and can easily be integrated to our current working concept.
Sure, let us all know how that works out for you.
To anyone actually considering and capable of undertaking this project, I'd offer the following.
A membership site requires an adult designer (3-4k) and a custom CMS (2-4k), a membership management script capable of taking Bitcoin (1k if hardened). It makes no sense to offer shares (recurring income) for a one time expense.
If you build a site, it will then be on the radar of the large players- that's where they look. They think it terms of competing websites- not competing apps. So you've just substantially shortened your lead by announcing that your business model will work on their websites just fine. So their coders will get cracking. This website won't get any traffic without an affiliate program, that cuts into profits and requires a large advertising budget to get the word out to potential affiliates (1k month).
This is one of the problems with businesses started with outside capital- it's easy to spend other peoples money. If it was their own money the developers would come up with something simple and clever, if they have funding- lets have a money fight. If they don't get sacks of money, they claim they can't start anything because no one will fund them.
A simple App website advertising it's functionality (if you use the same UI designer as the app it saves money), and providing a Market link is sufficient. Ideally it's creation would be paid for by income generated from just the initial Android app. Done properly it requires more skill and planning than it does capital. The other guys always have more capital so it's a lousy tool to try and compete with.
All you need is a mobile app programmer, a lawyer and probably a UI designer- the latter two are a one time expense. There's really no need management or any additional staff beyond a single developer/owner. No one else is needed and they will just cannibalize profits and hurt growth. There is no reason this can't be bootstrapped by a single developer. The other skills required are modest, one time expenses.
