Ask HN: Third world country, Internet company success stories?

I'm a CS student living in a third world country, and I am starting a Internet company in October.

I was curious to know about other successful Internet companies in third world or developing countries. There for I could use their experience.

Here in third world countries we have quite different problems. For example we don't have that many Internet users.

EDIT: I have read lots of PG's essays but little info there are applicable in my country. Like we don't have angles or VCs here.
