Very small team so getting in is extremely difficult. Though as the company inevitably grows I'm certain more and more positions will open up.
At times in the office it was difficult to concentrate on the task at hand because there is simply a ton of distraction available to you- for the person who needs a quiet space away from the group, please be sure to mention this early on with the CEO and he will go out of his way to create a suitable area for you I have no doubt. For myself, it was a matter of putting on noise-cancelling headphones (JLab of course) and utilizing a tunnel vision mentality.
