I am happy to reveal that a non-profit legal entity for Mastodon, Mastodon gGmbH, is in the process of being entered into the German company register.
For context, I have been operating as a sole proprietor so far.
It's been in the works for 8 months but I didn't want to announce anything until everything was finalized just in case it didn't work out. Yesterday, I paid in the starting capital.
It wouldn't be possible without the help and advice of @mellifluousbox. More to follow in blog form.
