Have you hired a dedicated community manager to grow your audience?

Hi Hackers,

I'm thinking about starting my own agency that will be focused entirely on community management and growing the customer's audience. Not the classic SMM or email marketing, but managing chats and engaging audience in different communication channels.

My only concern is that the community management has no direct relation to sales. And you can't set up any KPI's related to money/revenue. That's why a business might think that community management is useless, which will cause false expectations and conflicts between the business and agency.

So the question is: have you hired a dedicated community manager? What was the motivation, KPI's and were you satisfied with the results?
