The challenge
Tesco held the richest customer database in retail — 12m Clubcard members — and wanted it to do three things at once: open new revenue lines, deepen loyalty across the base, and defend market share against aggressive competitor store expansion.
What we did
Ran multi-objective credit targeting — mid-credit-score customers in high-revolver neighbourhoods, test-and-learn to optimise simultaneously for response, profitability and underwriting approval. Personalised at 12m scale, segmenting by lifestyle, lifestage and recency-frequency-value with fraud controls. Used GIS drive-time and customer-value modelling to retain high-value shoppers in contested neighbourhoods.
The outcome
- Financial Services launch: new revenue line $0 → $63m in 12 months; 10,000 customers acquired at under $6 each
- Clubcard statement: 12m statements personalised, $126m+ in reward vouchers distributed at national scale
- GIS store defence: 50% of at-risk revenue protected across 50 towns where competitors opened stores
