Information about our platform partnerships program can be found here and you can contact the partners team through the "Contact" link on that page. You should start there to establish how your app will fit on the platform --- who will use it, what product(s) will it integrate with, how will it be marketed, sold, etc. Then your developers can come back here when you start working on your app, with all their questions. Thank you for your interest.

Thanks Jonathan. I contacted the team on Sep 28, and haven't received the reply yet. Is there any specific person that I can talk with?
