Jan de Vries · 2026-05-07

Skeleton Technologies, an AI infrastructure and grid power systems provider based in Tallinn, Estonia, just scored a major win. The company announced the first close of a larger funding round at $35.8 million (€33 million). That brings its total venture capital haul to $424 million as it gears up for an initial public offering (IPO) in the United States in 2027. ### What This Funding Means for Skeleton This new round is more than just cash. It expands Skeleton's investor base with three big names: Axon Partners Group, SmartCap, and Taiwania Capital. And there's more to come. The company plans to announce additional investors as part of a larger round before the IPO. Taavi Madiberk, CEO and co-founder of Skeleton Technologies, shared his excitement: "As AI infrastructure continues to scale, reliable, high-performance power solutions have become critical. 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 centre energy consumption by 40%, increase computing power by 40%, and enable faster power grid connection." ### Powering AI Data Centres with Breakthrough Tech Skeleton's core technology is something special. Founded in 2009, the company claims to be the world's largest manufacturer of supercapacitors for mission-critical infrastructure and industry. Their energy storage systems use patented Curved Graphene and supercapacitor technology. These systems support AI, grid stability, frontline defence, space exploration, and more. The company protects its innovations through 70 patent families. David Weng, CEO at Taiwania Capital, explained the strategic importance: "Taiwan acts as the global hub for the AI data centre supply chain, while Europe is a powerhouse of deep-tech innovation. We view Skeleton's technology as a critical solution for enabling the next generation of AI infrastructure. By backing Skeleton Technologies, we are connecting their breakthrough energy solutions with Taiwan's robust AI data centre supply chain. Together, we are building the resilient energy backbone needed to unlock the full potential of the AI era." ### Key Benefits of Skeleton's Solutions - **40% reduction** in energy consumption for AI data centres - **40% increase** in computing power with their GrapheneGPU solution - **Faster grid connection** and greater independence from power constraints - **No reliance** on lithium, cobalt, nickel, or other scarce critical raw materials ### The Road to the US IPO Skeleton is preparing to expand production to the United States, adding to its existing mass-scale supercapacitor manufacturing in Germany and a one-gigawatt SuperBattery factory in Finland. The company says its solutions are already being delivered to AI data centre customers in Europe and Asia, in addition to the US market. Madiberk noted, "While the US, with its large hyperscalers, is the leader in AI globally, our solutions are being delivered to AI data centre customers in Europe and Asia, as well. The power bottleneck is limiting growth across the entire AI market, driving the accelerated demand for our solutions, and the backing of our strong investor base is essential in supporting our fast growth." Skeleton claims it now has the largest engineering team and the largest R&D team in the high-power energy storage sector. As AI workloads become more power-intensive, infrastructure efficiency is emerging as the key competitive factor. The company's solutions are built on trusted European and transatlantic supply chains, limiting strategic dependency risks. For professionals tracking EU Inc news and startup incorporation trends, Skeleton's journey from a Tallinn-based startup to a US IPO candidate is a compelling story. It shows how European deep-tech innovation can scale globally, especially when targeting the US market.
