DateStageInvestorsRaisedValuationDeal Summary
Oct 2026Undisclosed stageMarunouchi Innovation Partners (lead)$79M$1.4B1Komma5, the Hamburg-based home electrification company, raised EUR 70 million from existing and new investors in October 2026, at a valuation the company put at USD 1.35 billion, about EUR 1.2 billion. The Japanese clean technology fund Marunouchi Innovation Partners joined as a new investor, and the company expects it to contribute experience from energy investments in the United States. The funding was raised instead of a stock market listing, which the company has put on hold, and the company is also weighing a US market entry next year. The proceeds are meant mainly for its Heartbeat AI energy management software, in which it plans to invest more than EUR 100 million next year. Annualised software revenue reached about EUR 30 million, nearly double the previous year. 1Komma5 was founded in 2021 by Philipp Schroeder and Jannik Schall and sells solar systems, home batteries, heat pumps, air conditioners and wall boxes, linked by software that controls them and optimises energy flows. It reported revenue of close to EUR 520 million in 2024 and expects about EUR 700 million for 2026. It had raised around EUR 400 million in equity before this round.
Jul 2025Undisclosed stageSabanci Climate Ventures--Sabanci Climate Ventures became a shareholder in the German home electrification company 1KOMMA5° through an extension of the company's pre-IPO financing round, announced by 1KOMMA5° on 28 July 2025. The company said the extension brought Sabanci Climate Ventures on board as a new shareholder, alongside continued participation from existing investors including Hamilton Lane, CalSTRS, G2 Venture Partners, Porsche Ventures, Eurazeo, b2venture, eCapital, 2150, Norrsken and Blue Elephant Ventures, and the family offices of Haniel and Schürfeld together with Jan Klatten. The size of the extension and the amount invested by Sabanci Climate Ventures were not disclosed, and no valuation was published. The round being extended was a EUR 150 million pre-IPO financing that 1KOMMA5° announced on 20 December 2024, in which the California State Teachers' Retirement System was the largest new investor and G2 Venture Partners was a co-lead; that round took total equity raised by the company to close to EUR 400 million. 1KOMMA5° said the additional capital would support the scaling of its Heartbeat energy management software as it prepares for a stock market listing. The company was founded in Hamburg in 2021 and sells rooftop solar systems, batteries, heat pumps, electric vehicle chargers and green electricity tariffs to households, having built its installation network by acquiring regional installers. Its Heartbeat platform aggregates the installed systems into a virtual power plant controlling more than 500 megawatts. 1KOMMA5° reported revenue of around EUR 520 million in 2024, up from about EUR 450 million in 2023, employs roughly 2,500 people and operates around 80 locations across seven markets.

For fiscal year 2024, 1KOMMA5° reported preliminary revenues of approximately €520 million, representing 15.5% year-over-year growth from €450 million in 2023.

The company achieved this growth while maintaining profitability, with the company previously reporting operational profit (EBIT) of approximately €50 million.
