@dinos69 what do you mean by partnership?
Did you mean that the team should look for a partner?
I am confuse with your thoughts.
I doubt that they would be looking for a partner. Even with just a few developers handling the application, it would be difficult but possible. When the need arises, and when this application has emerged as one of the big applications, they would probably get another one.
The "partners" will be those developers creating the apps, and to some capacity the users as well. These are different relationships but I would think they all represent some kind of partnership.
