Shyam Sankar is Palantir's chief technology officer and the man most responsible for making its business and technology work. He joined in 2006 as employee #13, when Palantir was one of Silicon Valley’s freakshows: a small and somewhat demented chickenhawk of a startup with a buggy demo and no customers. For 20 years, largely from the shadows, he has brute forced it into the spearhead of "defense tech" and a $320 billion company. He embedded with intelligence analysts in Virginia, special operators in Iraq and Afghanistan, and on the factory floors of some of the world’s biggest companies—building and rebuilding software in the field, sometimes with phones taped to his head so he could give and take feedback while keeping his hands free to code. He invented the “Forward Deployed Engineer,” which has since become the object of both skepticism and imitation. Alex Karp, Palantir's mercurial co-founder and CEO, says the company would not exist without him. The same can be said of the modern defense tech industry, many of whose founders cut their teeth working for Shyam. In this deeply reported profile, @JeremySternLA tells the story of the most pivotal but hidden figure behind America’s most controversial company. He also gives the clearest explanation you'll read of what Palantir actually does, whether its valuation is justified or absurd, and what any of this has to do with the company’s mission to save Western civilization. It begins in the Grand Ballroom of The Pierre hotel and winds through Nigeria and India, Florida and California, Iraq and Afghanistan. It ends with a rabbi, a monkey, and a lesson in what it means to buy time in the face of a coming fire. Only in Colossus:
