1KOMMA5° operates Heartbeat AI, a virtual power plant that buys electricity on the spot market when prices (and CO2 emissions) are low and sells excess power back to the grid when prices are high. The company charges a flat software fee rather than margins on electricity and enables real-time individual electricity prices instead of conventional fixed tariffs. It positions Heartbeat AI as a grid-stabilizing solution amid rising renewable generation. Less than four years after its foundation, 1KOMMA5° has expanded through several acquisitions, including Arkana Energy, Solaray Energy, ZEWO Energy and Zonduurzaam. The company has secured a €150M Pre-IPO round, bringing total funding to over €650M. With the new funding it plans to accelerate growth, roll out Heartbeat AI across Europe and Australia, allow customers to become shareholders, and pursue an eventual IPO while building a European “New Energy” household brand. 1KOMMA5° develops a vertically integrated service platform for clean energy deployment, aiming to serve millions and replace fossil fuels and high energy costs. The company says it is executing toward a long-term 2030 trajectory and plans to become subsidy independent. Management is preparing for a public listing and has announced new U.S. investors joining as shareholders. The LinkedIn post cites Hamilton Lane and one of the largest U.S. pension funds as new shareholders and highlights continued interest from tier‑1 U.S. investors. Customer comments in the thread reference live installations (battery and wallbox) that have fed power into the grid and plans to use smart meters and Dynamic Pulse. Management thanks teams, partners, and customers and frames the investor additions as part of scaling the business internationally. 1KOMMA5° offers a one-stop shop for sale, installation and services for solar panels, energy storage, EV charging infrastructure and heat pumps, supported by its Heartbeat energy IoT platform. Heartbeat delivers centralized intelligent energy management to help homeowners optimize power consumption and increase grid independence. The company is pursuing aggressive European expansion through acquisitions and investments in portfolio companies in photovoltaics, charging infrastructure and heat pumps. 1KOMMA5° operates 68 locations with around 1,700 employees across Germany, Sweden, Finland, Denmark, Italy, Spain and Australia. It publicly targets €500M in revenues in 2023 and aims for €10B by 2030, planning to convert 1.5M buildings by then and to build capacity to convert 500,000 buildings per year. 1KOMMA5° provides carbon-neutral energy systems and the proprietary "Heartbeat" energy IoT platform that delivers centralized intelligent energy management to optimize home energy in response to price fluctuations. It operates a virtual power plant that pools customers' photovoltaics, electricity storage, heat pumps and charging columns to increase the profitability of networked customer systems. The company also invests in electrical-sector companies—focusing on photovoltaic systems, charging infrastructure and heat pumps—and offers partner entrepreneurs its software, centralized services, bundled purchasing, growth capital and a reverse shareholding in 1KOMMA5° Holding. 1KOMMA5° currently operates over 65 sites with around 1,500 employees across Germany, Sweden, Finland, Italy, Denmark, Spain and Australia and has capacity to convert 500,000 buildings per year to climate-neutral power, heat and mobility. Financially, the company became a unicorn in June after previously raising €630 million and this week closed an undisclosed double-digit million euro deal with VC firm 2150. It will use the funding to further develop and expand Heartbeat software and to open an R&D centre in Berlin with over 100 employees for software and product development and a test laboratory. 1KOMMA5° develops home-focused sustainable energy solutions, centered on its Heartbeat energy manager and companion app that give real-time visibility and optimisation of household energy flows. The company is pursuing vertical integration across the value chain and investing in device connectivity, virtual power plants, and broader energy management technology. It has expanded geographically via the acquisition of Viasol and operates with regional partners across 40 locations in Germany, Sweden, Finland and Australia, with further market entries planned. 1KOMMA5° announced a high double‑digit million investment in a new R&D site and team in Berlin to accelerate product and IoT development. Heartbeat is slated to be compatible with existing energy devices by 2024, supporting the company’s ambition to create the largest virtual power plant. The firm emphasizes reduced carbon footprints and energy cost savings for homeowners as core customer benefits.
