gazelle
n.— «An important measure, especially if you’re interested in job creation and economic impact, is the measure of high-growth start-ups, popularly called “gazelles.” What the creators of this measure understood is that it is not just the size that counts, but how fast a company is growing. The current preferred definition of a “gazelle” company is 20% year-over-year revenue growth, for a minimum of four years.» —“The real face of entrepreneurship” by Richard Stump Business Lexington (Lexington, Kentucky) Jan. 8, 2009.
