"Over the last decade, the maturation of the business landscape has opened new opportunities in Africa, especially the entry of accelerator and incubator programs (AIPs). These AIPs are consistently adapting their models to respond to the ever-changing needs of the ventures they support, and there is a need for existing literature to keep abreast with this dynamism in order to strengthen programming and the ecosystems in which AIPs operate. This knowledge brief explores characteristics of AIPs in East Africa, focusing specifically on Kenya, Uganda, and Tanzania. It highlights existing practices and perceptions among AIPs to better establish a common understanding of the current AIP landscape, best practices, and key challenges."
