Evidence you can act on. Impact you can measure.
The Institute for Development Impact (I4DI) is a think + do tank working at the intersection of social and environmental impact. We blend the strategic analysis and evidence generation of a think tank with the hands-on implementation and problem solving of a delivery partner. This means we connect research and evaluation to real-world practice, working alongside our partners to design, test, and scale solutions grounded in rigorous evidence, powered by technology, and tailored to the communities we serve.
We work differently: through genuine partnership, world-class expertise, and a level of service that matches the complexity of the challenges we tackle. Above all, we stay relentlessly focused on moving the needle for people, planet, and our purpose-driven partners.
