The problem isn't that you're too busy

I found that this has been the case with all companies I worked where the founders where still high up on the totem pole but not big enough to have an external board or hire experienced managers.

I have a few pet theories

1. Survivor ship bias - only control-freaks last long enough to grow this size (let's say 10+ people working for you)

2. Once you have enough on your plate that you can't keep track of all areas of your company, you grow wary and feel the need to butt-in

3. This is cultural - low trust cultures foster control freaks

Worth reading this gem from 2010 too:
