Sustainable Innovation Seed Accelerator Program 2025 for seed-stage startups 

The Sustainable Innovation Seed Accelerator is an 8-week program for seed-stage startups building solutions across Africa. Based in Nairobi this program is part of UNDP’s timbuktoo initiative, and is designed for founders developing technology-enabled approaches in agriculture, mobility, the built environment, and energy. The program is looking for bold, sustainability-driven companies ready to scale their vision and drive change.
