Founded in 1993 and listed on the Swiss stock exchange (SIX: TEMN), Temenos AG is a provider of banking software systems to retail, corporate, universal, private, treasury, fund administration, Islamic, microfinance and community banks. Headquartered in Geneva, Switzerland, and with 67 offices in 40 countries, Temenos serves over 3,000 financial institutions in 145 countries across the world.^[3][2] It claims to be used by 41 of the top 50 banks worldwide.^[2][3]

The company was started in November 1993, by George Koukis and Kim Goodall, having acquired the rights to GLOBUS, the successful banking software platform developed by a team of technical and banking experts in 1988. The company was renamed to Temenos, in reference to a lecture on money given by Hans-Wolfgang Frick at the Temenos Academy^[4] (1992), and continued to develop and market GLOBUS.

In 2001, Temenos went public,^[5] and is listed on the main segment of the SWX Swiss Exchange (TEMN). Also in 2001, Temenos acquired a mainframe core banking application aimed at high-end retail banks, originally developed by IBM, and now marketed as Temenos Corebanking.^{[citation needed]}

On 30 September 2003, Temenos launched its T24 banking package. T24 was based on GLOBUS,^[6] but with a state-of-the-art banking technology platform. This was the result of 3 years of development effort and an investment of more than US$24 million.^{[citation needed]}

In 2011, George Koukis stepped down as chairman and became a non-executive director,^[7] and Andreas Andreades became chairman.

In 2021, Temenos has launched a new collaborative fintech marketplace, Temenos Exchange.^[8]

In February 2024, American short-selling firm Hindenburg Research released a report alleging "major accounting irregularities" at Temenos.^[9] Temenos denied the allegations, and announced an independent review.^[10][11]
