About the business:
Ten years ago, Centro founder and CEO Shawn Riegsecker saw an emerging opportunity: new technologies were going to create complexity for ad agencies and force them to place ads across more devices. Riegsecker built Centro to help ease the transition for media companies by doing the heavy tech lifting so that ad agencies could focus on the creative aspects of their work. Internally, Centro takes care of its employees with a handful of perks, including free yoga and a paid three-week-long sabbatical for anyone who has worked at the company for four years.

The Initiative for a Competitive Inner City (ICIC) defines inner cities as core urban areas with higher unemployment and poverty rates and lower median incomes than their surrounding metropolitan statistical areas. For the 2012 list, ICIC received more than 2,000 solicited nominations using its database of small businesses and through the support of its nominating partners, including the U.S. Hispanic Chamber of Commerce, Staples, New York City Department of Small Business Services, and the U.S. Conference of Mayors. Companies were ranked by compound annual growth rate (CAGR) based on their revenue over the five-year period between 2006 and 2010, the last year for which complete data was available. This list was audited by the independent accounting firm of Rucci Bardaro and Barrett, PC.
