Carbon Microfinance Bank Limited
Carbon is a Nigerian digital bank that lends people money and lets them pay bills, save, and move cash through a phone app.
Carbon is a digital bank in Nigeria. It gives people an app on their phone to do the everyday money things a bank branch used to handle: send and receive money, pay bills, and put a little aside as savings. But the heart of the business is lending. Carbon's big product is quick, small loans that people can get without filling out a pile of paperwork or visiting a branch.
Here's the simple problem it solves. In Nigeria, millions of people have a phone but not much access to a traditional bank, and even people with accounts often struggle to get a small, short-term loan when they need one. Carbon uses the data it collects from customers to decide, in minutes, whether to lend them money and how much. The borrower repays over a few weeks or months, and Carbon earns interest and fees on each loan. That lending engine is what pays the bills, while the app keeps customers coming back. The basic idea is like a neighborhood lender who knows you well. The more you borrow and repay on time, the more Carbon trusts you, and the bigger your next loan can be. That trust is the real product. It is also the company's biggest risk. Lending to people with thin credit histories means some loans go bad, and Carbon has to keep a close eye on who it lends to so the losses don't swallow the profits.
Carbon started life known as OneFi and rebranded as Carbon, and it has expanded beyond Nigeria into other African markets while building out savings and payment features around its core loan business. The hard part of this business is not the app; it's the judgment about who will pay you back. That's what separates a digital lender that lasts from one that blows up.
