For millions of Nigerians, an OTP is just a six-digit code that arrives on a phone when they are trying to complete a transaction.

But behind that seemingly simple message is a complicated infrastructure problem.

A bank customer trying to transfer money, a fintech user logging into an account or a merchant waiting for a payment confirmation may have only a few seconds of patience when an OTP fails to arrive. The customer rarely thinks about the network, messaging routes or the infrastructure responsible for delivering the message.

They blame the bank.

That invisible problem has become the foundation of a Lagos technology company that has spent the past nine years building infrastructure around one of the most easily overlooked parts of Africa’s digital economy.
