Former leaders at GCHQ & Darktrace have raised £16 million to expand Prevalent AI in the United States.
The bootstrapped cybersecurity company has built a data fabric and knowledge graph over the last nine years which is used by several leading global enterprises.
The funding comes from Los Angeles-based Integrity Growth Partners and marks Prevalent AI’s first primary capital raise.
Gartner predicts that more than 40% of agentic AI projects will be cancelled by the end of 2027, citing escalating costs, unclear business value, and inadequate risk controls. Underneath all three is the same problem: context.
AI systems can only make reliable decisions when they operate on data that is clean, connected, and continuously current. For almost a decade, Prevalent AI says it has been solving that challenge for some of the world’s largest banks, telecommunications providers and insurers, among others.
Its data fabric combines hundreds of fragmented enterprise data sources into a continuously updated sovereign knowledge graph. Proven first in cybersecurity, where fragmented data creates immediate operational risk, the platform provides organisations with a trusted source of context that allows both people and AI systems to understand what exists across the enterprise, how it relates, and where operational gaps remain.
Prevalent AI was founded in 2017 by Paul Stokes (CEO) and Arun Raj (COO) alongside a team with intelligence-community heritage, including former director of GCHQ, Sir Iain Lobban, and Andrew France, deputy director for cyber defence operations at GCHQ and co-founder & CEO of DarkTrace.
The Prevalent AI team has spent nearly a decade building its business without external growth capital, expanding through founder-led customer demand while remaining profitable since its first customer. In 2021, Istari (part of Temasek, Singapore’s sovereign wealth fund) became a minority shareholder through a secondary transaction.

“Large enterprises do not have a shortage of tools or data. They have a shortage of context,” said Stokes.
“Security teams are being asked to make decisions across thousands of systems, controls, identities, and data sources that were never designed to work together. For almost a decade, we have been using AI to continuously clean, connect, and contextualise enterprise data so organisations can see what exists, what is working, where the gaps are, and what needs attention.
“We started with security because that is where fragmented data does the most damage. The investment from Integrity Growth Partners allows us to scale our business beyond cybersecurity into every enterprise function where decisions depend on connected, trusted data.”
The company will strengthen its leadership team following the recent appointment of Stuart Barnard as CFO and Mike East as SVP of global sales.
“Paul, Arun, and the team have built something rare: genuinely differentiated, AI-native technology that the most sophisticated enterprises in the world rely on, all while maintaining remarkable capital discipline,” said Ryan Anderson, managing partner and co-founder at IGP.
“As enterprise security stacks grow more complex and agentic AI raises the stakes on data quality and depth, the need for Prevalent AI’s unified, context-driven foundation will only intensify.
“We have deep respect for what the founding team has built, patiently and with real substance, and we are proud to partner with them as they lead the company into its next stage of growth.”
