    2016 has shown us that stopping catastrophic climate change is not something that can be left to our politicians. As citizens and consumers we need to be a driving force for creating a sustainable society. The EU estimates that energy savings in residential homes can exceed those from any other action we can take as consumers. That is why we believe it is critical to give people control over their home energy consumption. Our product makes it easy to understand your energy use and helps you to make better decisions. Also, it’s a fun piece of technology to have and use.

    Our team consists of about 20 people working full-time out of an office in the heart of Stockholm. We collectively speak Persian, Japanese, German, French, Russian, Mandarin, Italian and a number of Swedish dialects.
