The ideal size for Mattermost Team Edition is up to 50 users, and the system probably continues to work fine up to a couple of hundred.
As deployments near or exceed this milestone, our intention is for Mattermost champions to find the right capabilities in the commercial versions in order to developer a business case for purchase, to bring on the commercial capabilities and to scale smoothly and reliably.
Custom groups helps our champions build a strong business case for joining our commercial community.
You can learn more about our commercial versions at
https://docs.mattermost.com/about/editions-and-offerings.html
There’s also guidance in the docs for contacting the Mattermost customer teams who can support our champions in making the business case to their organizations.
Thanks for asking @lpnc_it. Does this help answer your question?
