Delta.g appoints current Chair of Serendipity Capital and former HSBC Holdings Group CFO Ewen Stevenson as Chair of the Board

(Press-News.org) Delta.g, the UK quantum technology company pioneering quantum gravity sensing for subsurface intelligence, today announced the appointment of Ewen Stevenson as Chair of its Board of Directors, effective immediately.

Ewen Stevenson is a veteran banker with over 20 years of senior management experience and a record in strategic transformation, value creation, innovation, and leadership. He is currently Chair of Serendipity Capital who led Delta.g’s recently closed seed funding round.  Prior to Serendipity Capital, he served as Group Chief Financial Officer of HSBC Holdings, following four years as Group Chief Financial Officer of The Royal Bank of Scotland. Prior to this, he spent 26 years at Credit Suisse Group, where he was Co-Head of the Global Financial Institutions Group and Co-Head of EMEA Investment Banking. Ewen currently serves as Chairman of the Royal National Institute for Deaf People (RNID), reflecting his commitment to championing disability inclusion and leadership.

The appointment follows Delta.g’s £4.6 million oversubscribed seed round, led by Serendipity Capital with participation from the National Security Strategic Investment Fund (NSSIF) and SCVC.

Ewen’s appointment strengthens Delta.g’s governance and strategic readiness as it enters its next phase of growth.

Delta.g’s proprietary quantum gravity gradiometer enables high-resolution subsurface mapping by measuring tiny variations in gravity caused by hidden structures underground. The company’s technology provides a step-change in precision, speed, and reliability over conventional tools, supporting critical applications across energy, infrastructure, and defence.

Ewen Stevenson, Chair of the Board at Delta.g, said: “I am delighted to join Delta.g at this pivotal point in its journey. The company’s work in quantum sensing is world-class and demonstrates how UK university research combined with investors can be successfully translated into globally relevant industrial capability. I look forward to supporting the team as Delta.g scales its technology and builds its position as a category leader in subsurface intelligence.”

Tony Lowe, CEO of Delta.g, said: “Ewen’s appointment marks a significant milestone as we transition from seed to scale. His experience in financial governance and strategic transformation will be invaluable as we strengthen our commercial and institutional foundations. Delta.g is moving rapidly toward deployment, and Ewen’s leadership adds further confidence as we build investor, customer, and government partnerships.”

“Ewen’s appointment as Chairman reflects the unusual position Delta g occupies — a true deep-tech company that’s already commercially ready at seed stage. Having led at the highest levels of global finance, Ewen brings the experience and perspective to match the scale of what lies ahead. Serendipity Capital wasted no time in bringing him to Delta g, just one of many outcome-enhancing contributions, helping turn a category-defining technology into a category-defining company,” said John Williams General Partner, SCVC.
