We started out by questioning the way things are done and being single-minded in our determination to improve them. Everything we do is driven by a simple yet powerful belief that everyone in Africa has the right to be connected. Over the last decade, this vision has helped us change the face of communications in the region.

Our future-focused approach to new product development makes our services enduringly adaptable.

Our flexible and dynamic business model keeps us at the forefront of telecoms innovation. And by listening to customers, we ensure that our solutions are constantly evolving to meet their needs. In June 2017, Liquid Telecom raised $700m in a bond and term-loan issue that will help Liquid Telecom refinance debt and provide a war chest for further acquisitions.
