Hi Ibrahim,
you ask sensible questions, also in your previous ost.
Although these questions require more than a written answer on a forum. Also question like revenue is not something you will find by asking the community.
I think the information on this page will help you a lot: https://www.mendix.com/evaluation-guide/
Also, are you a interested MX platform user/customer or Mendix partner?
Depending on this I advise you to reach out to Mendix and have a conversation with their partner/customer team.
Answering a bit from my point of view
