- Spain has an entrepeneurship visa, that any founder from anywhere can apply for. To apply I think you need to produce a credible business plan which shows it'll employ a certain number of citizens (I don't know if EU or Spanish specifically) eventually.
- France similarly has an entrepeneurship visa for founders from anywhere. I believe one of the requirements is to raise a certain amount of seed from specifically French accredited investors.
But, while I think it's better than you're implying, I definitely agree with your general thrust that visas need to adapt to embrace the growing popularity of people moving country not necessarily for employment, but to create new companies, jobs and growth.
It's unnecessarily cumbersome to do that basically everywhere (particularly in strong economies) right now, not just the EU, and that's a net loss for the citizens of the respective countries.
