About Quantexa
Founded in London in 2016, Quantexa specialises in Decision Intelligence, helping organisations connect siloed data and uncover complex relationships across their operations. Its platform is used by global banks such as HSBC, Standard Chartered and Danske Bank, as well as public-sector bodies including the UK Cabinet Office’s public-sector fraud agency.
In 2025 Quantexa closed a $175m Series F round led by Teachers’ Venture Growth, aimed at expanding into new verticals and accelerating development of its AI and graph-analytics capabilities. Quantexa reached a valuation of roughly $2.6bn following this round.
In May 2026, Quantexa also won a major £175m, 10-year contract with HMRC to modernise the UK tax authority’s data infrastructure and support the use of governed AI across areas such as fraud detection and operational decision-making.
