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.
Served as the global headquarters, housing core operations, product development, engineering, quantitative research, and corporate leadership for OpenGamma before its acquisition by LSEG.
Located in a central London area known for finance and technology, providing a modern and collaborative workspace. Specific architectural details are not widely publicized.
OpenGamma fostered an innovative, agile, and technically-driven work culture, heavily influenced by its open-source philosophy. This encouraged collaboration, transparency, and a focus on solving complex financial challenges.
Its London headquarters strategically positioned OpenGamma within one of the world's leading financial hubs, facilitating close proximity to clients, partners, talent, and the broader fintech ecosystem.
Prior to its 2018 acquisition by LSEG, OpenGamma established a global presence primarily through its London headquarters and New York office, serving financial institutions across Europe, North America, and potentially Asia with client support. The open-source nature of its core technology facilitated worldwide adoption and community engagement. Post-acquisition, OpenGamma's technology and expertise have been integrated into LSEG's global Data & Analytics offerings, extending its reach and impact through LSEG's extensive international network and client base.
