Power 50: Megan Smith

For more than a decade, Megan Smith was a top exec at Google, overseeing the tech giant's DotOrg philanthropic efforts and serving as vice president of Google[x] (which developed the ill-fated Google Glass). In September 2014, the former CEO of PlanetOut was named the chief technology officer of the United States (the first woman in that post), a gig that tasks her with managing the government's tech needs, including the Healthcare.gov Web site, and the effort to keep the Internet free and open. She's also an advocate for recruiting more talented women into positions of power, stating, "It's our country, so if we show up or not, that shapes what our government's going to be."
