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...
