Are you considering any companies as partners? I didn't fully understand how much your project is autonomous while working with social media users.
We are going to be fully independend on first steps. Our social networks code analisys shows that there is no need to use any special integration. Every user has unique id and it's enough. All html/css code modifications for our system our plugin can make "on the fly". As a result you will be able to distinguish our users' pages simply.
In this case, your project will be able to get a great profit without the participation of partners. I think the sale of ICO is very suitable for independent projects.
