Tandem appoints new CEO

Tandem Bank has announced that it has appointed Neil Chandler as its new Chief Executive Officer (CEO), subject to regulatory approvals.

Chandler brings a wealth of leadership, banking and tech experience to Tandem, spending more than 30 years in senior banking, eCommerce, retailer finance and technology roles.

He most recently served as CEO of digital bank and Banking-as-a-Service provider, Aion Bank, where he was instrumental in leading Aion Bank’s sale to UniCredit Group – one of the biggest European fintech exits in 2025.

Tandem’s Chairman, Paul Pester, said “Alex has done a phenomenal job reshaping the ‘new’ Tandem into one of the UK’s standout digital banks.

“Now with Neil on board, we’re ready for the next chapter. He’s got the pedigree, the passion, and the vision to match our ambitions – with the perfect combination of experience across technology, fintech and banking.

“We’re thrilled Neil is joining to lead our next phase of growth, securing Tandem’s status as one of the UK’s leading digital banks and furthering our mission to help many more consumers transition to a lower carbon lifestyle, while saving them money along the way.”

Departing Tandem CEO Alex Mollart said “We’ve built something special at Tandem – a profitable, high-growth fintech with a bold customer-focussed mission. The timing’s right for me to step down and I know Neil’s the right leader to take Tandem even further. I’m proud of what we’ve achieved, and incredibly grateful to the team that’s made it happen.”
