Tandem Bank appoints Chief Technology Officer

11th December 2025

Tandem Bank has announced the appointment of Russell Strevens as its new Chief Technology Officer (CTO).

Strevens brings a proven track record in building and scaling modern technology across financial services and other regulated industries. He joins Tandem from Small World Financial Services, where he served as CTO, leading global engineering, cybersecurity and technology teams, and modernised its core infrastructure and built a cloud-first architecture for efficiency and scale. Prior to that, he was CTO at Bó, NatWest’s digital challenger, where he took its mobile banking proposition from concept to a live current account serving 10,000 users. He also spent nearly a decade at BT, rising to CIO for BT Consumer and shaping technology strategy across broadband, mobile, TV, digital services and cyber-security, playing a key role in the launch of BT Mobile, BT Sport and Ultrafast Broadband.

In his new role, Strevens will steer Tandem’s continued digital transformation, simplifying the bank’s propositions, boosting app performance and capability, and accelerating its use of AI to enhance both customer and colleague experiences.

Neil Chandler, CEO of Tandem Bank, said “Russell brings the energy, ambition and technological firepower we want at Tandem. He’s an expert at turning complex, cutting-edge tech into intuitive experiences for customers – across both challenger brands and big businesses. As we continue our journey towards being digital-first and delivering even more value for customers, we’re thrilled to have Russell on board.”
