Founded in 2023 out of a collaboration with Cummins Turbo Technologies, Holdson develops electroform™, an acid-free electrochemical polishing technology that enhances metal parts by removing surface imperfections, boosting fatigue life and enabling the finishing of intricate internal geometries. Its equipment and services help manufacturers streamline post-processing, reduce manual intervention, and scale production of both additively manufactured and traditionally cast parts. The company already serves customers across the UK, Europe, the United States and Asia and has grown to a team of 18 employees. Key sectors addressed include aerospace, defence, medical, energy and nuclear fusion, where demand for stronger, more reliable components continues to rise. Holdson positions its technology as a cost-competitive alternative that supports higher volume production and increasingly complex designs. With fresh capital, management plans to expand manufacturing capacity for its electroform devices and deepen market penetration across advanced manufacturing verticals. Although no revenue figures have been disclosed, rapid customer adoption and investor backing suggest growing commercial traction.
