unfortunately it won't work without the APIs because it needs to be part of our product and there the data is constantly being updated dynamically by different actors / processes .
Hey Matt, I can't develop cool looking apps like this. I'm envious.
What I can tell you is that sales people at big software companies never say 'No it can't do that' as an initial conversation. They would say something like, 'I'm sure it could do that. Let's set up a call to get your requirements straight'. He might only need a subset of your features, and the api needed could be trivial. He might have a $moneyisnoobject Corp waiting to pay.
I mean you are completely within your rights to push away non-core users if you want.... but you know when a saas price page has Free, Basic and Enterprise teirs, and the Enterprise one has 'please call' next to it? That is because the price for customization is too embarrassing for both parties to make public!
