When Bryan Sivak joined then D.C. mayor Adrian Fenty’s administration as chief technology officer, he was fresh from building his own business. Five years later, Sivak has become something of a government-embedded entrepreneur. He left the District to become Maryland’s first chief innovation officer in 2011. He is now chief technology officer at the Department of Health and Human Services. There, he manages the IDEA Lab, a series of programs that reward innovation, bring private sector leaders into the agency, and provide employees with time and money to pursue ideas. The effort aims to infuse a sense of entrepreneurship in the risk-adverse temperament of government.
