From Pandora Internet Radio, a Trenton-based trash-to-cash juggernaut, to a New Orleans reconstruction stalwart, America’s urban cores are home to a host of rising stars. The Inner City 100, a project of the Initiative for a Competitive Inner City, highlights the fastest growing inner city businesses in America. For the 2011 list, ICIC received more than 2,000 nominations. Companies were then ranked by compound annual growth rate (CAGR) based on their revenue over the five-year period between 2005 and 2009 (the last year for which complete data was available). One Stop Environmental made the list again this year coming in at #29.
