Delta.g secures £4.6 million in seed round to advance quantum sensing platform

Delta.g, a spin-out from the University of Birmingham, has raised £4.6 million in an oversubscribed seed round to support the commercialisation of its quantum sensing platform. The round was led by Serendipity Capital with participation from NSSIF and existing investor SCVC.

The company’s technology, developed at the UK Quantum Technology Hub for Sensors and Timing, has moved from laboratory development to field deployment. It has been engineered to reduce size, cost, and power requirements while being tested for real-world applications. Early trials have demonstrated use cases across infrastructure, transportation, and dual-use sectors.

Tony Lowe, CEO of Delta.g, said: “We’re thrilled by the strong investor support at this early stage. This raise is more than capital; it’s a vote of confidence in our mission to make quantum sensing operational. We’re building the tools to see what others can’t, in places that matter most, from hidden sinkholes to critical infrastructure. With this funding, we’re accelerating our roadmap to deliver smaller and more nimble field-ready systems.”

The company plans to expand its technical team and manufacturing capacity, deliver field systems through pilot deployments with commercial and government partners including the UK Department for Transport, and advance its data and analytics platform to integrate geospatial insights.

Rob Jesudason, CEO and Founder of Serendipity Capital, said: “Delta.g serves as yet another proof point of UK leadership in quantum and dual use technologies. Our investment reflects our firm belief that the multi-year investment by the UK Government in quantum technologies combined with the UK’s world class scientific talent, Universities and research institutions is producing companies that have the potential to obtain global leadership. Delta.g’s scientific co-founders Prof. Mike Holynski, Dr Jonathan Winch and Dr Andrew Lamb are truly world class in their field. We look forward to working with Delta.g and helping it to realise its groundbreaking potential.”

John Williams, SCVC General Partner, said: “Delta.g is a perfect example of our thesis in action – backing transformative science early, building the company around it, and supporting the leadership to turn breakthrough ideas into impact. This milestone reflects years of hard work by an exceptional team.”

An NSSIF spokesperson added: “We’re delighted to support Delta.g’s quantum sensing technology that has a range of potential dual-use applications. As a strategic investor, we’re looking forward to supporting the next stage of the technology development and company growth.”

The investment underscores interest in quantum sensing as a tool for sectors including defence, energy, and infrastructure, where access to reliable spatial intelligence remains limited.
