Pennsylvania, 187 companies

With the decline of Pennsylvania's once formidable manufacturing sector—particularly the coal and steel industries—has come a complementary increase in the services industry. ModCloth, an online retailer of affordable women's fashion designs, exemplifies Pennsylvania's new economy. The company lands at No. 2 on the 2010 Inc. 5000 list, growing 17,000 percent over the past three years to almost $16 million in revenue.
