OneSavings Bank (OSB) has launched a groundbreaking digital savings platform, empowering customers to open and fund accounts in just minutes. Developed in partnership with Publicis Sapient, the platform is part of OSB’s mission to modernize and deliver a customer-first banking experience.
Founded in 2011, OSB specializes in retail savings and specialist lending across the UK. With a vision to transform into “a bank with the soul of a fintech,” OSB is leveraging advanced technology to challenge traditional banking norms.
The new digital savings platform introduces several key features designed to improve customer experience. It enables users to register and fund accounts in under three minutes, offering seamless self-service capabilities, automated savings tools, and flexible product management. Built on the cloud-native core banking solution Mambu, and integrated with Salesforce CRM, the platform taps into an expansive fintech ecosystem, ensuring scalability and adaptability for future innovations.
Matthew Baillie, Group Chief Transformation Officer at OSB, emphasized the platform’s significance:
“The launch of our new savings platform is a major milestone in our transformation journey. It provides a secure, intuitive solution tailored to customer needs, enhancing satisfaction, operational efficiency, and conversion rates. This is just the beginning of our journey toward becoming a truly modern, tech-driven bank.”
A Fast-Tracked Transformation
Introduced to the public in October 2024, the platform was developed in just 18 months, a feat achieved through the expertise of Publicis Sapient. Selected in 2022 as OSB’s exclusive transformation partner, Publicis Sapient helped reimagine the bank’s vision, create a strategic modernization roadmap, and deliver a scalable, customer-centric platform.
Mark Smith, Vice President of Financial Services at Publicis Sapient, said:
“We’re proud to partner with OSB in delivering a dynamic, people-first solution using our SPEED approach—Strategy, Product, Experience, Engineering, Data & AI. By integrating leading platforms like Microsoft, Salesforce, and best-in-class fintech solutions, we’ve built an innovative ecosystem that enhances customer and colleague experiences alike.”
Smith added that this transformation not only delivers immediate benefits to OSB customers but also positions the bank for sustainable growth in an increasingly fintech-driven landscape.
Delivering Value to New and Loyal Customers
For Clive Kornitzer, OSB’s Group Chief Operating Officer, the platform is a testament to collaborative innovation:
“Our partnership with Publicis Sapient combines bold thinking with OSB’s 150-year legacy to deliver meaningful change. Together, we’ve embraced cutting-edge technologies to create a bank that meets the evolving needs of our customers while upholding the values that have earned their trust over the years.”
The platform reinforces OSB’s position as a market leader in financial services, setting a benchmark for customer-focused innovation in the digital age.
