Their brand-new two- or three-person start-ups are given a seemingly impossible challenge: to turn a raw idea into a viable business, fast.   Each YC session culminates in a demo day, when investors and venture capitalists flock to hear pitches from the new graduates. Any one of them might turn out to be the next Dropbox (class of 2007, now valued at $5 billion) or Airbnb (2009, $1.3 billion).   Randall Stross is the first journalist to have fly-on-the-wall access to Y Combinator. He tells the full story of how Paul Graham started this ultra exclusive institution, how it chooses among hundreds of aspiring Mark Zuckerbergs, and how it teaches them to go from concept to profitability in record time.

    Founded in 1926, McKinsey can lay claim to the following partial list of accomplishments: its consultants have ushered in waves of structural, financial, and technological change to the nation’s best organizations; they remapped the power structure within the White House; they even revo­lutionized business schools. In The New York Times bestseller The Firm, star financial journalist Duff McDonald shows just how, in becoming an indispensable part of decision making at the highest levels, McKinsey has done nothing less than set the course of American capitalism. But he also answers the question that’s on the mind of anyone who has ever heard the word McKinsey: Are they worth it? After all, just as McKinsey can be shown to have helped invent most of the tools of modern management, the company was also involved with a number of striking failures. Its consultants were on the scene when General Motors drove itself into the ground, and they were K-Mart’s advisers when the retailer tumbled into disarray. They played a critical role in building the bomb known as Enron. McDonald is one of the few journalists to have not only parsed the record but also penetrated the culture of McKinsey itself. His access puts him in a unique position to demonstrate when it is worth hiring these gurus—and when they’re full of smoke.
