Ask HN: What’s your experience founding and managing a EU business?

According to a subjective review of Doing Business filtered by OECD High Income countries and ordered by Ease of Doing Business Rank [0], the most business-friendly countries would be Denmark, the United Kingdom, Norway, Sweden, Estonia, Finland, Ireland.

(Denmark, Norway, Sweden, Finland all require nontrivial paid-in minimum capital.)

What are HN experiences with founding and managing a small, limited liability business in a EU country? Despite its favorable ranking, does the UK need special consideration due to the upcoming withdrawal from the EU?
