About ERI Institute
Founded in 2014 by Gilad Tanay, ERI is a social impact research and consultancy firm that brings together a team of data scientists, systems thinkers, and experienced social impact specialists. We work with investors, philanthropists, and public sector organizations to help them maximize their impact. From the beginning, one question has driven everything we do:
How can we create value for those who are genuinely working to make the world more just and equitable?
To answer that, we developed a unique approach. One that combines rigorous data science with systems thinking and strategic insight. Our mission is to equip changemakers with the evidence and intelligence they need to amplify their impact and drive system-level change.
