Next steps

Founded in Berlin, autarc is a ~40 person start-up who were part of Y Combinator's S24 batch in San Francisco. Our team consists of people in Sales, Tech and Operations, with the Engineering & Product department currently ~20 people, as we continue to grow throughout the year., Right now, 25% of CO2 emissions in Europe are caused by heating our buildings. In order for this to be reduced, the transition towards renewable energy needs to be simplified and made more accessible. There are too few installers to meet the growing demand for heat pumps, and a solution to match this trend needs to be brought to the market. autarc is developing the leading operating system (OS) for heat pump installers, enabling a more digital and efficient installation process for heat pumps. Through this, autarc is reducing the hurdles to decarbonizing single-family homes and small apartment buildings in Europe, with the goal to help with the planning and designing of 1 million heat pumps by 2030.
