Investing in the stock market is far more common in the US compared to the EU for the average person (something like 60% versus 15% of people in the EU). I imagine that has a huge impact on the amount of money sloshing around to fund companies from the top down.
The EU is bigger than the US in population terms, but when it comes to raising funding for a new startup it’s hard to look far beyond the borders of your own small country for many reasons. If this could be fixed it would make a massive difference in my view.
I’ve been involved in the founding of a few companies in Ireland and raising funding is tough and for all the work the figures are tiny compared to the US. You’ll likely be talking to Irish and UK investors only.
