A London FinTech recently taken over in a private equity deal has appointed former PayU boss Mario Shiliashki as CEO.

Shiliashki, a veteran of Mastercard and PayPal, joins myPOS, one of the UK and Europe’s largest providers of payments, accounts and card solutions for small merchants and sole traders.

He most recently led PayU through growth, M&A and a $610 million exit to fellow FinTech Rapyd.

Shiliashki – who is on the board of Swedish firm Fingerprint Cards and Sutton-based FX firm Crown Agents Bank – will also join myPOS’s board of directors.

“I am thrilled to be joining myPOS at such a pivotal time in its development,” said Shiliashki. “I am truly excited to work with such a strong team and to lead the business into its next stage of growth, as it continues to be at the forefront of disruption in the industry. 

“myPOS is ideally positioned to take advantage of the opportunities ahead and empower enterprises to solve their payment challenges.”
