From a good idea, Zindi has grown into an engine for putting untapped data science talent to work across borders and across sectors. The 25 000-strong Zindi data science community has, over the last 2 years, produced remarkable machine learning solutions to real African problems, proving the power of African talent to change the world. In this presentation, we will talk about how Zindi-curated models have had an impact in fields as diverse as logistics, agriculture, health, climate change, and finance, and how the platform is building and growing into a world class community of practice in data science.
