For years, Nigeria’s banking sector has talked about digital transformation. What has been less clear is what a bank built around digital, not retrofitted to it, actually looks like at scale.

Optimus Bank is beginning to offer one version of that answer.

In just three years, the bank has grown from a new entrant into a business posting ₦24.14 billion in profit before tax, with gross earnings of ₦50.67 billion, up 73.53% year-on-year. Its loan book grew to ₦118.16 billion, more than doubling within a year.

The numbers, on their own, are notable. But they matter more for what they suggest: that a digital-led model can move beyond customer acquisition into balance sheet growth and do so quickly.
