Pumble is a free team alternative to Slack and Microsoft Teams. Unlimited users and history - all for free.
Collaborate on Pumble - It's FREEInvite your whole team and collaborate together.
Very similar to Slack, only with more free features (primarily, access to entire history and group calls).
Easier to use than Microsoft Teams, quicker to set up, and more free features in the basic version.
Just as awesome, but unlike Discord, Pumble is oriented towards teams and businesses.
