==Overview==
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 UBS to provide them with the K programming language. In 1998, the contract with UBS expired and the company launched the kdb database. As part of the database, Whitney developed a new language named Q that operates with K and allows the use of English words as functions.
In 1999, the company reached a marketing agreement with Northern Ireland based, First Derivatives. The agreement would eventually lead to First Derivatives owning a 65 percent share of the company.〔 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 the company and Kx Systems began offering its database to other data driven industries.〔 The company has also partnered with the equity trading platform, IEX Group to carry out real-time market surveillance, which can be used for monitoring actions such as insider trading.
