At $16.4 million, the 2010 revenue of St. Petersburg's Crystal Clear Technologies is up 16,048 percent from the $101,455 it made in 2007. That enormous gain placed the 12-employee company at No. 5 on Inc. magazine's annual Inc. 500 list of the country's fastest-growing companies. Crystal Clear Technologies says it provides information technology services to the military and government and advises companies, mostly military suppliers, seeking help through federal procurement policies. Last year, the company ranked 549th on the larger Inc. 5,000 list of fast-growing companies. The firm is the highest-ranking Florida company on this year's Inc. lists, which rank firms by revenue growth.
