In the third episode of the series, we discuss fintechs and their role in the advancement of the banking sector. Research shows that fintechs make up the fastest-growing start-up industry in Africa. Their rise is being fuelled by several trends, including increasing smartphone ownership, declining internet costs, and expanded network coverage, as well as a young, fast-growing, and rapidly urbanizing population. CNBC Africa's Fifi Peters speaks to Djiba Diallo, Senior Fintech Advisor at Ecobank; Itumeleng Moagi, Co-Founder, Growth Factor Technologies; and Kiiru Mohoya, Founder and CEO of Fingo Africa.
