Holyvolt

Holyvolt is a Swedish-German cleantech company founded in 2022 by Mathias Ingvarsson, Hans Victor, and Peter Lilliehöök, developing a proprietary Nanopaste-Printing™ technology for energy generation and storage. The company operates from offices in Stockholm and a research and development lab in Munich, focusing on manufacturing next-generation solar cells, battery cells, and heating elements.

The founders bring a diverse entrepreneurial background to the venture. CEO Mathias Ingvarsson is a serial entrepreneur, while Hans Victor previously founded the digital veterinary clinic FirstVet and FlowMotion Technology. Peter Lilliehöök has a background in venture capital consulting. The company has attracted significant attention and funding from high-profile investors, including Volvo, the Wallenberg family's investment firm FAM, and iZettle founder Jacob de Geer. Holyvolt secured approximately €9.5 million in 2023 and followed up with a €12 million round in early 2026, reaching a valuation of €182 million. Despite being in a research and development phase, the company reported over €5 million in net sales in 2024 from the sale of machinery and equipment to an industrial partner.

Holyvolt's core technology platform combines screen printing with high-throughput material discovery to produce high-performance energy solutions at a lower cost and with a reduced environmental impact. A patent filed in May 2025 details a flexible, lightweight, screen-printed solid-state battery that avoids the use of lithium, cobalt, nickel, and rare earth metals. This technology uses nanoparticles for the cathode and anode materials, which is claimed to improve adhesion and flexibility. The process is designed to be simple, scalable, and less energy-intensive than conventional manufacturing. Potential applications are vast, ranging from consumer electronics and electric vehicles to heated wallpaper and solar-powered blinds. The company's business model is B2B, focusing on producing and selling products, services, and intellectual property related to energy and environmental technology.
