NextGO Epi develops and manufactures Gallium Oxide epitaxial wafers—the electrically active layer used in high-power semiconductor devices. The company, founded in 2025 as a spin-off of the Leibniz-Institut für Kristallzüchtung (IKZ), claims to be Europe’s only producer of industrial-quality Gallium Oxide epiwafers up to 4 inches. Its technology targets applications including EV charging stations, renewable energy inverters, AI data centres, and missile tracking systems. NextGO Epi reported it is already in production, generating revenue, and serving customers on three continents. The company highlights performance advantages of Gallium Oxide over silicon carbide and gallium nitride, and has brought on Dr. Jochen Linck as an Operating Partner to support commercial scale-up. The newly raised capital will be used to accelerate product development, grow the team, and expand commercial reach across Europe and global markets.

Einklang delivers an Energy-as-a-Service platform that bundles electricity procurement, on-site battery storage, intelligent control software and flexible tariffs into a single solution for small and medium-sized enterprises. Its technology automatically shifts consumption to periods of high renewable generation, mitigating price volatility, peak loads and grid fees without adding operational complexity for customers. Installation is typically completed within three months and the system is already deployed at several manufacturing and industrial sites. Backed by founders with experience in industrial energy systems and algorithmic energy trading, the company plans to deepen its technology stack and widen strategic partnerships. With the new capital, Einklang targets scaling to 100 customer sites by 2026. The Cologne-based startup positions itself as a cost-saving, autonomy-increasing alternative for businesses left out of large-industry energy relief schemes. Financially, it has just secured €2.2 million to fuel these growth ambitions.

Founded in late 2023 in Munich, nuuEnergy develops regional “hub” businesses that plan, install and service heat-pump systems, using proprietary digital tools and on-site system planners to streamline each project. The company targets the bottlenecks that slow Germany’s heat-pump adoption—skilled-labour shortages and fragmented installation workflows—by offering structured working conditions and modern software for its specialist teams. nuuEnergy earns revenue from installation projects, long-term maintenance contracts and ancillary offerings such as water-treatment systems and energy consulting. Positioning itself between small craft installers and purely digital platforms, the startup provides end-to-end local service while maintaining efficiency through digitised processes. The founders believe partnerships with cooperative banks can also enable tailored financing for customers’ heating transitions. Recent seed funding will be used to launch additional regional hubs and further automate planning and installation workflows.
