Skeleton Technologies, a global AI infrastructure and grid power systems provider, has announced a €33 million first close of a larger funding round, bringing its total venture capital funding to €392 million ahead of a planned U.S. IPO in 2027, as Vestbee was informed.
- Founded in 2009 by Taavi Madiberk and Oliver Ahlberg, Skeleton Technologies develops high-power energy storage systems based on supercapacitors and its proprietary Curved Graphene technology.
- The company’s products are designed to provide rapid bursts of power and fast charging cycles for applications including AI data centers, electric grids, transportation, industrial systems, and defense.
- Unlike conventional lithium-ion batteries, Skeleton’s supercapacitors store energy electrostatically rather than through chemical reactions, enabling them to charge and discharge within microseconds, withstand significantly more cycles, and operate with lower fire risk.
- Skeleton manufactures supercapacitor cells, modules, and larger energy storage systems in Germany and Finland, including its GrapheneGPU product, which is designed to stabilize power demand and reduce energy bottlenecks in AI data centers.
Details of the deal
- The funding round is intended to help Skeleton Technologies scale its high-power energy storage solutions for AI data centers, expand manufacturing capacity in Europe and the United States.
“This funding round brings additional strategic partners to the table and strengthens our ability to deliver the next generation of power solutions that cut AI data center energy consumption by 40%, increase computing power by 40%, and enable faster power grid connection,” said Taavi Madiberk.
