The company was founded in 1993 by Janet Lustgarten and Arthur Whitney. Whitney is the developer of the k language. In 2014, First Derivatives increased their ownership interest to a 65 percent share of the privately held company as it began expanding its databases to retail, pharmaceuticals, and utilities. In 2018, First Derivatives announced plans to buy out the remaining shares of Kx Systems. Kx Systems is headquartered in Palo Alto, California, and has further offices in New York City, England, Ireland, Germany, Australia, Singapore, Tokyo, and Hong Kong.
In 1993, Whitney and Lustgarten joined together to commercialize the k programming platform Whitney had created after building the A+ language and other trading systems at Morgan Stanley. The purpose of the software was to access and explore large data volumes in financial services computer systems. Initially, Kx Systems had an exclusive contract with Swiss global financial services firm UBS to provide them with the K language. In 1998, the contract with UBS expired and the firm launched the kdb+ database. As part of kdb+, Whitney developed a new language named q that operates with k and uses English keywords.
In 1999, the firm reached a marketing agreement with Northern Ireland based firm, First Derivatives. Kx Systems opened an office in Manhattan in 2002, offices in Germany and Japan in 2003, and an office in Hong Kong in 2009. In 2014, First Derivatives purchased a 65 percent share of Kx Systems, which began a trend in offering Kdb+ to other data-driven industries. Kx Systems has also partnered with the equity trading platform, IEX Group Inc., to conduct real-time market surveillance, which can be used to monitor actions such as insider trading.
To demonstrate this expansion of Kdb+ into verticals outside of finance, Kx has entered into a partnership with Aston Martin Red Bull Racing and has become a technology supplier to NASA's Frontier Development Lab. As of 2019 Kdb+ is available as an on-demand solution via the Amazon Web Services (AWS) Marketplace. 
As of mid 2018, Kx released a ‘Fusion’ initiative to increase the interface options for kdb+. These include:
