Wikipedia tells me that Bolivia has a GDP (PPP) of $89.018 billion, and there are a bunch of countries like Bolivia.
For all that people sometimes go on about untapped market potential in poor countries, it really isn't that easy when >90% of the population lives on less than 350 USD/month.
Sauce: spent the first 1/4 of century of my life living in a third world shithole.
On the other hand, Coca-Cola has a presence in Bolivia, and apparently controls about 60% of the Bolivian market.
With 11 million people, that's gotta be a nice piece of change.
If what you're selling is closer in price to a Coke than a Lambo, you probably shouldn't write Bolivia off.
If what you're selling is BOTH:
a) closer in price to a Coke than a Lambo
and
b) closer in demand to a Coke than a Lambo
Then, sure, you shouldn't write it off.
However, if you're selling stock-trading software, even for the price of a coke, you might not make enough money back to justify supporting Bolivia.
Cokes, even in poor countries, are still purchased by tens of millions of people at least once a month. Selling a similarly priced item that may be purchased by a few hundred people at most is not the same thing as Coke.
