Jim Whitehurst joined Red Hat in 2008, as its valuation rose past $10 billion and the company entered the S&P 500. He believes that leaders should engage people, and then provide context for self-organizing, and in 2015 even published The Open Organization: Igniting Passion and Performance (donating all proceeds to the Electronic Frontier Foundation). The book describes a post-bureaucratic world of community-centric companies led with transparency and collaboration, with chapters on igniting passion, building engagement, and choosing meritocracy over democracy. 
Jim's argued that Red Hat exemplifies "digital disruption," and recently predicted a world of open source infrastructure running proprietary business software. Fortune has already called Red Hat "one of the geekiest firms in the business," and their open source cloud computing platform OpenStack now competes directly with Amazon Web Services. Red Hat also sponsors the Fedora Project and works with the One Laptop Per Child initiative.
