In Their Own Words

ImpactMatters connects smart givers to high impact nonprofits, helping both do more good. In November 2018, ImpactMatters is introducing Guided Impact Reporting (G.I.R.), a free web app that guides nonprofits to quantify impact. The app walks the nonprofit through a structured set of questions and requires only data readily at hand. With a click, G.I.R. generates an estimate of cost-effectiveness, helping donors and nonprofits of all sizes make better decisions.
