Delta g Secures £1.5m Funding to Accelerate Supply of Quantum Sensors for Gravity Gradiometry Platform

Delta g Secures £1.5m Funding to Accelerate Supply of Quantum Sensors for Gravity Gradiometry Platform

Delta g, a start-up that has developed technology to map complex sub-surface and unseen locations, has secured £1.5m in funding to accelerate the supply of its quantum sensors.
The funding round was led by Science Creates Ventures, with investment from Quantum Exponential Group, Newable Ventures, Bristol Private Equity Club, and a number of angel investors.

Delta g's gravity gradiometry platform, also known as "Google Maps for the underground," has the potential to save time and money on major infrastructure projects.

The company points out that delays and reduced productivity on such projects can result from poorly understood sub-surface areas, with significant costs associated with such issues.

The new funding will be used to launch real-world trials with major industrial clients to help commercialize the technology.

In addition to the capital from investors, Delta g has also been awarded a grant from Innovate UK worth approximately £500,000 to accelerate the delivery of a commercial product.

"The UK would massively benefit from delivering major infrastructure projects on time and on budget, and through increased productivity by reducing the time it takes to bring such projects to the point of benefiting people," said Pete Stirling, co-founder and CEO of Delta g.

"A big part of this is the difficulty found in mapping the complex unseen environments and hidden critical infrastructure that resides under the ground." Existing technologies for underground surveys are limited in their efficacy due to inconsistency, prolonged measurement times, and reactive use, according to Delta g.

The company's quantum sensors offer a more accurate and efficient solution to this problem, with the potential to create a significant impact in mapping the underground.

"Delta g has created a truly category-defining breakthrough in gravity measurements via quantum sensing, which has the opportunity to create an enormous impact in mapping the underground," said Harry Destecroix, founder of Science Creates Ventures.

Delta g's technology has the potential to benefit a range of industries, including construction and utilities.

With the new funding, the company will be able to further develop and commercialize its product, potentially revolutionizing the way that underground spaces are mapped and understood.
