- A printer (the most important equipment of any German startup founder)
- Envelopes for letters
- A stamp with your company name (some companies and agencies you deal with require you to stamp things, because a stamp obviously proves, beyond any doubt, that you are acting on behalf of your company, because obviously no one would be able to create a similar stamp with your company's name on it, right)
- A virtual office address at a coworking space (because you're receiving physical mail, and also there are weird tax reasons not to register your company at your home address)
- A mail-scanning service (because you don't want to walk to the coworking space every few days to pick up your physical mail)
- A mail-forwarding service (so that the mail gets forwarded from your virtual office address, which now has exactly no purpose at all, to your mail-scanning service)
