Higher investment by FinTech firms is not accounted for by sectoral focus or differences in firm age. Reasons for higher customer capital investment are explored, including the need to build trust with customers, the focus on downstream segments of the financial marketplace, the operation of platform-based business models, and a heavier reliance on valuable customer data.
