Quantexa has been awarded a £175 million, 10-year partnership by HM Revenue and Customs (HMRC) to modernise its data foundation and enable sovereign, governed AI at national scale in one of the public sector’s largest Decision Intelligence deployments.

The initiative will seek to drive efficiency across key workflows, protect public funds, and enhance the customer experience for the UK taxpayer. HMRC has also seen an uptick in dissatisfaction from the public; 2024-2025 saw the tax collector gain 93,000 complaints according to a Freedom of Information request.

This programme will support the modernisation of HMRC’s core data infrastructure, giving the UK’s tax authority a clearer, connected view of its data to improve performance, help identify tax at risk, and strengthen control.

It also lays the groundwork for advanced AI capabilities and supports wider transformation efforts; from closing the tax gap to delivering faster, more seamless customer service.

Public sector organisations are accelerating digital transformation while needing to maintain sovereignty, auditability and control.

Vishal Marria, Founder & CEO, Quantexa: “Governments around the world are facing a common challenge: how to turn complex, fragmented data into confident, timely decisions. By creating context from data and embedding trusted, governed AI, we are helping HMRC improve how public sector organizations make confident, informed decisions. This is a blueprint for how the UK government deploys AI at scale.”

The appointment of a UK-based company is more in line with government initiatives to put British companies first after MPs raised their concerns over government contracts continually going to foreign-based tech companies.

Quantexa secured a $2.6 billion valuation just last year following a $175 million series F; the firm achieved unicorn status in 2023.

AI Minister Kanishka Narayan said: “Quantexa is at the forefront of British innovation, developing the technologies we need to power next generation digital public services that are smarter and more secure. This partnership will help HMRC to deploy AI safely at scale, bringing its data together to support better decisions, improve efficiency and deliver a stronger service for taxpayers.

“By using advanced data tools to identify risks and automate routine tasks, HMRC can focus its efforts where they matter most. This is a practical step that paves the way for a better service for taxpayers.”

Ceri Morgan, HM Trade Commissioner for Europe, said: “This announcement underscores the strength of the UK’s advanced data and AI ecosystem, and its relevance to governments around the world. Quantexa’s work with HMRC shows how UK-developed technology can deliver impact at national scale—supporting more efficient public services, safeguarding revenues, and enhancing the taxpayer experience. It’s exactly the kind of innovation we are keen to share with international partners.”
