Delphi personalization engine for customer offers

TTB's Delphi engine raised highly targeted offers tenfold and doubled digital sales growth

WorkingVendor case studyVendor ↗

Problem

TTB's on-premises systems limited personalized services to 500,000 customers. Batch processing left a two-day data lag and could not handle streaming data.

Approach

TTB moved its in-house Delphi Personalization Engine and more than 1,000 tables to a lakehouse on Azure Databricks. Delphi handles product recommendations, propensity scoring, fraud detection and customer engagement across channels. Real-time processing let the bank act on customer events as they happened.

Results

10xincrease in highly targeted offers, per DatabricksVendor case study[1]
2xfaster digital sales growth, per DatabricksVendor case study[1]

Takeaway

TTB rebuilt the data layer under an engine it already ran. The engine then reached the wider customer base it had been unable to serve.
