Really liked this story on Mark Z at Facebook. A great model for Entrepreneurs. The notion that as a company scales, so must the leadership. They either need to grow as quick as the business or grow elsewhere.

“Every six months, he can upgrade every role in the company,” said one employee about Zuckerberg, requesting anonymity. “That’s true for Gideon Yu, it’s even true for [COO Sheryl] Sandberg.”

The idea of growing at the same pace – or preferably faster pace, than the company is a powerful one.
