Sou Sou was inspired by traditional village savings and loans models that exist around the world. In West Africa and the Caribbean, it is called susu. In South Korea, the term is gaedon. In the Middle East, it is called gameya. Millions of people - roughly 80% of the world's population, according to the World Bank - have been using informal savings and loan practices for centuries as a way to save and invest when banks and venture capital are not an option. We are modernizing this practice for the 21st-century borrower.
