Silveray secures £4m seed extension led by Northern Gritstone to fund product launch
Northern Gritstone led the seed extension round, which included participation from ACF Investors, Empirical Ventures, Deeptech Labs, and Hamamatsu Ventures.
Silveray develops digital X-ray film technology designed to transform industrial radiography through digitisation. The company creates flexible direct conversion detectors that convert X-rays into digital images at the point of use.
Silveray has secured £4m in a seed extension round led by Northern Gritstone to prepare for its inaugural product launch next year. The funding comes from a consortium that includes existing backers alongside new deep tech participants. The capital will enable the business to finalise development of its flexible digital X-ray detectors for industrial applications.
Originally founded at the University of Surrey before relocating to Greater Manchester, the company aims to replace traditional radiographic film with point-of-use digital imaging. The technology allows detectors to wrap around complex structures such as pipes to identify structural defects efficiently. Management expects the firm to achieve commercial revenue generation following the 2025 product rollout.
From the founder
"Silveray’s initial goal is to digitise radiographic film, so that radiographers are no longer restricted to exposing, developing, viewing, and storing film. Early customer engagement in industrial means we are confident of becoming revenue generating in 2025 and Northern Gritstone’s investment will help us achieve that."
