In my twenties I worked for a "company" in Mexico that was the official QNX ditribuitor for Mexico and LatAm.
I guess the only reason was that Mexico City's Metro used QNX, and every year they bought a new license, I don't know why.
We also did a couple of sales in Colombia I think, but was a complete shit show. We really just sent them the software by mail, and they had all sorts of issues getting it out of customs.
I did get to go to a QNX training in Canada, which was really cool.
Never got to use it though.
