Fire them fast. However, I wouldn't go that far to say Company is a goner. That depends on quickly the founders and management team fixes the mistakes. The thing is that company may not die (mine didn't) but it wont grow fast if you dont have the right team at the minimum.
You mentioned you are not the founder or have decision making power. In that case, you need to see what the founder(s) feel. If they are ok with mediocrity, it will creep in further. I always say that the team's urgency by default is always 0.5x of the founders. So if the founders themselves are relaxed, it will get worse.
