Overview
1Komma5° (pronounced "one point five degrees") sells and installs home energy systems: rooftop solar panels, home batteries, heat pumps and electric vehicle chargers. Its name refers to the Paris Agreement goal of limiting global warming to 1.5 degrees Celsius. What sets it apart from a traditional installer is software: its Heartbeat AI energy manager connects a household's devices, buys electricity when prices are low, stores it, and sells or uses it when prices are high, reducing customers' bills. 1Komma5° has grown rapidly by acquiring and integrating established local installation businesses across Germany and other European countries.
The company was founded in Hamburg in 2021 by Philipp Schröder, a former head of Tesla's German business, together with a small group of co-founders. In October 2026 it raised €70 million in a round led by b2venture at a pre-money valuation of US$1.35 billion, according to Tech Funding News. It had prepared for a Nasdaq listing, but the IPO was postponed, according to reports, as it focused on profitability and US expansion.
Products and services
- Solar installations: rooftop panels designed, sold and installed by its network of local businesses.
- Home batteries: storage that lets households use solar power in the evening and shift grid purchases to cheap hours.
- Heat pumps: electric heating systems replacing gas and oil boilers.
- EV chargers: home charging integrated with solar and dynamic tariffs.
- Heartbeat AI: software that optimises when devices consume, store or export electricity based on prices and forecasts.
- Dynamic electricity tariff: a power supply contract tied to wholesale prices, which Heartbeat uses to cut costs.
Funding
1Komma5° raised significant venture capital from its launch, with investors including Porsche Ventures and Eurazeo, and became a unicorn within a few years. Its October 2026 round of €70 million was led by b2venture at a pre-money valuation of US$1.35 billion, as reported by Tech Funding News and Sifted. Sifted reported that IPO plans remained on hold. The company said it would use the money for growth, including in the US, and for AI development.
Business model
1Komma5° earns revenue from selling and installing energy hardware, which typically involves large one-off payments of several thousand to tens of thousands of euros per household, often financed. It adds recurring revenue through its dynamic electricity tariff and Heartbeat subscriptions, and potentially through aggregating many home batteries into a "virtual power plant" that sells flexibility to grid operators. The recurring software and energy revenue is key to its valuation, because installation businesses alone typically trade at modest multiples.
Competition
1Komma5° competes with Enpal, another German home solar company, and with thousands of local installers, energy utilities offering solar and heat pump packages, and companies such as Octopus Energy, whose Kraken software also optimises home devices. In the US, it would compete with Tesla, Sunrun and Base Power. Its advantages are its software platform and its acquisition-driven network of experienced installers.

How Heartbeat AI saves money
Electricity prices in Europe vary widely during the day, often falling to very low or even negative levels when solar and wind production is high, and rising in the evening. A household with solar panels, a battery, a heat pump and an electric car can save significant amounts by timing its consumption. Heartbeat forecasts solar production, household demand and wholesale prices, then decides when to charge the battery, run the heat pump, charge the car or export power. Customers get lower bills without needing to manage anything themselves. Aggregated across many homes, these systems can also help balance the grid, which grid operators are increasingly willing to pay for.
The roll-up strategy
Installing solar panels and heat pumps requires skilled electricians and plumbers, who are in short supply across Europe. Rather than hiring and training teams from scratch, 1Komma5° acquires established local installers, keeps their staff and local relationships, and provides them with centralised sales, procurement, software and financing. This "buy and build" approach allowed rapid expansion but carries integration risks, as acquired businesses must adopt common systems while maintaining quality.
Market conditions
Demand for home solar and heat pumps in Germany surged in 2022 and 2023 after energy prices spiked following Russia's invasion of Ukraine, then cooled as prices fell and government subsidies changed. Heat pump sales in Germany fell sharply in 2024 amid political debate over heating rules. Installers that had expanded aggressively faced lower volumes. Companies with recurring revenue and software were better placed to weather the slowdown. 1Komma5°'s emphasis on Heartbeat and dynamic tariffs reflects this.
Who funds 1Komma5°
1Komma5°'s investors include b2venture, which led its October 2026 round, along with Porsche Ventures and Eurazeo.
