Having founded a company in Germany, I would never under any circumstances do it again. Notaries should not exist, and could be replaced by a simple website. It's all incredibly tedious and slow, and there are lots of reoccurring work and fees. Closing a company takes 2-3 years too, even if there are no irregularities.
Germany loves endless bureaucratic paperwork which absolutely must be done in person (and good luck getting an appointment in Berlin), despite the many years of bleating about Digitalisierung which has apparently amounted to nothing.
It's our failed state, so what do you expect?
