A couple of years ago I tried to create a platform to connect people to local communities. The twist was that each community had members that worked as buddies to help welcome and guide new members. I got 10s+ communities and members but since there was no business model associated and I needed to work, I couldn't kept it up. The website was https://tribalo.app.

From the few numbers I got, I figure out it help. Maybe one day I don't need to work and can focus on it again.
