What 1Komma5° does
1Komma5° (1KOMMA5° GmbH) is a Hamburg-based CleanTech company founded in 2021 by ex-Tesla manager Philipp Schröder, CFO Micha Grüber, and co-founders Jannik Schall, Philip Liesenfeld, and Sascha Koppe. The company sells and installs integrated residential energy systems — rooftop solar (Full Black TOPCon modules, including R-290 / TopCon variants manufactured with Wacker polysilicon), modular lithium-iron-phosphate battery storage (Heartbeat Battery), heat pumps (including Daikin units), EV wallboxes, hybrid inverters, and air conditioning — directly to homeowners across seven countries (Germany, Sweden, Finland, Denmark, the Netherlands, Spain, and Australia), with 3,000+ employees, 75+ German locations, and 80+ regional Meisterbetriebe (master craftsman operations) handling installation and service.
The company's technology core is Heartbeat AI, a proprietary energy-management platform that orchestrates solar generation, battery charge/discharge, heat-pump and EV-charging loads, and dynamic electricity tariffs (Dynamic Pulse, priced from 0 ct/kWh in low-price windows) for ~300,000 connected systems, and aggregates them into a residential Virtual Power Plant that has reached 1 GW of flexible capacity (500 MW connected) and delivers FCR-D frequency-control services in Sweden. ~200 developers at the Berlin TechLab build and train the platform, which integrates with the European wholesale Day-Ahead and Intraday markets, smart-meter gateways, and partner hardware (Tesla Powerwall 3, Sungrow, Enphase).
Revenue is generated across multiple streams: one-time hardware sales and turnkey installation (the largest, dominant stream at EUR 520 million FY2024 revenue), recurring software/SaaS subscriptions via Heartbeat AI and Dynamic Pulse, customer financing (EUR 1bn facility at 5.99% interest, up to 12-year terms) and grid-services / VPP wholesale revenues. B2C residential is the primary segment, with adjacent B2B (industrial customers such as Galfer in Spain) and public-sector (560 state-owned buildings in Lower Saxony, EUR 500m facility) expansion. Distribution combines a self-serve direct website (1komma5.com) with a dense physical installer footprint, supported by KfW subsidy processing, country-specific financing partners (Cetelem, BBVA, Sabadell Consumer in Spain), and in-house lead generation.
