I live in Austria, founded (and sold) a company years ago and have invested in 2 startups (6 figure each) - and I believe this is a misleading PR article. Austria has lackluster, under-funded universities, unattractive tax rules for companies and higher-paid employees and the country is dropping in most competitiveness, growth rankings that matter for startups. Infrastructure is good, but hiring good developers e.g. is very difficult because salaries are both low and burdened with high taxation, so they look elsewhere.

Personally, I wouldn't found another company in Austria. There are many better places in the EU, Ireland is probably the best option right now.
