FinTechAppointments

Global FinTech SumUp has reinforced its European operations with a series of strategic executive appointments based at its Dublin office. 

Niall Mac an tSionnaigh is now CEO of SumUp Limited, SumUp’s Irish operating company, and Alastair Nolan, who joined as SumUp Group’s CFO Europe, will serve as SumUp Limited’s head of finance. 

Claire Gillanders is now head of compliance after four years in SumUp’s risk organisation. Jessica Cotta was recently appointed as chief risk officer for SumUp Limited. 

Long-time employee Gareth Walsh has transitioned to being a non-executive director on the board, alongside Siona Meghen who has joined the SumUp Limited board as an independent non-executive director.

Ireland is strategically significant for SumUp, with the Irish entity operating as a gateway to SumUp’s European markets. The company has enjoyed over a decade of sustained growth and has generated positive EBITDA since December 2022. 

Mac an tSionnaigh has been with SumUp since 2022, concurrently holding the roles of VP of global operations and COO of SumUp Limited before taking over as CEO. 

Before SumUp, he was at LinkedIn for eight years, initially based in San Francisco then leading a 500-person global operations and support team from Dublin. Mac an tSionnaigh has also worked at Deloitte, Bank of Scotland and Accenture.

I am committed to ensuring that SumUp remains focused on its mission of empowering small businesses to thrive and succeed in the digital economy. 

“I am thrilled to be a part of such a talented and dedicated team, and I am confident that together we can achieve great things.”

Nolan joined SumUp in May from Morgan Stanley, where he worked for over a decade in London and Boston across equity sales and research, specialising in software and payments. His final position was executive director.

Gillanders joined SumUp in 2020, working on operational risk and compliance, rising to head of operational risk. Before SumUp, she worked in risk at Citi and then PTSB, all based in the Dublin offices.
