The Nigerian banking sector is going through a significant transformation. As competition increases, banks realize they need to go beyond just offering products and start understanding their customers more personally. Leading this change is Robert Aderinmola, whose work in customer insights and analytics is changing how banks should engage with their large customer base.

“In a crowded market, knowing your customer isn’t a luxury; it’s a necessity,” says Aderinmola, Team Lead for Customer Insights and Analytics at Diamond Bank Plc. Financial institutions often have detailed data on millions of customers, yet they tend to treat them as essentially the same. The result is misallocated marketing budgets, product offerings that miss the mark, and a whole segment of profitable customers who are invisible to traditional analytics.

Keen on addressing customer concerns, Aderinmola’s solution is a highly detailed, data-driven customer segmentation project. His team isn’t just looking at basic demographics; they are analyzing spending habits, transaction history, channel usage, and overall profitability. The goal is to shift from broad categories to nuanced segments, allowing the bank to tailor products and services with precision.

His approach combined econometric modeling with behavioral segmentation, moving far beyond standard demographic categories. The team analyzed transaction velocity, how frequently customers moved money, and through which channels.

They mapped spending elasticity, how sensitive different customer groups were to fees, interest rates, or service quality. Most critically, they developed profitability indices that revealed which customers generated sustainable long-term value versus those who appeared profitable on surface metrics but drained resources through high servicing costs.

The results were immediate and quantifiable. By identifying, analyzing, and evaluating consumer trends across retail, business, and corporate banking, Aderinmola’s work is revealing market opportunities. This is not a hypothetical number, but a direct result of insights that help the bank understand where and how to grow. This aligns with wider industry trends.

This work aligned with Nigeria’s National Financial Inclusion Strategy, which had identified a critical gap: traditional banks were failing to reach underbanked and unbanked populations not because these customers lacked potential, but because institutions lacked the analytical tools to identify and serve them profitably. Aderinmola’s segmentation model provided exactly that capability.

“The real insight wasn’t just who our customers were,” Aderinmola notes. “It was understanding the trajectory they were on, where they were headed financially, and how we could provide relevant services at each stage of that journey.”

Aderinmola’s work is precisely the type of strategic initiative that meets this need, allowing the bank to target segments with specific financial needs, rather than with a one-size-fits-all approach. Beyond raw market opportunity, the innovative approach is driving a better customer experience.

“Analytics helps us see which channels are working and which aren’t,” Aderinmola states. “It informs everything from how we communicate with a customer to how we design the user experience for a new digital product.”

By measuring and evaluating customer activity, product portfolio performance, and channel usage, the team is directly influencing key strategic and business development projects. Their work provides insights that help guide decisions, ensuring the bank is not only profitable but also deeply relevant to its customers.

For the bank, Aderinmola’s segmentation project is more than just a business development initiative. It is a long-term investment in understanding its customers better than anyone else, positioning it for lasting success in a rapidly evolving financial landscape.
