Deloitte named the next batch of Fast 500 companies.

etrials is 363rd on the list. Since 2001, etrials says, it has grown its revenues by 345 percent; this is the company’s second consecutive appearance on the list.

“Sophisticated technology is becoming the norm and is in almost everything in the 21st century,” said Tony Kern, deputy managing principal of Deloitte’s Technology, Media & Telecommunications industry practice. “etrials has developed technology solutions that deliver in today’s highly competitive world, and we applaud their efforts, ingenuity and teamwork in becoming one of the fastest growing technology companies in North America.”

In addition, entrants must own proprietary intellectual property or proprietary technology that contributes to a significant proportion of the company’s operating revenues.
