Does your company run a community on any platform?

No, at this time, I do not mean social media but something like an enclosed community for the core (top-tier customers).

On Friday, I had a call with a marketing manager at @Crisp and he mentioned this thing.
I know there are more companies that are trying to create more personal connections with paying clients and network among themselves. I love community management, wanna learn from the best and apply the best practices.

Just out of curiosity:

• Does your company host any community for paid clients? (Or are you a part of it?)

• How do you treat people inside it? (perks, benefits, things you discuss there, channels)

• What platform did you choose for hosting it?
