Delta.g Secures £4.6 Million to Advance Quantum Sensing

University of Birmingham spin‑out Delta.g has raised £4.6 million in an oversubscribed seed round to accelerate the commercialisation of its pioneering quantum sensing technology

Led by Serendipity Capital, with participation from NSSIF and existing investor SCVC, the round signals growing momentum behind quantum sensing as a practical tool for both government and industry. Delta.g’s breakthrough platform, developed at the UK Quantum Technology Hub for Sensors and Timing, has successfully moved from laboratory research into real‑world field testing.

The company’s quantum sensor is engineered to deliver real‑time spatial intelligence while reducing size, cost, and power requirements. Early trials have demonstrated applications across infrastructure, transportation, and defence, with potential to transform how organisations detect, measure, and navigate in complex environments.

CEO Tony Lowe welcomed the investment, noting that the capital will enable Delta.g to expand its technical team, scale manufacturing, and deliver pilot deployments with key industry and government partners. These deployments will showcase how quantum sensing can provide sovereign capability in areas such as GPS‑free navigation, subsurface imaging, and environmental monitoring.

For NSSIF, backing Delta.g reflects our commitment to supporting the UK’s quantum ecosystem and investing in dual‑use technologies with both commercial and strategic potential. Quantum sensing is a critical enabler for National Security and Defence, and Delta.g’s progress demonstrates how UK innovation can deliver world‑leading capability.

This seed round marks a significant milestone for Delta.g and for the UK’s broader quantum strategy. By bridging cutting‑edge science with practical deployment, Delta.g is helping to ensure the UK remains at the forefront of quantum technology.
