In his role, Andrew will concentrate on ensuring Atom continues its journey towards “long-term profitability” and preparing the bank for a “large capital event” in the future.
Marshall has worked at the firm for around six years, initially joining as group financial controller, before becoming deputy chief executive then director of corporate finance.
During that time, he has been involved in key milestones, such as its inaugural securitisation issuance, previous capital raises, and the successful Banking Competition Remedies bid.
Before that, he worked at Barclays as a financial reporting director for around five years, and prior to that he worked at EY for around nine years in various senior roles including senior manager.
‘Next stage of Atom’s development’
McCarthy co-founded Atom in 2014 and is leaving for personal reasons. The firm said that the move “represent the next stage of Atom’s development as a business”.
Mark Mullen, chief executive officer at Atom, said: “David has been instrumental in making Atom what it is today. This is his company as much as it will ever belong to anybody and I want to thank him for his fantastic contribution over the last eight years.
“Andrew is an extremely talented member of our team and his appointment is part of the next phase in Atom’s journey. In recent months, we’ve made other changes to re-energise the senior team as we continue to evolve our business. All companies must transition from being ‘start-ups’ to ‘started-ups’ and Atom is well along that road.”
Marshall added: “I am incredibly proud and excited to take this opportunity and to join the Atom board. We have built the foundations of a great business and I will now focus on accelerating our profitable growth for the benefit of all our stakeholders.
“In such a volatile period, our mission to make the experience of borrowing and saving simpler, faster and better value is more important than ever. On a personal note, as someone who grew up in the North East of England, I share Atom’s passion for developing local talent and offering learning opportunities from our hub in Durham.”
Atom has been growing its team in recent months, hiring Andy Sturrock as chief technology officer in April this year and Rebecca Cartwright as chief risk officer in July.
It has also been undergoing a four-day work week trial, which it has described as “overwhelming positive” and, in July, Mortgage Solutions reported that Atom grew its residential mortgage assets to £1.5bn.
