Ms. Wojcicki was functioning for Intel at the time, and a single day, she wasn’t capable to obtain an essential piece of data due to the fact Google was down. She realized that she had grow to be dependent on “the internet site created by these two dudes in my garage.” Ms. Wojcicki joined Google as its 16th employee and its initially promoting manager.

With a child on the way, she was going to perform for a enterprise with no income. She helped turn Google into a juggernaut, building its signature marketing item, AdWords, and overseeing its initially foray into content material sharing, named Google Video. In 2006, swallowing her pride, she encouraged Google to obtain a rival service named YouTube for $1.65 billion. (Morgan Stanley lately estimated that the division is now worth $160 billion.)

More than the years, Ms. Wojcicki constructed a private fortune estimated in the hundreds of millions, and she remains a close confidant of Mr. Web page, who is now the chief executive of Google’s parent, Alphabet. 1 former executive told me, “Susan is the initially cousin of the Google royal household.”

Ms. Wojcicki’s biological household is remarkably achieved. She is the oldest of 3 sisters the middle a single, Janet, is an anthropologist, epidemiologist and former Fulbright scholar and the youngest, Anne, co-founded 23andMe, the DNA testing enterprise. (Anne was also married to Mr. Brin till 2015.)

Becoming portion of a higher-profile clan can bring about confusion. Chris Dale, a YouTube spokesman, as soon as discovered that Persons magazine planned to run a story that Susan Wojcicki was dating Alex Rodriguez, the former New York Yankees slugger. Mr. Dale recalls sheepishly calling his boss — who had been married for extra than 20 years — in the middle of a parent-teacher meeting to ask if she was obtaining an affair. She was not. Anne, not Susan, had been seeing Mr. Rodriguez.

Considering that taking more than YouTube, fame has been anything Ms. Wojcicki has attempted to stay away from. But she is warm and approachable in particular person, and for a single current interview, she arrived at the workplace dressed like any other Google employee, with black cowboy boots and a backpack slung more than a single shoulder, prepared to go over her track record. “One way I feel about some of the choices is placing myself in the future and considering: in 5 or 10 years, what will they say?” Ms. Wojcicki stated. “If a person had been to appear back on the choices that we’re producing, would they really feel we had been on the suitable side of history? Would I really feel proud? Will my youngsters really feel like I produced fantastic choices?”

No matter whether vacuous or violent, YouTube troubles arise at a dumbfounding pace. Final year, YouTube banned each the “Tide Pod” challenge, which involved biting into laundry detergent pods, and “No lackin” videos, in which participants aim guns at every other. Confronted by a single crisis just after yet another, Ms. Wojcicki has introduced policies to curb the spread of problematic videos and raised the bar on which videos can carry marketing. The challenge is cleaning up the mess although maintaining her a variety of constituencies — customers, creators, advertisers, parents, lawmakers — pleased, or at least not irate.
