Marketing Personalization
NatWest Group had strong customer insights and a digital foundation, but turning those ideas into relevant customer engagement still required navigating hundreds of datasets, manual rekeying, forms, and more than 10 cross-team handoffs, making campaigns slow to launch and often irrelevant to customers.
Reported impact
NatWest compressed its idea-to-value cycle from 60-100 days to 1 day, reduced staffing and handoff overhead dramatically, and gave customer teams a practical way to scale more relevant engagement across 18 million customers while building on evidence that better personalization can improve lifetime value and customer satisfaction.
NatWest Group worked with Bain to replace a handoff-heavy campaign process with an AI-enabled customer engagement workflow built on the bank's existing digital foundation. The implementation starts with a 360-degree customer view assembled from hundreds of internal datasets. Machine learning and generative AI use that context to identify customer needs and support intelligent triggers tied to key life-cycle moments. On top of that foundation, the bank deployed a purpose-built AI tool for customer mission teams that lets them inspect insights, model engagement strategies, turn promising ideas into live tests, and continuously measure results. Agentic AI automates much of the manual translation between data, strategy, and channel execution, so a small team can move directly from insight to action while still optimizing what works across NatWest's customer-facing digital channels.
Hundreds of internal customer datasets feed NatWest's 360-degree customer view, where machine learning and generative AI derive insights and triggers. Those outputs flow into a purpose-built AI tool used by mission teams to model strategies, launch tests in digital channels, and measure which customer engagements are most effective.
