The partnership between Paragon Bank, a FTSE 250 specialist lender, and Mambu began in 2020, establishing a foundation of trust through the successful delivery of development finance and savings propositions. As Paragon’s savings portfolio grew, the need for a robust and reliable core banking engine became clear, leading the bank to choose Mambu as the partner for its next evolutionary step. This collaboration resulted in a greenfield transformation and the birth of “Spring,” a digital product designed to address a specific gap in the UK savings market.
Spring serves as the cornerstone of Paragon’s digital transformation, representing their first truly direct-to-consumer product with end-to-end digitization. By utilizing a greenfield approach, the bank was able to launch a new brand into a new market segment, informed heavily by customer insights. This ground-up build proved that the bank could rapidly innovate and deploy new services in a very short period of time by working in close partnership with Mambu and other key suppliers.
The development of Spring was driven by data from Paragon’s existing cohort of proactive savers. Research indicated that while consumers were interested in better rates, many were deterred by a perceived “baffle of choice” and the “perceived hassle” of moving money. Consequently, the primary objective for Spring was to create a hassle-free user experience. By focusing on a seamless customer journey and agile delivery, Spring has not only successfully gained market momentum but has also instilled greater organizational confidence in Paragon’s ability to execute large-scale digital transformations.
