Gregory Richard Gianforte (born April 17, 1961) is an American businessman, engineer, author, and politician serving as the Representative for Montana's at-large congressional district since 2017. Gianforte and his wife founded RightNow Technologies, a customer relationship management software company which went public in 2004, before being acquired by Oracle in 2011. Gianforte is one of the few tech executives to be elected to political office in the United States. Since Representative Darrell Issa left office in 2019, Gianforte is currently the second wealthiest member of Congress. He is not running for re-election to the House of Representatives in 2020 and is instead a candidate in the 2020 Montana gubernatorial election.
In 2016, Gianforte ran for Governor of Montana as the Republican candidate, losing to incumbent Democratic Governor Steve Bullock. In May 2017, Gianforte defeated his Democratic opponent Rob Quist in a special election for Montana's at-large congressional seat to fill a vacancy created by the presidential cabinet secretary appointment of Ryan Zinke. Gianforte prevailed in his 2018 bid for re-election after fending off a challenge from Democratic nominee Kathleen Williams.
