SumUp Limited Bolsters Leadership Team

SumUp Limited, the Irish arm of London-based fintech SumUp, has announced key leadership appointments as part of its strategy to bolster its European operations.

Niall Mac an tSionnaigh, formerly the COO of SumUp Limited, has been appointed CEO of the Dublin-based unit. Mac an tSionnaigh brings experience from senior roles at LinkedIn and Deloitte.

Alastair Nolan, who joined SumUp Group as CFO for Europe in May, will now serve as head of finance for SumUp Limited. Additionally, Jessica Cotta, who has been with SumUp for nine years, has been named chief risk officer (CRO) of the Irish entity.

Former CEO Gareth Walsh has transitioned to a non-executive director role on the board, while Siona Meghen has joined as an independent non-executive director. Claire Gillanders, who has been with SumUp since 2020, has been promoted to head of compliance for the EU.

SumUp, which secured €1.5 billion in private credit debt from Goldman Sachs Asset Management in May, views Ireland as a key strategic hub, critical for its European market expansion. The company’s super-app serves four million merchants with card payment processing, business account services, and invoicing solutions.
