Finance and banking companies often invest less than 10% of their total engineering spend on mobile app development, despite mobile generating approximately 75% of their overall business revenue. This discrepancy highlights the need for companies to reassess their engineering budgets and allocate more resources to mobile initiatives. Investing in areas such as speed, user experience, automation, regulatory compliance, security, and innovation can help drive revenue growth. Companies that prioritize these aspects are more likely to outperform their competitors and achieve success in the fintech space. The increasing importance of mobile is changing the way companies approach engineering talent, automation, and innovation, creating opportunities for emerging fintech companies to compete with larger institutions on a level playing field.
