I am currently trying to estimate how many internal system administrators our startup needs as we scale up. I know this depends on a ton of factors, but I would like to see some comparison numbers.

Our specs:

- 240 people, ca. 30% engineers, 30% artists, rest misc

- On average 12 people starting per month

- 60% iMac and MacBooks, 30% Thinkpads, 10% desktops

- Internal IT tasks: onboard new hires, keep existing computers running, internal office networking, some general maintenance (coffee machines). No servers in the office, no devops etc., purely office infrastructure.

We currently have one experienced admin, one junior admin and one handyman (half-time).

It would be great if you could share your "specs"!
