But in general, not really. I also just founded a GmbH in Germany, and the paperwork really isn't that crazy, and for the more complicated parts you'll generally will want to have a tax advisor you are going to have a long-term relationship with (rather than a one-off founding service). I considered using a founding service, but ultimately, most of the "hard parts" about the process is in understanding what agency you have to talk to for what parts, which you'll have to learn anyways if you want to run a business in a way that doesn't land you in jail, so the benefits of such a service are marginal.
The only real way to streamline it would be to deregulate the process (e.g. getting rid of notary requirement).
