Global FinTech company SumUp has made a series of strategic executive appointments at its Dublin office in order to reinforce its European operations. Niall Mac an tSionnaigh has been named as the CEO of SumUp Limited, while Alastair Nolan, former executive director at Morgan Stanley, will serve as the head of finance. Claire Gillanders has been promoted as the head of compliance and Jessica Cotta is now the chief risk officer for SumUp Limited. Long-time employee Gareth Walsh has transitioned to being a non-executive director, while Siona Meghen has joined the SumUp Limited board as an independent non-executive director.
Ireland is strategically significant for SumUp, with the Irish entity seen as the 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. He expressed his commitment to keeping SumUp focused on empowering small businesses to thrive in the digital economy.
Nolan joined SumUp in May and will use his decade-long experience at Morgan Stanley to steer the company as the head of finance. Gillanders has moved to head the compliance department after working at SumUp’s risk organisation for four years. Before SumUp, she worked in risk at Citi and PTSB, both based in Dublin offices.
Overall, SumUp’s executive appointments reaffirm the company’s vision of generating innovative payment solutions for small businesses. These changes will enable SumUp to maintain its position as an industry leader by prioritising customer satisfaction and digital innovation.
