You have banks as customers but only $4k MRR?! Something is going wrong here. Where's patio11 to tell you to raise prices.
Maybe the enterprise plan isn't aggressively enough priced, or aggressively enough differentiated..?
And by "bank" I mean "credit union".
That or the Enterprise customers have some sort of extended free trial thing going on.
And by "one from North Dakota" he means "only in departament of immigration" of them.
