About Hemma
At Hemma we are building technology that accelerates the transition to a sustainable, energy efficient future. The problem we are addressing is a corner stone in the climate transition. 40% of CO2 emissions are generated through properties and detached homes represent a large share of energy usage but is underserved due to complexity.
Hemma’s role is to support B2C companies to help their customers to reduce their energy consumption. Our core product is aggregation, processing, and analysis of energy data for detached houses. We also provide tailor-made advisory solutions on how to increase energy efficiency in private homes based on property specific data.
As of today tens of thousands of homeowners are supported via our platform that is used by some of the largest companies in Sweden in Finance and Energy. We are a small team, but we believe that everyone is entitled to a sustainable home and that we can make a difference!
What we believe in:
Being simple and straightforward: we stay pragmatic and cautious with time and attention. That should be obvious in the design of our products and how we interact with our stakeholders.
Caring about people: those here today and those belonging to future generations.
Innovation: iterating every day to find new and improved ways to catalyse this transition. We shall always stay curious and driven by facts and evidence.
Empowerment of people: homeowners, clients, colleagues. Internally at Hemma it is key to give and take responsibility.
