I don’t know about pre revenue companies, but, if you have to be secure and compliant with regulations from day one, you’re not going to take a chance with having a bunch of devs setting up your infrastructure. My bias probably comes from working mostly with companies in highly regulated fields.

Besides, I’m assuming that the cost savings a small company can get from being billed under a much larger organization account would make up for it. That and having cheap shared netops support.
