Einundzwanzig
Meetup / education networkThe German-speaking world's bitcoin community, grown out of the Einundzwanzig podcast since 2020 into roughly 200 local meetups across Germany, Austria, Switzerland, and neighboring countries. Each meetup is independently organized — no company, no headquarters — coordinated through a shared portal. One of the strongest examples of a meetup network that outgrew its founding media brand.
