global, leading-edge, open source, AI electricity platform. Join us - the planet needs your help!
