I had the same experience at Citibank. We started at a small branch in downtown LA with our Series Seed round check for $3M. Even then we barely got any attention, and dealt with just a local branch manager. Later we closed $7.5M, still no attention; except this time due to consolidation we were kicked to a regional team that handled our account as a team. In fact we never had a dedicated banker, we were just handled like so many SMB by calling a banking center. Over the years we asked for things like corporate credit cards and the like, but it always seemed we were just a little too small (I guess with Fortune 50 clients, we were small to them). Anyway we eventually moved to a smaller independent bank for different reasons.
