Swansea Building Society appoints leading fintech entrepreneur to board

03 August 2026

Swansea Building Society has appointed experienced financial technology entrepreneur and business leader Martin Breach as a Non-Executive Director.

A Swansea resident, Martin brings more than 13 years of senior leadership experience in the financial services and technology sector, having helped banks, building societies and finance providers across the UK and internationally modernise their operations, improve customer services and navigate complex regulatory environments.

His appointment further strengthens the Society's expertise in technology, digital transformation and governance as it continues to invest in new services and digital capabilities while remaining committed to its mutual values and strong local presence across Wales.

Martin most recently served as Managing Director and shareholder of Oyster Bay Systems and Profile Data Services, specialist financial technology businesses that delivered mission-critical lending and account management systems to financial institutions operating in 12 countries. He successfully led the growth of the businesses before overseeing their sale and integration into the Aryza Group.

During his career, Martin has worked with a range of financial institutions, including building societies, banks and specialist lenders, delivering major technology transformation programmes, infrastructure upgrades, data migrations and process improvements. His experience spans strategic leadership, risk management, governance, operational improvement and digital innovation.

Martin holds a First Class BEng degree in Manufacturing Systems Engineering from the University of Wales Trinity Saint David and has built a reputation for delivering sustainable growth, operational excellence and customer-focused innovation throughout his career.

His appointment comes at a time when Swansea Building Society continues to expand its range of services, including the development of competitive online savings products that enable customers across Wales to benefit from the Society's mutual approach while accessing modern digital banking services.

Commenting on his appointment, Martin Breach said:

"Having spent my career helping financial services organisations embrace technology and adapt to changing customer expectations, I am delighted to be joining Swansea Building Society's Board.

"As someone who lives in Swansea and has seen first-hand the decline of locally based financial services over the years, I have enormous respect for the role the Society continues to play in supporting individuals, families and businesses across Wales.

"One of the things that attracted me most to the role is that important decisions affecting members are still being made here in Wales by people who understand the communities they serve. Swansea Building Society has a proud history, strong values and an exciting future, and I look forward to helping the Society continue to evolve while remaining true to those principles."

Stephen Maddock, Chair of Swansea Building Society, said:

"We are delighted to welcome Martin to the Board. He combines deep expertise in financial services technology with extensive experience of leading successful businesses and delivering transformation in highly regulated environments.

"As the Society continues to invest in both its branch network and its digital capabilities, Martin's insight and experience will be invaluable in helping us meet the evolving needs of members while maintaining the personal service and local decision-making that set us apart.

"Martin also shares our commitment to Swansea and Wales, making him an excellent addition to the Board as we continue to grow and develop the Society for the benefit of current and future generations of members."

Founded in 1923, Swansea Building Society remains committed to providing savings and mortgage services through a combination of traditional branch-based service and modern digital channels, while retaining its independence and local roots.

The Society remains one of the few financial institutions in the UK that receives no wholesale funding or support from the Bank of England in the form of cheap funding. Its balance sheet is funded entirely by customer savings balances and its own capital reserves built up from retained profits over many years.
