OUR STORY

Since our founding in 2003, Cellulant has evolved from a digital content provider into a leading payments platform with a presence in 35 African countries. For more than 20 years, we've built a robust network that integrates multiple payment methods, addressing the unique challenges of Africa’s diverse payment landscape.

We began selling ringtones as a digital content business and quickly realised the need for a more streamlined way to manage payments. This realisation led us to develop a platform that initially allowed customers to check their bank balances and eventually evolved into a comprehensive payment solution. Our journey has seen us partner with more than 1000 businesses, including some of the largest banks and mobile money providers on the continent.

Throughout the years, we've continuously adapted and grown, leveraging our experiences to simplify payments for businesses and consumers alike. Today, Cellulant powers online and offline payment processing allowing businesses to collect payments, send payouts, and accelerate business growth. We’re the payment fabric that makes interoperability possible and stitches Africa together for the global economy.

OUR VISION:

To enable seamless payments across Africa for businesses, banks and consumers.
