Database of 300k communities

Hey,
-> We built this: https://thecommunityatlas.com/en/

We aggregate engagement data on 300k communities on 68000 topics.
We rank them by online, offline and general engagement.

-> Play with it here: https://app.thecommunityatlas.com/

Write me here if you want a full access.

We tried several things but haven't found the right Product market Fit for now

What do you think could be a good business model for it?
What other features would you like?

(We are adding a feature to message communities directly from the application)
