The Job Of A CEO Is To Hire The Very Best People 

That's about it!

Hiring the people who will make your company is 1/3rd of the job of a CEO.

What are the other two?

@fredwilson quotes someone here in this blogpost on what a CEO does

A CEO does only three things. Sets the overall vision and strategy of the company and communicates it to all stakeholders. Recruits, hires, and retains the very best talent for the company. Makes sure there is always enough cash in the bank.

And if you are a manager or a CEO of a relatively new/small business, everybody understands what a mountain of a task this becomes.

Getting unfiltered resumes and sifting through them in order to find that one brilliant engineer that your team can afford and who will fit right into the growing little sub culture of your team. That's a monumental task.

In a lot of ways, the job of attracting the right people for your teams becomes akin to attracting the customers. To get customers, you sell value. To get employees, you sell culture.

To get loving customers, you sell value. To get great employees, you sell culture.

Selling anything is hard, and culture being the ambivalent, hard to quantify jelly becomes super hard to sell.

In this case, gaining an insight into how hundreds of startups are approaching this problem is a good way to get a grip on the things you can change today.
