Three years ago, Puncha Maya, her husband and five children lived in a shaky flat in Southern Nepal.
Every morning, the parents walked the dirt roads seeking work in the rice fields.
After the harvest, the family went begging for food.
Today, the Mayas own a small paper-bag making company.
With the money they've earned, the Mayas have purchased a small plot, on which they grow vegetables and raise goats for additional income.
In fact, the family has saved $68.
This is remarkable in a country with an average annual income of $160.
Grace Mbakwa, her husband and eight children once lived hand-to-mouth in Cameroon.
Today, the Mbakwas run a clothing manufacturing business and own a home.
They are able to send their children to school, at a costly annual sum of $2 800.
The idea of starting her own business seemed impossible to Pilar Moya, a poor woman from Atahualpa high in Ecuador's Andes Mountains.
Today, however, she is one of the proud owners of a bakery specializing in sweet cakes.
These businesses are part of economic revolution sweeping the developing world.
The sponsor is the Trickle Up Program— a non-profit organization founded by New Yorkers Glen and Mildred Leet.
This organization offers people like the Mayas, the Mbakwas and Moyas modest $100 grants.
Since 1979, the program has helped over 130,000 of the world's neediest people in 90 countries win small life-saving victories over poverty.
And it has turned conventional thinking about foreign aid on its head.
