You can almost never win this situation, I have seen funded startups literally go under because of friendships and incorrect attribution of who did what.

Ah, the true sign of a "team" - credit being apportioned...

The problem isn't one person being over looked, it's that one person is being praised.

We all make contributions that we feel are noteworthy, but when someone else's noteworthy contributions are highlighted we then have to ask, why theirs and not ours.
