This seems to be a professional chat client, so think Microsoft Teams and not Discord. Though they do have a blog post about why people prefer to use Pumble over Discord which is interesting. I don't think Discord when I think of teams so it's kind of odd they compared their platform to Discord lol. Anyways, I don't think most people here will use this one unless you manage a group of people and you need something more professional and don't use Teams. They do allow importing from Slack so if you're using Slack and want to try an alternative Pumble might be a good replacement.
