At least for me, there are 2 main problems: taxes and language. Taxes: here in Germany you pay 19% VAT on all transactions. Then, income tax, which quickly reaches 42%, then solidarity tax, basically almost half of your earnings evaporate Language: it's tough to address a decently large market, the biggest market (German speaking) is about 100M people, that's 4 times less than the USA market You can easily see that those 2 points quickly add up and create "corollary" problems. With those taxes + social security, to give a strong employee a strong salary you go towards a cost of +150k. To pay that much to employees you would need a big market to address to get revenues, but the market is small-ish, or you might look for VC money, but people with money are too scattered across too many languages and countries.
