Every year, consulting firm Deloitte releases its list of the top 500 fastest-growing North American tech companies. The list ranks the companies that have experienced the most revenue growth over a three-year period, with this year’s ranking taking into account revenue growth from 2017 to 2020.

The 2021 Technology Fast 500 list features tech companies across various industries ranging from media to life sciences, fintech, energy, software development and more. It also features companies from all over the U.S. and Canada.

Washington, D.C. was well-represented on the list this year with 26 companies making the cut, five of which were ranked in the top 50. In fact, one local company ranked second with an impressive 60,259 percent growth in revenue. 

“The greater Washington area continues to be a premier hub for technology and innovation. The region’s tech sector benefits from access to a well-qualified workforce, the ability to attract talent and [its] proximity to the federal government,” Amy Holcomb, Deloitte’s technology, media and telecommunications industry leader for D.C., said in a statement.
