Compartmentalization addresses scaling. In particular, it addresses scaling group interaction between the members of a group with a common group goal but heterogeneous skills, responsibilities, and individual goals. It can address this problem well or poorly, but all the good solutions (and probably all the solutions) involve some amount of compartmentalization, and allowances for cross-compartment interactions. The really good solutions don't have huge downsides, but they all have costs. And there are tons of ways to do it wrong. If you are a small start-up, you do not have this scaling issue yet. You shouldn't bring in the solution if you don't yet have the problem, especially because the solution is costly, treacherous, and difficult to do well.
