We actively work with folks on custom pricing that aligns with their needs, so would love to understand what model makes sense for you! If pricing is the blocker, you can email me at antony[at]retool[dot]com. Would love to help.
Unless companies have too much money to waste, it is hard for me to understand this per user pricing. You have to do the work the create the app, your data gets locked and you have got to pay per user as you scale. Are companies just have too much money or too inefficient?
