Skeleton Technologies, a Tallinn-based developer of high-power AI infrastructure systems, has announced a significant investment of €9 billion from Siemens. This financing will bolster Skeleton's valuation to over €899 million ($1 billion) and accelerate its expansion of US manufacturing operations and R&D activities in Silicon Valley to meet the surging demand from hyperscalers for AI data-center power systems.
The company's innovative Curved Graphene material, combined with power electronics and system-level controls, makes AI data centers up to 40% more energy efficient. The investment comes amid a wave of European funding rounds for AI data center infrastructure and energy demands in 2026, including €107.6 million raised by Spain's iPronics for energy-efficient optical networking and €43 million for London's Orbital Industries to develop AI-designed data-center infrastructure.
Skeleton's Curved Graphene technology and power systems remove power fluctuations as a constraint, enabling hyperscalers to achieve higher performance from their GPUs with up to 40% energy savings. The US expansion plans include establishing domestic cell manufacturing, creating a fully integrated US value chain from cells to complete systems.
