Activity Description: S3IDF brings to small scale, pro-poor infrastructure business opportunities, the innovative financial, institutional and technical engineering that is common in large infrastructure deals. To do this, S3IDF operates as a "social merchant bank" targeting very small enterprises. With help from S3IDF, the financing barriers that poor people in developing countries face for infrastructure investments can be overcome and S3IDF's participation can be leveraged by helping to access financing from local banks or other local sources.
