Henddu

Henddu is a France-based deeptech startup that develops smart air quality observatories tailored for African cities. By leveraging a digital platform powered by proprietary algorithms, Henddu offers a cost-effective solution—up to 6 times cheaper in capital expenditure and 10 times in operating costs than traditional systems. The platform integrates diverse data sources including satellite Earth observation, ground sensors, meteorology, and health indicators to provide real-time environmental intelligence. Its space-based data fusion, using services like Sentinel and CAMS, enables hyperlocal pollution forecasting (HOQA), hotspot detection (Henddu-Spot), and vulnerability mapping (Henddu-Cluster). This multidimensional approach strengthens public policy, institutional capacity, and community engagement through actionable, data-driven insights. Henddu empowers governments and industries to shift from passive monitoring to predictive and strategic environmental governance—driven by both space and ground intelligence.
