A market for impact ImpactMatters connects smart givers to high impact nonprofits, helping both do more good. Donors want to give to nonprofits that share their values. And they need to gain confidence their dollars are put to good use. ImpactMatters is the platform where donors can give based on evidence of impact. How it works Nonprofits register on ImpactMatters and go through a free, guided process to quantify their impact. With those numbers in hand, ImpactMatters can show donors the exact data they need, but cannot easily find elsewhere: Is this nonprofit doing a good job at helping people? Donors can find nonprofits that match their interests — and then get an instant snapshot of what their dollars buy.
