True, from what I've seen the threshold lies somewhere at 10-12 people, assuming a mixed team engineering + marketing + etc.

But while you are small you can take advantage, remove all formalities and be in-place as much as possible. You can move so much faster, having trivial respect and ethics in mind, as in don't talk loudly about sales just next to an engineer who seems to be working on something. And vice versa.
