There is a job at Amazon that is highly coveted throughout the company and that nearly anyone in business would kill for. The man holding this job—and they have all been men so far—has had direct, almost unlimited access to Jeff Bezos for as long as two years. He follows Bezos around, travels with him, sits in on his meetings, and confers with him at the end of many workdays. The job title is unofficially the “shadow” to the CEO, or more formally, the technical assistant or technical adviser. I blogged about Bezos’s League of Shadows today on Businessweek.com.
