Frequently Asked Questions

Our Evolution

The idea for S3IDF emerged from a shared frustration that conventional approaches to solvingdevelopment challenges were not addressing problems holistically and that even well-intentioned programs often bypassed the poor. As a result, in 2001 we began ourProjects &Programs and Advisory Services to prove that market-based approaches could improve livesand livelihoods for underserved communities. On the forefront of the market-systems approachmovement, we’ve demonstrated that programs can be inclusive, equitable and effective at anysize, especially the micro-and small-scale.


Recognizing similar challenges in the impact investing space, we’ve expanded our focus toinclude designing smaller-scale, high-risk, impact oriented investments that will balancetheinvestment continuum and propel the sector forward
