Skeleton Technologies hits $1B valuation with Siemens backing
Siemens has announced a strategic investment in Estonian energy storage company Skeleton Technologies, leading a new funding round that values the company at over $1 billion (over €899 million), making it a unicorn. The exact amount was not disclosed, but CEO Taavi Madiberk described it as a "nine-digit investment round" (at least $100 million). As part of the deal, Siemens will become the exclusive worldwide distributor of Skeleton's products in the data center market, integrating its supercapacitors into Siemens' electrical infrastructure portfolio. These supercapacitors address power spikes from AI data centers, offering up to 40% energy savings. The fresh capital will primarily be used to expand US manufacturing and R&D, including a dedicated cell manufacturing facility. Building on a long-standing partnership, the companies will develop power systems for next-generation AI data centers, addressing challenges like rapid load swings and harmonics. Skeleton's proprietary Curved Graphene technology aims to improve energy efficiency and GPU performance, reflecting a broader trend of European startups funding AI infrastructure. The deal is subject to customary closing conditions.
The investment underscores the growing importance of power infrastructure for AI data centres, a critical area for AdTech and MarTech as AI workloads expand. While not directly ad-related, it highlights a trend that could affect digital infrastructure.
