Modest Needs

Modest Needs was conceived, built and still operates on simple concept — a small investment to help an individual or a family with a utility bill, rent check or health-care invoice reaps huge rewards if it keeps its recipient employed or prevents an eviction.
So Modest Needs cuts small checks to people in short-term straits. The goal is to keep the recipient self-sufficient and off public assistance.
The average Modest Needs grant is $180, and the organization won't give any single applicant more than $1,000. But Taylor estimates that the $234,000 Modest Needs has given out since its inception has saved its recipient families about $7.7 million in possible lost income.

socialmarkets

Socialmarkets is a big idea, and deserves a fair amount of elbow room to describe. Reduced to its simplest terms, socialmarkets is a site which selectively applies the market model to the social sector, and supports the web-based community around that application. We would like to fill in some of the larger holes left in the socialmarkets fabric by such simplicity.
For starters, there is our vision of an ideal outcome of the socialmarkets enterprise: the foundation of a true social capital marketplace. We believe such an outcome is only possible through the measurement of both social good and the risk involved in its creation. We know that such an outcome is only possible with the cooperation of both those who create social good and those who invest in them.
