Reinventing mobile banking with ML
HSBC · Hong Kong
HSBC used Azure Databricks and Delta Lake to unify data analytics across data engineering, data science and analysts for its PayMe mobile payments app, applying NLP and machine learning for fraud detection, personalization and recommendations. Data processing for complex analytics dropped from 6 hours to 6 seconds, 14 read replica databases were consolidated into one Delta Lake, and app engagement improved 4.5x.
Overview
HSBC used Azure Databricks and Delta Lake to unify data analytics across data engineering, data science and analysts for its PayMe mobile payments app, applying NLP and machine learning for fraud detection, personalization and recommendations. Data processing for complex analytics dropped from 6 hours to 6 seconds, 14 read replica databases were consolidated into one Delta Lake, and app engagement improved 4.5x.
The challenge
HSBC struggled to overcome scalability limitations that blocked it from making data-driven decisions for its PayMe mobile payments app: legacy systems left data science teams working with data that was weeks old after manual, time-consuming exports; every data request required a manual, error-prone approval and masking process; data scientists worked in silos on custom environments, limiting collaboration and slowing model iteration; and data analysts struggled to get the structured data subsets they needed for business intelligence and reporting.
The solution
With Azure Databricks, HSBC unified data analytics across data engineering, data science and analysts, using NLP and machine learning to understand the intent behind each PayMe transaction and power recommendations, personalization and fraud detection. Delta Lake enabled real-time, secure anonymized data masking for data science and analyst teams and gave HSBC performant, scalable pipelines for downstream analytics and ML, while auto-scaling clusters improved operational efficiency across the machine learning lifecycle.
Reported business value
Complex analytics processing time dropped from 6 hours to 6 seconds, 14 read replica databases were consolidated into a single Delta Lake, PayMe became the #1 app in Hong Kong with 60% market share, and network science-driven personalization improved app engagement 4.5x.

TBC Bank Operationalizes Trusted Data with Lakebase
TBC Bank, the largest banking group in the Caucasus region, built a Lakehouse on Databricks and adopted Lakebase and Databricks Apps to move from on-premises SQL Server instances and month-long reporting cycles to self-service analytics and AI-driven applications, including a web-based AI chatbot and AutoML-based credit risk scoring. Credit risk model deployment fell from 14 weeks to two days, and more than 600 users regularly query governed data through Genie.
ING Bank transforming operations through agentic AI
ING Bank is running multiple AI projects across operations, governed centrally under its COO. Live/early-production efforts include a retail chatbot, AI-driven identification of hidden affluent clients for marketing, AI-assisted transaction monitoring that helps investigators close standard alerts faster and focus on risk, and a customer due diligence (KYC) redesign that uses existing public and behavioural data to auto-answer most of a roughly 100-question review, cutting due diligence from days or weeks to seconds. ING is also developing agentic AI to handle mortgage applications end-to-end (credit checks, data collection) starting in 2026. ING's COO said AI introduced to an operations process yields a 25% productivity gain, with freed capacity redeployed to growth and more complex work, and its CTO described 'conservatively aggressive' governance restricting AI exploration to five areas under COO control.
Hyundai Capital America: Transforming customer experience with messaging innovation
Hyundai Capital America (HCA), the finance arm of Hyundai Motor Group for Hyundai, Kia and Genesis leases and loans in the US, partnered with LivePerson starting from a 2018 proof of concept to shift from a voice-dominated contact center to a data-driven, messaging-first strategy across SMS and Apple Messages for Business. Using deflection-to-messaging on high-friction payment interactions, HCA achieved 94% customer satisfaction, an 89% containment rate, and grew messaging engagement from 10,000 to over 100,000 customers served monthly. HCA and LivePerson co-developed a PCI-compliant chatbot debit card payment integration with payment processor ACI.
