Danish startup Skycore Semiconductors has raised €5 million in seed funding to advance its Power Integrated Circuit (IC) technology, designed to meet the escalating energy demands of next-generation AI data centres.
The round was led by the Amadeus APEX Technology Fund, with participation from First Momentum, Mätch VC, and Balnord. Including previous funding and grants totalling €2.5 million, the company has now raised around €7.5 million to date.
Skycore, founded in Denmark, develops Power ICs that enable high-efficiency, high-density power delivery for 800V High Voltage Direct Current (HVDC) data centre architectures. These emerging systems are seen as a key enabler for AI infrastructure, which is increasingly constrained by the limits of conventional 54V power distribution.
Pere Llimós Muntal, Skycore’s Chief Executive and Co-founder, said the company’s technology “delivers power solutions with extreme power density and efficiency in flat, compact form factors,” enabling the shift to HVDC systems. “This funding enables us to accelerate our market entry from validated silicon to market-ready products, positioning Skycore as a key enabler of next-generation data centre power delivery,” he said.
Ion Hauer, Principal at APEX Ventures, said Skycore’s technology represented “a paradigm shift for 800V data centre architectures and beyond,” adding that the company was “solving the power bottleneck that’s limiting AI’s explosive growth.”
Skycore plans to use the new capital to expand its team, strengthen manufacturing and product development capabilities, and build out its patent portfolio. It will also work with strategic partners and potential customers on co-development projects.
The move comes as the data centre industry races to adopt 800V HVDC power distribution to accommodate racks exceeding 200kW. In a recent announcement, Nvidia endorsed 800V architectures as key to improving energy efficiency and scalability in AI computing facilities.
Founded by a team of power electronics specialists, Skycore operates as a fabless semiconductor company, relying on foundry partners for chip production. Its technology platform has been silicon-validated and is supported by six patent families.
The eight-person firm is a member of the Open Compute Project (OCP) and the Berkeley Power & Energy Center (BPEC) at the University of California, joining industry players such as Nvidia, Google, Intel, and Analog Devices.
Skycore aims to establish itself as a global leader in high-voltage Power IC solutions for data centres and other applications with extreme power demands.
