Hubs are key actors in the evolving innovation ecosystem. COSTECH hosts within its premises one of Tanzania’s major hubs – Buni Hub. COSTECH’s vision is to transform Buni into a model ‘Hub of Hubs’, creating a central node that can offer support to other hubs, labs, and innovation spaces nationally. To aid COSTECH in achieving this vision, HDIF undertook a study of innovation spaces in Tanzania to gain a better understanding of their ambitions, the challenges they face, and to identify their support needs. This study was limited to organisations physically located in Tanzania, with face-to-face activities driving innovation in some way.
