Based on this, I would think that giving entrepreneurs money isn't the only way to help them become successful. Most successful startups in the US(especially SV) rely on much more than just money to be successful. Those "old boy" networks, mentors, etc. all play a big role in building successful companies. So why not give stranded African entrepreneurs the same opportunity?
I'd be more than happy to make out a profit-sharing loan and nurture an entrepreneur who hasn't had the luxury to get an advanced education in some field.
Perhaps money isn't all they need...
Our concern with a profit-sharing model is that there seems to be no practical way to enforce truthful reporting and sharing of the profits. Relying on self-reporting alone would result in a system where honest people are penalized (by having to make payouts based on their honestly reported profits) and dishonest ones are rewarded. At best, it would degenerate into a simple handout program.
If we at Zidisha had a way to provide advice and contacts that are sufficiently localized as to be useful to the entrepreneurs, we certainly would do so. However, my experience is that Western business advice is useless or nearly so to most people surviving on a dollar or two per day in Africa or Asia. The best results I have seen come about when people are connected with resources in a market system, and allowed to decide for themselves how to leverage those resources.
It will definitely be a mission to get honest reporting done (as you will have to "yak shave" to get to that point).
The only method I could think around it, would be to assist an accounting startup and make the local entrepreneurs form a cooperative, so that their 'books' are in order.
I wish you guys all the best :)
