Jamii.one is developing a digital platform to enable unbanked people access to the financial system. In low-income communities, a popular and established method of saving up is to join a savings group where you save up as a community rather than individually. Our app is built to digitalise and support these groups. Group members can use our app to record their savings and lending history, which creates a unique credit score. This credit score enables our users to gain access to financial services that they have previously been excluded from. The groups also learn business skills and how to use technology, empowering them to improve their future. Our app is co-created with more than 600 people in savings groups, basing the solution on their needs and abilities. They define the structure; we provide the tech and build the bridge between up to 1 billion people and the financial system.
