In the 2010 ranking of the 500 fastest-growing public and private technology companies in North America, eZanga.com made its first ever appearance on Deloitte’s Technology Fast 500 list, coming in at No. 158.

The Fast 500 awards are based on percentage of fiscal year revenue growth from 2005 to 2009 and recognizes all areas of technology including media, telecommunications, life sciences and clean technology. eZanga.com saw a 657% revenue growth in that five-year span between ’05 and ’09.

As a result of its high placement on that list, eZanga.com was also listed in this year’s Greater Philadelphia Fast 50 list at No. 2 for the second consecutive year. The Philly Fast 50 employs the same criteria as the Fast 500 to recognize the companies with the biggest five-year growth in the Greater Philadelphia region.
