Rachel Haot

As the country's first chief digital officer in government, Haot was Mayor Michael Bloomberg's pick, tasked in 2011 with making New York City a tech-friendlier hub. Her team launched the WeAreMadeinNY.com campaign, which maps some 3,000 job openings at more than 1,000 Silicon Alley companies. The NYC.gov site is getting a face-lift thanks to a city-sponsored hackathon, and the city government's social media traffic has nearly tripled.
