I know someone that work in a startup that does exactly that. Opening a new country takes 3/6 months, as you need to open an office in the country and recruit people here. And that's now that they have a good process for it. Translation and localisation add processes and takes time. You need a new sales team for each country. Sometimes support too. Launching something in the USA would be equivalent to have France, Germany, Italy, Spain and the UK at the same time. That's a lot.
