This is an excellent read on the considerations one needs to make when scaling a startup.
Understanding the Laws of Startup Physics starts by understanding that people grow linearly while fast growing scale ups grow exponentially.
It is people who are in the way and slow things down and the key lies in having the right people with the right mindsets in the right place at any given time.
A natural and carefully considered churn in executives is essential and offers a great opportunity for incumbents to recruit from fast growing startups.

Great read with tons of lessons.
