Fastest-Growing Tech Companies, Ranked By Fortune

Fortune has published its list of the fastest-growing companies of 2011. This group of innovators also includes several tech companies from around the world that are growing like weeds.

Before qualifying for this list, a company must meet several of Fortune's critera. Principal among those requirements are the following:

[The company] must be trading on a major U.S. stock exchange; report data in U.S. dollars; file quarterly reports with the SEC; have a minimum market capitalization of $250 million and stock price of at least $5 on June 30, 2010; and have been trading continuously since June 30, 2007. Companies must have revenue and net income of at least $50 million and $10 million, respectively, for the four quarters ended on or before April 30, 2010, and have posted annualized growth in revenue and earnings per share of at least 15% annually over the three years ended on or before April 30, 2010.

Among the top 30 of the year's fastest-growing companies, eight are in the tech sector. Take a look at the slideshow (below) to see the top four tech companies. If you're surprised that Apple's not listed, visit Fortune to view the complete list of top 8 tech companies, which includes Apple.
