Germany is your problem. If you’re open to looking outside Germany, there are many options. You can open a U.K. company same day, an Estonian company with e-residency in a couple of days. Germany is uniquely nightmarish.

The problem isn’t incorporation - it’s having accountants in your jurisdiction familiar with the structure. You can incorporate in the UK for £50 instantly but you might have trouble finding an accountant in Italy that is willing to sort your accounts out.

It's not EU wide but in France we have Legalplace (https://www.legalplace.fr/) to create a company online quickly.
