1KOMMA5°
1KOMMA5° (named for the 1.5°C climate target) is one of Europe’s fastest-scaling energy transition companies, reaching unicorn status in roughly 21 months. Based in Hamburg, the firm tackles the “last mile” of decarbonization by combining a roll-up acquisition strategy with a software-defined energy platform. Instead of only selling solar panels, 1KOMMA5° acquires local installer businesses across Europe and digitizes them to deliver end-to-end home electrification — solar, batteries, heat pumps, and EV chargers — with consistent quality and financing. The company’s differentiator is Heartbeat, a proprietary energy management system that turns these assets into a virtual power plant. Heartbeat orchestrates when batteries charge or discharge based on real-time spot prices and grid conditions, allowing households to capture savings from dynamic tariffs and to export power during peak demand. In 2025, the system expanded to automated trading of household energy, making “free” electricity periods during windy or sunny hours a tangible consumer benefit. This blending of hardware deployment and energy-software automation allows 1KOMMA5° to capture margin both on installation and on recurring software and energy services. Founder Philipp Schroder (former Tesla country director and Sonnen executive) used his industry network to skip early accelerators, and the company instead embedded itself in the Hamburg Startup City ecosystem. Its acquisition engine is relentless: by buying regional market leaders, it locks in the most scarce resource in the sector — skilled installers — while rapidly expanding geographic reach. By early 2026, 1KOMMA5° had expanded beyond DACH into the Nordics, Spain, and Australia, positioning itself for a cross-continental footprint ahead of a public listing. The company has signaled an IPO-readiness push, backed by record turnover reported for 2024 and an expansion into branded hardware components to increase margin and supply-chain resilience. Its investor base blends strategic and growth capital: Porsche Ventures provided early backing, G2VP brought Silicon Valley cleantech expertise, Eurazeo and eCapital added European growth capital, and Norrsken VC underscored the impact thesis. In 2026, 1KOMMA5° is a case study in how Europe can scale climate tech through operational execution rather than pure technology — a disciplined roll-up with a software heart that turns millions of households into coordinated energy assets.
