but there is a reason that a significant proportion of the startups in Germany were UK Ltds until Brexit cooled that down. I don't take it as a positive sign for the process that people will literally use another country's registration process because the home one is so bad.
The reason was that the GmbH required depositing 25k. But the UG already solved that problem and afterwards the UK Ldt didn't really make sense anymore.
We had some investors refuse to invest in us as a German company because it was just too much hassle, and not worth the cost if they made a relatively small 10k€ investment.
UK Ltd much easier to invest into.
In the end it comes down to cost of business. If the German market is interessting enough, a GmbH is just one thing to do. If it is not, pick another EU country.
