Our Story:

Across Africa, payments are more than transactions. They are gateways to prosperity, connecting people, businesses and communities to opportunities and growth.

Through trusted technology and customer-centric innovation, we build connections that inspire progress, strengthen economies and transform payments into a tool for progress.

Since our founding in 2003, we've continuously adapted and grown, leveraging our experiences to simplify payments for businesses. We are driven by an unshakable belief that seamless people-centred payments are the key to unlocking prosperity.

Today, Cellulant powers online and offline payment processing, allowing businesses to collect payments, send payouts, and accelerate business growth.
