Any Slack Growth Hacking Channel Recommendation?

My team and I just started using Slack, and was able to noticed how great avenue it is to connect more to other brands within (and outside) our industry. It also helped us discover many other digital strategies that many other businesses was able to do.

The question now is, how can we get more growth-hacking slack channels? Do you have any recommendations or link invites?

If yes, drop them down below! :)
