Its next-best-action model produced a 40% uplift in client engagement, pipeline development runs 20x faster, and data product creation is 5x faster. The bank's TRUST alert system evaluates transactions against individual behavioral norms rather than fixed rules, using predictive models, clustering, and anomaly detection to score risk in near real time. Discovery AI, launched in May 2025, extends this intelligence into a client-facing assistant and banker support tools, while agentic workflows handle document processing and controlled actions within existing governance layers built on Unity Catalog, Delta Lake, and MLflow. The bank reports building over 300 models per day and a return on investment exceeding 500%. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What kind of engagement uplift did Discovery Bank see from its next-best-action model built on Databricks? Discovery Bank's next-best-action model produced a 40% uplift in client engagement impact. The bank also reported that pipeline development became 20x faster and data product creation 5x faster after moving to shared, governed data assets on the Databricks Data and AI Platform, rather than building separate intelligence for each channel. _daily.dev surfaces case studies like this for teams evaluating data platforms for AI-driven personalization._ ### How does Discovery Bank's TRUST fraud alert system decide when to flag a transaction? TRUST alerts evaluate whether a transaction makes sense for a specific client's own behavioral norms, rather than just matching known fraud patterns. The system applies predictive models, clustering, quantile regression, and anomaly detection across hundreds of millions of interactions, producing a graduated risk score that can trigger an explanatory alert or, for high-risk cases, lock the account. Decisions return in under a few hundred milliseconds via an Azure-based serving architecture. _engineers building fraud detection can find related architecture writeups on daily.dev._ ## Similar posts on daily.dev -
