Technology Fast 500 provides a ranking of the fastest growing technology, media, telecommunications, life sciences and clean technology companies in North America. This ranking is compiled from nominations submitted directly to the Technology Fast 500 Web site and public company database research conducted by Deloitte. Technology Fast 500 award winners for 2009 are selected based on percentage fiscal year revenue growth during the five-year period from 2004 to 2008.

In order to be eligible for Technology Fast 500 recognition, companies must own proprietary intellectual property or proprietary technology that contributes to a significant portion of the company's operating revenues. Using other companies' technology or intellectual property in a unique way does not satisfy this requirement. Consulting companies, professional service firms, etc. are not eligible unless they have proprietary technology that contributes to a significant portion of their operating revenues.

Technology Fast 500 award eligibility requirements also include base-year operating revenues of at least $50,000 USD or CD and current-year operating revenues of at least $5 million USD or CD. These revenues must have more than doubled between 2004 and 2008. Additionally, companies must be in business for a minimum of five years, and be headquartered within North America.
