For years, LemFi relied on Paga’s infrastructure to help deliver naira to Nigerians receiving international transfers. That arrangement worked for both companies: LemFi gained access to an established local payment network, while Paga earned fees from processing the transactions.

That relationship now appears to be changing.

LemFi has begun moving its Nigerian naira payout infrastructure to Lemmy MFB, its affiliated microfinance bank. The change gives the remittance company greater control over how customer funds are held and transferred — and highlights a broader shift taking place across Nigeria’s fintech industry.

From renting infrastructure to owning it

LemFi's updated legal terms indicate that customers' NGN accounts may be moved between providers, including Pagatech and Lemmy MFB. Customers have also received new account numbers as part of the transition.

The significance goes beyond LemFi.

Several Nigerian fintech companies are increasingly building, acquiring or partnering closely with financial institutions that allow them to control more of the infrastructure behind their products.

Moniepoint operates a microfinance bank, while OPay also has its own MFB. Nomba operates Nombank, while Paystack has previously partnered with a commercial bank to provide virtual-account infrastructure.

The structures differ, but the strategy is similar: control more of the financial rails instead of depending entirely on another institution.

Why fintechs want their own financial infrastructure

According to fintech lawyer Adebare Akinwunmi, having an affiliated financial institution can provide several commercial advantages.

These can include lower third-party infrastructure costs, better margins, greater control over transaction volumes and a more consistent customer experience.

There is another important advantage: customer retention.

A company that controls the account where money lands can potentially offer additional financial services after a transfer has been completed.

Instead of simply facilitating a remittance and losing contact with the customer, a fintech could potentially build additional products around that relationship, including savings, payments or lending.

Regulation is also pushing the industry in this direction

The shift isn't purely about business efficiency.

Nigeria's regulatory environment has made the distinction between fintechs and licensed financial institutions increasingly important, particularly when companies want to hold customer funds or expand into products such as lending and savings.

This creates a strategic choice for growing fintechs.

They can partner with an existing bank or microfinance bank, or eventually build a financial institution of their own.

For larger and better-capitalised companies, owning that infrastructure can become increasingly attractive as transaction volumes grow.

What happens to companies providing the infrastructure?

LemFi's move also highlights a potential challenge for businesses whose revenue depends on providing financial infrastructure to other fintechs.

The model can be highly valuable when a fintech is entering a new market and needs infrastructure quickly.

But the relationship can change once that fintech becomes large enough to justify bringing those capabilities in-house.

In that situation, the infrastructure provider risks losing not just a customer but a significant source of transaction volume.

That doesn't necessarily mean companies such as Paga are at risk. Nigeria still has a large population that remains underserved by formal financial services, leaving substantial room for payment and financial infrastructure providers.

But it does mean that long-term partnerships between fintechs and infrastructure providers may become more difficult to maintain when the customer eventually has the resources to build its own rails.

The bigger picture

LemFi's transition reflects a broader evolution in Nigerian fintech.

The industry's early growth was heavily dependent on partnerships. Startups could launch products faster by connecting to existing banks, payment processors and mobile-money infrastructure.

As companies mature, however, control becomes increasingly valuable.

Owning or closely controlling the financial infrastructure can mean greater flexibility, improved economics and the ability to build more products around an existing customer base.

The result could be a more vertically integrated fintech sector, where the biggest players increasingly control everything from customer-facing apps to the institutions that hold and move their money.

The question now is whether this model will remain concentrated among Nigeria's biggest fintechs or eventually become the standard path for companies looking to operate at significant scale.
