1KOMMA5° expands financing round

The Hamburg-based company 1KOMMA5°, which specializes in the electrification of private households, has once again expanded the financing round it closed in December 2024. Sabanci Climate Ventures, the climate investment arm of the Turkish Sabanci Group, is a new investor. The original round amounted to 150 million euros. It is not known exactly how much Sabanci has contributed.

The company intends to use the new capital to drive forward the further development and scaling of its Heartbeat AI platform in particular. This is an AI solution for energy management in private households.

Clean electricity directly from the exchange

With Heartbeat AI, 1KOMMA5° is pursuing the goal of replacing conventional energy suppliers. The platform connects photovoltaic systems, battery storage systems, heat pumps and wallboxes and controls them so that consumers automatically receive the cheapest and cleanest electricity. This is to come directly from the electricity exchange.

The system already controls more than 500 megawatts of flexibility capacity. According to the company, this makes it the largest virtual power plant for households in Europe. Over the next two years, more than 100 million euros are to be invested in the further expansion of this digital infrastructure.

Growth despite difficult market conditions

Despite declining demand in the solar and heat pump market across Europe and economic headwinds in Germany, 1KOMMA5° says it remains profitable. The company was not only able to increase its sales, but also invested heavily in the development of its software business.

It is precisely now that we can position ourselves as the long-term market leader. With Heartbeat AI, our vision is to develop the last energy solution that households will ever need.

With the participation of Sabanci Climate Ventures, the group of renowned investors continues to grow. Previous investors include Hamilton Lane, CalSTRS, Porsche Ventures, G2VP, Eurazeo, b2venture, Norrsken, as well as family offices such as Haniel, Schürfeld and Jan Klatten.

To date, 1KOMMA5° has raised a total of almost 400 million euros in equity capital without any significant external financing. The company currently employs around 2,500 people and serves over 120,000 customers in Europe and Australia.

Scaling software, securing market leadership

With the increased capital and the tailwind of the new partnership, 1KOMMA5° plans to rapidly expand the Heartbeat AI platform and tap into new markets. The aim is to establish itself as a leading provider of digital energy solutions in the European home market and thus drive the transition to clean, decentralized energy supply in the long term.
