What's the endgame? The company wants to turn individual households into a connected energy network. It pools home battery storage into a virtual power plant, charging when renewable electricity is abundant and discharging when it is scarce. Every kilowatt-hour shifted this way cuts the need for gas-fired generation at peak hours.
By the numbers: In three and a half years, Rabot has acquired more than 200,000 customers — including about 15,000 business and industrial accounts — and grown turnover to €200 million. It supplies over 600 million kilowatt-hours of green electricity, and says customers saved a combined €45 million by 2025 against standard supplier prices.
What's the money for? The capital funds the next growth phase: reaching one million customers, expanding its offering for residential, commercial, and industrial clients in Germany, and connecting more devices — from batteries to EV chargers and heat pumps.
Why now? As transport and heating electrify, electricity demand is set to grow 2.5 times faster than overall energy demand by 2030. That makes when and how power is consumed as important as how much is generated.
Context: The round sits in the top 12% of Series B deals for energy startups in Germany by size, based on 68 comparable rounds.
The signal: "The next generation of power plants will not be built; it will be connected," said chief executive officer Jan Rabe. As Germany's grid leans harder on renewables, flexibility — not just generation — is becoming the scarce resource, and investors are backing the firms that can aggregate it.
