Summary

ISDI Limited, based in London, UK, is a holding company with an active status, established fourteen years ago in July 2010. The company employs twenty-eight people and holds assets totaling £14,775,626. It operates from a real address at Highgate Business Centre and is overseen by five directors and two owners. ISDI is a regular importer and exporter, specializing in electrical machinery and equipment, with nineteen months of import activity and sixteen months of export activity recorded, the last operations both occurring in January 2025.

ISDI’s core business revolves around the design and manufacture of high-performance X-ray detectors and CMOS image sensors. Through its subsidiary, Spectrum Logic, ISDI offers CMOS X-ray detectors for medical, industrial, and scientific applications. The company also designs and manufactures CMOS image sensors and other ASICs for the detection of X-rays, visible light, electrons, and protons, offering custom design services to meet specific customer requirements. Their website highlights wafer-scale image sensors and sensor arrays, alongside case studies and news updates on collaborations and industry events.

Financially, ISDI Limited presents a mixed picture. While net assets increased by 45% to £6.2 million, indicating growth in equity, several key metrics show signs of pressure. Cash bank on hand decreased significantly by 57% to £190,000, and accrued liabilities deferred income rose by 30% to £160,000. Trade debtors fell by 22% to £6.8 million, suggesting improved collections, but bank borrowings increased by 45% to £3.1 million. The company’s average number of employees increased by 18% to thirty-three, possibly reflecting increased demand or expansion efforts. The company’s fixed assets increased by 11% to £1.2 million.

The rise in bank borrowings, coupled with the decline in cash reserves, suggests ISDI might be investing heavily in growth or facing increased operating expenses. The decrease in trade debtors is a positive sign, but the overall trend warrants closer monitoring. With no auditor mentioned, the financial information relies on unaudited data, which limits the level of assurance. Overall, ISDI Limited appears to be a dynamic company navigating the challenges of growth and investment, with its future success dependent on its ability to manage its financial resources effectively.

Registered in England/Wales under the registration number 07314677, with a registered address at NW5 1LB, England, London, Highgate Business Centre, 33 Greenwood Place.
