Our take
Quantexa specialises in data connectivity, offering companies a vital tool to streamline their information. By bringing together diverse data sets and enhancing internal information with external resources, it enables organisations to generate valuable insights, facilitating more informed decision-making processes.
Since its inception in 2016, Quantexa has experienced exponential growth, establishing a global presence with offices spanning various continents. Its clientele includes prestigious names such as HSBC and Shell, underscoring its reputation as a trusted partner in the realm of data analysis and interpretation.
Enterprises today recognise the untapped potential within their data repositories, yet many lack the in-house expertise to effectively leverage this resource. Quantexta fills this gap, as evidenced by its strategic collaboration with the British government's Public Sector Fraud Authority, securing a Lucrative £4M contract in 2023. Through this alliance, Quantexa aims to combat fraud within the public sector by applying its advanced analytical capabilities to identify and address fraudulent activities.
