Google was growing fast, and the founders worried they’d divide into cliques and lose their cohesive culture. Stacy Sullivan, who had been hired in 1999 as the first employee in human resources, and Joan Braddi, Omid Kordestani’s trusted deputy, were asked to assemble a disparate group of early Googlers to devise a coherent mission statement of core principles the company could embrace. Twelve employees gathered in the cafe, each from a different department. The discussion went in circles for several hours, with Sullivan dutifully writing cliches on a whiteboard. Some wanted the group to enunciate a set of rules: Don’t mistreat people; Don’t be late; Don’t lose user focus; Play hard but keep the puck down. The engineers in the room weren’t interested in codified dos and don‘ts because they reeked of corporate America and offended their sense of efficiency. They also took too long to read. After hours of exasperating discussion, Paul Buchheit blurted, “All of these things can be covered by just saying ’Don’t be evil.”‘

Within a day, engineer Amit Patel, Google employee number 7, wrote the slogan in impeccable handwriting on whiteboards all over Google’s offices. The slogan became viral. When opposing an idea at internal meetings, Googlers would proclaim, “That could be evil.” The slogan became Google’s rallying cry, a way to distinguish itself from other corporations and Microsoft in particular, a way to harness the goodwill Google enjoyed as a free service bringing the world’s information to everyone’s fingertips. To former Intel chairman and CEO Andy Grove, the slogan was too vague to define a boundary, and smacked of self-righteousness. “Do you think Hitler thought he was evil?” Grove said he thought at the time. “It’s too vague, too self-serving, self-defining. ‘I’m not evil, therefore I’m not evil.’”

Eric Schmidt was happy with the slogan, though, and happy with what he was accomplishing at Google. Years later, he sat on one of three canvas-backed directors chairs jammed into the closet-sized conference room dubbed “the directors room” that is next to his office in Building 42. The view from a narrow vertical window overlooked a Google parking lot; the white brick wall to his left held a whiteboard containing mathematical formulas; to his right were several framed newspaper clippings, including one headlined “The Grown-Up at Google.” He admitted to feeling that he had grown as an executive since his days at Novell. “Most people who worked with me ten years ago,” Schmidt said, “would have said, ‘He’s smart, a nice guy, but he can’t lead.’ What is the distinction between then and now? Toughness.”

Back in 2001, his “toughness” was circumscribed. He did not issue orders to the founders, he had to persuade, to prioritize his concerns, and pick his battles. There were palpable tensions-the founders would sometimes loudly explode in meetings that the company was becoming bureaucratic, and Schmidt knew he was the target. These were three strangers working together, and the founders were uncomfortably ceding some management control over their invention, their baby. Schmidt knew the founders did not blame each other. There was rarely a hint of tension between Page and Brin-“In all the years I’ve worked with them,” said John Doerr, who is a Google director, “I’ve never seen them get angy with each other.” But it was not unusual, said another early investor, to witness emotional outbursts by the founders aimed at others, and to see these outbursts fielded and defused by the calm, self-effacing Schmidt. The go-slow, relaxed way that Schmidt approached the founders or changed the management meetings or eventually chased a squatter from his office was at times exasperating to others. While describing Schmidt as “the unsung hero” of Google, Shriram admits, “He had a slow start.” The founders at first, he said, “challenged everything,” and openly wondered: “Could they trust his judgment?” Meanwhile, the VCs were pushing for a revenue plan. And Moritz was skeptical that Schmidt was the right man to bully it through Google.

Schmidt needed help to lower the emotional temperature, and to upgrade Google’s management. That help came in the form of Bill Campbell, then sixty-one, a barrel-chested man known throughout Silicon Valley as “the coach.” At one time Columbia University ’s head football coach, Campbell had also been a senior executive at Apple and a CEO of several Valley companies, including the Go Corporation and Intuit, the now-thriving online software company that provides financial services to individuals and small businesses and where he worked side by side with the founder. John Doerr knew that Campbell felt an obligation to give back to a Silicon Valley that had made him rich enough to own his own Gulfstream IV His discretion is legendary, and part of his allure. Aside from a profile in the magazine of his alma mater, the only other time he has ever been profiled was in a superb 2008 Fortune magazine piece by Jennifer Reingold titled, “The Secret Coach.” His many friends offered tributes but Campbell would not sit for an interview. A Google search retrieves very few Campbell press mentions.

Doerr served on Campbell ’s Intuit board, and had called on him to mentor young leaders of Valley companies. Regularly, Campbell would join fifteen or so of Doerr’s dot-com CEO clients over dinner. The sessions are dubbed Camp Campbell, “and I’m not allowed to attend,” said Doerr, who described Campbell “as one of my two best friends.” In late summer of 2001, Doerr reached out to his friend to help Schmidt and the founders. “I felt it was an opportunity worth Bill’s time,” he said. “Eric had not been CEO on a scale Google would become. Larry and Sergey and Eric needed to be coached.”

In the Valley, Coach Campbell is a magnet for friends old and new. Still the chairman of Intuit, he is also the colead outside director at Apple, and one of Steve Jobs’s few confidants. On weekends and evenings, when big college or professional football and basketball games are televised, Campbell can often be found with a group of buddies in downtown Palo Alto ’s Old Pro sports bar, a Stanford student hangout he owns. He’ll have a table in the middle of the pub piled high with hamburgers, French fries, pizzas, and his preferred drink, Bud Lite. Just under six feet tall, Campbell is easily spotted, and not just by the Kennedyesque thatch of gray hair that sprawls across his forehead: he’s the guy in constant motion, moving about the room dispensing high fives, fist pumps, hugs, and baseball caps. He sports an oversized Columbia 1962 ring and weighs just three or four pounds more than he did as a college linebacker. At the Old Pro, he’s garrulous. Outside, he’s allergic to interviews with reporters, and even with friends he sequesters conversations he has with other intimates. His discretion is well known, and part of his allure.

In a rare 2007 interview with two McKinsey amp; Co’s partners for the McKinsey Quarterly, Campbell said something that is music to engineers at places like Google: “empowered engineers are the single most important thing that you can have in a company.” He was talking about a tech company, and he went on to say that to foster innovation “you’ve got to be careful that you don’t make engineers beholden to product-marketing people. For me, growth is the goal, and growth comes through having innovation. Innovation comes through having great engineers, not great product-marketing guys.” He also said that smart tech executives should spend entire days “doing nothing but reviewing projects. A whole day, with the whole management team, so that we can clean up those projects, clean out the ones that aren’t going to be good, and take the bodies that are recovered and put them on the projects that look like they have the best prospects.”

Explaining Campbell ’s role as a bridge builder at Google, Moritz said, “Bill’s contribution has been to take the emotion out of decisions. He’s more objective. He’s seen as a neutral source and a fair man.” The objectivity was needed, he explained, because: “You had two founders who were in their twenties and Eric was twenty years older, and you had to make that relationship work between people who did not know each other. It was natural that the founders would be suspicious. There were bumps at the beginning that Bill helped smooth over.” The biggest bumps, another Google insider said, were not between Schmidt and the founders, but with two venture capitalists on the board, Doerr and Moritz: “Eric had a busy-body board. The impression the board had was that Larry and Sergey were not focused. When they got Eric in, now they wanted to micromanage him.” They wanted Schmidt to push harder to monetize search. Doerr and Moritz “were both impatient,” said Shriram, who had served as a bridge between the founders and the board and gratefully handed this role to Campbell.
