Hamburg's Rabot Energy raised a Series B reported at €50 million, led by Endeit Capital and DeepTech & Climate Fonds, to grow its home-battery virtual power plant.
What Happened
Rabot Energy, a Hamburg-based climate technology start-up, has raised a Series B round reported at €50 million to link household batteries into a "virtual power plant" that stores electricity when renewable power is plentiful and releases it when it is scarce. The round, announced around October 15, 2026, was led by Endeit Capital and Germany's DeepTech & Climate Fonds, with all of the company's earlier institutional backers taking part again, including HV Capital, High-Tech Gründerfonds and Bosch Ventures. Some English-language reports give the amount as $50 million. The valuation was not disclosed. Chief executive Jan Rabe's company says the money will help it reach one million customers and connect more home batteries, electric-car chargers and heat pumps.
Key Facts
- Amount: €50 million Series B (reported by some outlets as $50 million); valuation not disclosed.
- Lead investors: Endeit Capital and the DeepTech & Climate Fonds.
- Returning investors include HV Capital, High-Tech Gründerfonds, Bosch Ventures, CNI, Acurio Ventures and vent.io.
- Goal: one million customers, and more connected devices such as home batteries, EV chargers and heat pumps.
- Product: Rabot Flow, launched in June 2026, combines a dynamic electricity tariff, a smart meter and a plug-in home battery; it does not require rooftop solar panels and can be used in rented flats.
- Scale: more than 200,000 customers, up from about 35,000 in January 2024, according to reports; one report also cites 135 employees and €200 million in revenue.
Why It Matters
As more electricity comes from wind and solar, the supply of power rises and falls with the weather. On sunny, windy days there can be more power than the grid needs, and prices fall; on still evenings supply is tight and prices rise. Big batteries on the grid help balance this, but so can thousands of small batteries in homes, if they are coordinated. That is the idea behind a virtual power plant: software that treats many household devices as one large, flexible power station.
Rabot Energy's approach targets a group usually left out of the home-energy boom: people without their own roof. Home batteries are often paired with rooftop solar, which renters usually cannot install. A plug-in battery combined with a tariff whose price changes through the day lets these customers charge when power is cheap and use it when it is expensive, saving money while helping the grid.
The size of the round, and the fact that every earlier backer invested again, shows investor confidence in the model. If the model works in Germany, it offers a template for other countries adding large amounts of wind and solar power.
| Item | Detail |
|---|---|
| Round | Series B, about €50 million |
| Leads | Endeit Capital, DeepTech & Climate Fonds |
| Customers | More than 200,000 |
| Target | One million customers |
| Key product | Rabot Flow (tariff, smart meter, plug-in battery) |
Impact
Short-term: Rabot Energy can expand its services for homes and businesses in Germany and connect more devices to its platform. More customers will be able to use dynamic pricing with a plug-in battery.
Long-term: If it reaches its goal of one million customers, the company would control a sizeable pool of flexible storage, which could help grid operators balance supply and demand as renewable power grows.
Who is affected: German households, especially renters, looking to cut power bills; grid operators managing a power system with more renewables; investors in climate technology; and makers of batteries, chargers and heat pumps that connect to such platforms.
Key Takeaway
Hamburg's Rabot Energy has raised about €50 million to turn home batteries into a virtual power plant, aiming to grow from more than 200,000 to one million customers.
