More than one-tenth of the fastest growing tech companies in Canada are based in the greater Kitchener-Waterloo region, according to the 2015 Deloitte Fast 50 announced Thursday.

The Kitchener-Waterloo region placed six companies on the closely watched list, which assesses revenue growth over a four-year period. Deloitte Canada announced its 2015 version of the program on Thursday.

Heading the list this year is first-time entrant, Montreal-based men’s online clothing retailer Frank & Oak, whose sales soared 18,480 percent in the four-year period.

The top KW company was Waterloo-based Magnet Forensics, which makes software that helps recover data from hard-drives that people have tried to erase or destroy. It placed eighth on the list with a four-year revenue growth of 1154 percent.
