HAMBURG, Germany, German energy technology startup 1Komma5Grad has reached a valuation of approximately $1.35 billion in its latest financing round as it increases investment in artificial intelligence software designed to manage household energy systems.
The company announced the valuation on October 12, 2026, as it prepares to expand its energy management platform, Heartbeat AI. It plans to invest more than €100 million in the technology during 2027 and is considering entering the US market next year.
The development highlights how startups focused on renewable energy and home electrification are increasingly using software to manage electricity consumption, distributed energy resources and changing power prices.
AI Moves Into Household Energy Management
1Komma5Grad helps households transition toward electrified energy systems, including solar installations, battery storage, heat pumps and electric vehicle charging.
Its Heartbeat AI platform is designed to coordinate these connected devices, helping households use energy more efficiently and respond to changes in electricity prices and availability.
Rather than treating each device as a separate system, integrated energy management software can coordinate when batteries charge, when vehicles draw power and when stored electricity is used. The aim is to reduce energy costs and improve the efficiency of household energy consumption.
Such systems could become increasingly valuable as renewable generation grows and electricity supply fluctuates with weather conditions and demand.
Investment Targets a Larger Energy AI Business
The planned investment of more than €100 million in Heartbeat AI during 2027 signals the company’s intention to make software a more important part of its business.
The opportunity extends beyond individual households. Aggregating many connected energy systems could allow a platform to coordinate demand and distributed storage at a larger scale, subject to local regulations, technical capabilities and customer participation.
However, the commercial model depends on more than installing hardware. The company must demonstrate that its software can deliver measurable savings, operate reliably and integrate with different energy devices and electricity markets.
Energy prices, grid regulations and the availability of flexible electricity tariffs can vary considerably between countries, making international expansion operationally complex.
US Expansion and IPO Plans
Chief Executive Philipp Schroeder told Reuters that the company was considering entering the US market in 2027, citing interest from investors and the potential opportunity.
The company had previously shelved plans for a US initial public offering in 2025 amid uncertainty surrounding renewable energy and trade policies. Schroeder indicated that its performance in 2027 would be important in determining when and whether to pursue a listing.
1Komma5Grad has set a target of approximately $750 million in revenue for the 2026 financial year. Achieving that target while funding further technology development will be important for investors assessing its growth strategy.
Challenges for Energy Technology Startups
Energy startups operate in a market shaped by hardware costs, financing conditions, installation capacity and government policy. AI software may improve efficiency, but companies still need reliable physical infrastructure and customer adoption to translate technical capabilities into recurring revenue.
International growth also requires partnerships with installers, utilities and energy providers, alongside compliance with local electricity market rules.
For 1Komma5Grad, the next phase will test whether investment in energy software can strengthen its business beyond equipment installation and support a scalable technology model.
The company’s valuation reflects investor interest in the intersection of AI and energy transition. Its long-term prospects will depend on converting that interest into sustained revenue, customer savings and profitable expansion.
