Gartner, Inc. is an American research and advisory firm providing information technology related insight. Its headquarters are in Stamford, Connecticut, United States. It was known as Gartner Group, Inc until 2001, when it was then changed to Gartner. 
Research provided by Gartner is targeted at CIOs and senior IT leaders, marketing leaders and supply chain leaders. Gartner clients include large corporations, government agencies, technology companies and the investment community. The company consists of Research, Executive Programs, Consulting and Events. Founded in 1979, Gartner has over 7,800 employees, including 1,280 in research, located in 85 countries.
The company was founded in 1979 by Gideon Gartner. Originally a private company, the Gartner Group was launched publicly in the 1980s, then acquired by Saatchi & Saatchi, a London-based advertising agency, and then acquired in 1990 by some of its executives, with funding from Bain Capital and Dun & Bradstreet. In 2001 the name was simplified to Gartner.
In the course of its growth, Gartner has acquired numerous companies providing related services, including Real Decisions—which became Gartner Measurement, now part of Gartner's consulting division—and Gartner Dataquest, a market research firm. It has also acquired a number of direct competitors, including NewScience in the late 1990s, Meta Group in 2005 and AMR Research and Burton Group in early 2010.
Gene Hall has been the CEO since August 2004.
Gartner has had major controversy in forecasts. In 2009, Gartner predicted the PC market would experience the "sharpest unit decline in history", and a few quarters later it reported "strongest growth rate in seven years".
