UK-based Delta.g Raises £4.6M Funding In Pre-Seed Round

The funding was led by Serendipity Capital, with support from NSSIF and existing backer SCVC.

Quantum sensing is emerging as one of the first quantum technologies with real-world impact, advancing subsurface imaging, navigation, and environmental monitoring. However, sectors like infrastructure, energy, and defence still lack reliable, high-resolution spatial data, leading to costly risks and delays.

Delta.g addresses this with quantum sensors offering unmatched precision, portability and reliability. Spun out of the University of Birmingham’s Quantum Technology Hub for Sensors and Timing, its proprietary platform is engineered for real-world conditions. Early trials already show strong value across infrastructure, transportation, and dual-use applications.

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 said Tony Lowe, CEO, Delta.g.

Under the leadership of CEO Tony Lowe, Delta.g is building a quantum sensing platform that delivers breakthroughs in precision, portability, and reliability. Spun out of the University of Birmingham’s Quantum Technology Hub for Sensors and Timing, its proprietary technology is built for real-world use and has proven value in infrastructure, transportation, and dual-use applications.

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.”
