Financial Technologies (fintechs) have experienced an expansive growth in many sectors over the last decade as a result of their dynamic business models which provide many unparalleled alternative and complimentary services to those that are being provided by the traditional financial institutions. Their proclivity towards affordability, accessibility, security, and better customer experience has the prospect of broadening the horizons of financial inclusion to incorporate many people who were excluded or underserved in the traditional financial system. Financial exclusion has been much prevalent in developing countries where the traditional financial systems have not adequately met the needs of the masses. Moving from this premise, this thesis seek to investigate the impacts of fintech innovations on financial inclusion in developing countries and the challenges they face together with a case study on mobile money in Sierra Leone.
