Sustainable Innovation Seed Accelerator

History and Founding Story

The Sustainable Innovation Seed Accelerator is a key initiative by 500 Global, a renowned venture capital firm and accelerator, in partnership with the United Nations Development Programme (UNDP). This collaboration is part of UNDP's broader Timbuktoo Initiative, which aims to foster innovation and entrepreneurship across Africa. The Nairobi-based program specifically operates as one of ten hubs within this initiative, focusing on supporting founders who are building sustainable solutions. The program's inception reflects a shared commitment between 500 Global and UNDP to address critical challenges in Africa through technology-enabled innovation, particularly in sectors vital for a climate-resilient and inclusive future.

Mission and Values

The accelerator's mission is to identify, nurture, and scale seed-stage startups that are developing technology-enabled solutions for sustainable impact across Africa. It is deeply rooted in values of sustainability, innovation, and community building. The program champions founders who are not only building commercially viable businesses but are also driven by a mission to create positive environmental and social change. This commitment to impact is evident in its focus on sectors like agriculture, mobility, the built environment, and energy, which are crucial for Africa's sustainable development.

This extensive network is designed to support startups in expanding their product reach and customer base, providing crucial access to resources and strategic alliances.
