StatSoft. StatSoft is the original developer of Statistica. Dell acquired it in March 2014. Statistica is an analytics software portfolio that provides enterprise and desktop software for statistics, data analysis, data management, data visualization, data mining, which is also called predictive analytics and quality control.

History
StatSoft was established in 1984 as a partnership of a group of university professors and scientists. Its first products had menu-driven libraries of flexible statistical procedures and ran on microcomputer platforms such as Apple II, CP/M, Commodore and MS-DOS.

With the release of Statistica 9 in May 2009, both 32-bit and 64-bit native versions became available. Its current product suite, Statistica 12, was released in May 2013. Statistica is used worldwide at major corporations, government agencies and universities.

On March 24, 2014, StatSoft was acquired by Dell in an effort to bolster Dell's ‘big data’ offering. StatSoft's CEO at the time of the Dell acquisition was Paul Lewicki.

On June 20, 2016, Dell sold Dell Software Group (which included StatSoft) to private equity firm Francisco Partners and Elliott Management.

On May 15, 2017, Quest Software sold Statistica to TIBCO Software.
