Nigeria’s fraud problem is forcing fintechs to rethink growth

For years, Nigeria’s fintech boom has been powered by rapid product launches, aggressive customer acquisition, and a race to scale digital channels before competitors do.

But as fraud grows more sophisticated and coordinated, that playbook is increasingly being tested.

Across Nigeria’s fast-moving digital finance ecosystem, fraud has become less about isolated bad actors and more about organised networks exploiting new products almost as soon as they launch. The result is a growing tension for fintechs: how to keep growing without tightening controls so aggressively that legitimate customers are locked out.

That pressure is now forcing a rethink of how growth itself is designed.

One company leaning into that shift is Oxygen X, the credit-led fintech subsidiary of Access Holdings, which has built its expansion strategy around proactive fraud prevention rather than reacting after losses occur.

Licensed by the Central Bank of Nigeria as a finance company, Oxygen X operates within a highly regulated environment while supporting consumer and SME growth through structured credit and fixed-term investment products.

As it expanded its digital and mobile channels, the company made an early decision to embed fraud detection directly into its core infrastructure, rather than treating it as a bolt-on control.

According to the company, the approach has paid off. Over a six-month period, Oxygen X recorded nearly four-fold revenue growth while improving approval rates by around five percent, an outcome that challenges the assumption that stronger fraud controls must come at the expense of customer experience.

“Fraud in Nigeria doesn’t stand still, and a lot of the most harmful activity looks perfectly normal in isolation. What has mattered for us is being able to surface coordinated behaviour early, before it escalates, instead of discovering it after losses have already happened,” said Daniel Watts, chief risk officer at Oxygen X.

Traditional fraud systems in Nigeria have relied heavily on static rules that are slow to change and often generate large volumes of false positives. While such rules remain necessary, risk leaders say they struggle to keep up with evolving fraud tactics that span multiple accounts, devices, and customer journeys.

In Oxygen X’s case, the company deployed Archer as its core fraud detection and investigation platform, embedding it into backend systems and daily risk workflows. The platform enables real-time monitoring, behavioural clustering, and entity resolution, tools designed to identify patterns that would otherwise appear benign when viewed account by account.

That shift reflects a broader industry reality. As regulators raise expectations around fraud prevention and consumer protection, licensed fintechs are increasingly expected to demonstrate not just compliance, but active anticipation of risk.

“Controls usually go live after something has already gone wrong, that is how most fintechs operate in fast-moving markets. Oxygen X wanted to catch risk they hadn’t seen before, while still keeping legitimate customers moving quickly,” said Zacii Dijesse, CEO and co-founder of Archer.

Beyond fraud prevention, Oxygen X says the proactive approach has allowed it to scale operations without increasing headcount, as analysts spend less time investigating low-quality alerts and more time focusing on genuine risk. The same infrastructure is now being extended to support anti-money laundering and compliance workflows, consolidating multiple risk functions into a single operational framework.

For Nigerian fintechs, the implications go beyond any one company. As fraud becomes more coordinated and opportunistic, growth strategies built purely around speed are proving harder to sustain. The emerging lesson is that risk management is no longer just a defensive function, it is becoming a prerequisite for sustainable scale.

“The goal isn’t fewer users. It is more legitimate users who can keep using your product as you grow,” Dijesse said.

In a market where fraud often moves as fast as innovation itself, Nigeria’s fintech sector is being pushed toward a new equation for growth, one where anticipating risk early may be just as important as launching the next product.
