Asia, some parts of Africa and some parts of the Middle east are now some what ripe for investment as far as tech startups go, the barrier of entry for learning development has been lowered sufficiently and education in some places is actually quite available and well established these days.

These aren't regions in which you need to have multiple series of funding and raise millions to be able to pull even a power point presentation of the ground. Places like Cairo which have quite good higher education can be considerably cheaper than the baltic states and eastern europe were 5-8 years ago and if you develop a non-regional product you can have a huge return on investment, and it also allows companies to become cash flow positive very quickly as their yearly burn rate is probably lower than the price of some investor relation event/party in SV.
