Banks' "Know Your Client" (KYC) processes are often touted as industry-leading, but despite collecting vast amounts of customer data, banks struggle to offer personalized experiences or timely loan approvals. The main issue lies with outdated manual processes and legacy systems that hinder automation and data-driven decisions. Banks create comprehensive client profiles during onboarding but fail to utilize this information to personalize offers. Instead, they default to 30+ year-old "new client onboarding" processes. To overcome these challenges, banks plan to invest in real-time analytics, AI/ML, digital customer experiences, and modernization of their data architecture, with MongoDB Atlas being a suitable solution for building comprehensive customer 360 models that integrate transactional and process workloads.
