After eight years of running Loudcloud and Opsware, I had learned so many hard lessons that building the team was easy. I understood the importance of hiring for strength rather than for lack of weakness, and I understood the meaning of “fit.” There are lots of smart people in the world, but smart is not good enough. I needed people who were great where I needed greatness. I needed people who really wanted to do the jobs they were hired for. And I needed people who believed in the mission—to make Silicon Valley a better place to build a company.
