Ownership and Usage Policy

The Sustainable Innovation Seed Accelerator Program 2025 is now accepting applications. This intensive 8-week accelerator is designed to support seed-stage startups that are building sustainability-driven solutions across Africa. Anchored in Nairobi, Kenya, the program forms part of the UNDP’s timbuktoo initiative, a bold effort to nurture entrepreneurial ecosystems and scale climate-smart innovation across the continent.

With a focus on sectors critical to Africa’s future—agriculture, mobility, the built environment, and energy—the program is tailored for founders developing technology-enabled approaches that combine commercial viability with environmental and social impact. It is a platform for bold and visionary startups ready to scale their ideas and contribute to building more resilient, inclusive, and sustainable African economies.

About the Program

The accelerator combines in-person and hybrid learning (4 weeks in Nairobi + 4 weeks hybrid), hosted at the GreenTech Hub in Nairobi. Throughout the program, founders will refine their strategies, strengthen their technical capacity, and build networks that help them grow.

The approach is practical and hands-on:

• Mentorship: Learn directly from experienced sustainability and growth experts.

• Peer Learning: Collaborate with fellow founders tackling similar challenges across Africa.

• Ecosystem Access: Connect with investors, corporate partners, and policymakers to unlock opportunities for scale.

The goal is simple yet ambitious—to transform promising startups into scalable, sustainability-focused businesses capable of driving real change.

Who Should Apply

This accelerator is for entrepreneurs who are:

• At the seed stage, actively building solutions for the African market.

• Product-ready, having launched or recently introduced their innovations.

• Leveraging tech or tech-enabled business models.

• Motivated by a mission to create lasting social and environmental impact.

• Available to join the program in Nairobi for at least 4 weeks in person.
