Founded2018

OpenGamma was a financial technology company founded in 2009, renowned for pioneering open-source risk management solutions for the financial services industry, particularly in derivatives and fixed income markets. Its core mission was to bring transparency, flexibility, and standardization to complex risk analytics. OpenGamma's platform enabled financial institutions to better manage and understand their risk exposures. In November 2018, OpenGamma was acquired by the London Stock Exchange Group (LSEG). Its technology, expertise, and open-source ethos have since been integrated into LSEG's Data & Analytics division, contributing to their comprehensive suite of risk management, post-trade, and market data services, enhancing LSEG's capabilities in providing sophisticated risk solutions to a global client base.

Therefore, executive movements specifically for 'OpenGamma' as a standalone entity are not applicable in the last 12 months. Any leadership changes related to the former OpenGamma technology or business lines would occur within the LSEG management structure, particularly within its Data & Analytics or Post Trade divisions. Public announcements of such changes would be made by LSEG.
