KX is a privately owned software company that sells a time series database kdb+, used for financial modeling and data analysis, and its associated proprietary programming language q.[6][7]

It was founded in 1993 by Janet Lustgarten and Arthur Whitney,[8] the developer of the K programming language. In 2014, First Derivatives increased their ownership interest to 65 percent; in 2018, the company (now FD Technologies plc) announced plans to buy out the remaining shares of KX.[9] KX has offices in New York City, London, England, Ireland, Germany, Australia, Singapore, Tokyo, and Hong Kong.[1][10]

Overview

In 1993, Whitney and Lustgarten joined to commercialize the k programming platform Whitney had created after building the A+ language and other trading systems at Morgan Stanley.[7][11] The purpose of the software was to access and explore large data volumes in financial services computer systems.[12] 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 operated with k and uses English keywords.[13]

In 1999, the company reached a marketing agreement with a Northern Ireland based firm, First Derivatives.;[14] it opened an office in Manhattan in 2002,[15] Germany and Japan in 2003,[16] and Hong Kong in 2009.[17] In 2014, First Derivatives purchased a 65 percent share of Kx Systems.[18] Kx became a technology supplier to NASA's Frontier Development Lab.[19] In July 2018, FD Technologies bought all remaining shares in KX Systems that it did not already hold;[20] Whitney and Lustgarten then went on to found Shakti.[21][22]

In 2025, FD Technologies sold KX to TA Associates as part of their downsizing of spinning-off divisions such as the company and other subsidiary First Derivative which was sold to EPAM Systems.[23][24]
