Development Impact Group

We build public-good AI systems for development: evidence tools, crisis early-warning dashboards, domain-specific models, and curated datasets. 

ZeroHungerAI (public dashboard launching 2026). Real-time, district-level food crisis early warning system powered by news streams, covering 82 IDA countries with weekly updates. 

HateDay (2026). First global hate-speech dataset representative of a single day on Twitter, covering eight languages and four English-speaking countries.

ImpactAI (public launch October 2025). Conversational AI agent that synthesizes thousands of rigorous causal studies, giving policymakers instant access to high-quality development evidence with full source attribution and standardized comparisons across interventions. (Visit, Learn more, Demo) 

NaijaXLM-T (2024). Context-specific large language model for hate speech detection in Nigerian online contexts. Achieves 90% accuracy versus 60% for generic frontier models. (GitHub, Hugging Face)
