The American Underground was launched in 2010 in the basement of the Strickland Building on the American Tobacco Campus (ATC). The American Tobacco Campus is North Carolina’s largest historic renovation project totaling over one million square feet of space. It transformed what was once an eyesore of abandoned tobacco warehouses into a bustling hub for innovation, catalyzing future business leaders and job creators for Durham and the Triangle. With the addition of the American Underground, it has become the perfect mixing place for entrepreneurs with big ideas and the support to make them happen. After outgrowing the AU @ATC location, the American Underground expanded to two additional locations—one in downtown Raleigh on Fayetteville St. and another in downtown Durham on Main St. With just three companies in 2010 to now over 200 companies, the American Underground has become known as the Startup Capitol of the Southeast.
