It's theoretically possible to structure a debt offering where the investor is paid out over time by the donations of other future donors. This is morally suspect though: since a non-profit doesn't generate positive financial returns, they're really robbing themselves in exchange for larger impact now. A better model might be the "for-profit charity" which seeks to generate a return but not an excessive one. This might attract investors who are seeking a reasonable (but smaller) market return along with social impact.
