We run two separate consumer brands under the same company, and customers of one have genuinely no idea the other even exists, which is exactly how we want it. Set up multibrand so each gets its own help center, its own support email, its own look entirely, but on our side it's still one team working from the same queue, nobody needed to learn two separate tools or switch logins depending on which brand a ticket came from. Reporting across both still rolls up into one dashboard too, so I'm not stitching together numbers from two disconnected accounts just to see the full picture.

Keeping triggers and automations consistent across both brands took more care than I expected, built a rule for one brand once and completely forgot to mirror it over to the other, which caused a small inconsistency in how tickets got auto tagged for a few weeks before I caught it.
