London-based sovereign infrastructure startup Valarian has secured $50 million in a Series A funding round led by global venture capital firm New Enterprise Associates (NEA), bringing the company’s total funding to $70 million. The investment will accelerate the development of its sovereign infrastructure platform designed for mission-critical AI systems, enterprise applications, and defence operations.
The funding round marks a significant milestone for both companies, as it represents NEA’s first-ever defence and dual-use investment in Europe. Existing and new investors including Lightbank, XTX Markets, Sequel, LitVC, along with prominent angel investors Gokul Rajaram and Nikesh Arora, also participated in the financing.
Growing Demand for Sovereign AI Infrastructure
As governments and enterprises increasingly rely on artificial intelligence for critical operations, concerns over infrastructure control, data governance, and national security continue to grow.
Valarian is positioning itself to address these challenges by developing a sovereign infrastructure platform that enables organizations to retain complete operational control over AI-driven workloads, critical applications, and sensitive data environments.
The company believes that as AI becomes central to public services, defence systems, and enterprise operations, infrastructure sovereignty will become an essential requirement rather than an optional feature.
Building the Control Layer for Critical AI Systems
Unlike traditional cloud security platforms, Valarian operates at the infrastructure layer, allowing organizations to enforce governance policies automatically across every deployed application and AI workload.
Its platform enables customers to:
- Control how AI systems communicate across environments
- Govern access to sensitive operational data
- Maintain workload-level security and compartmentalization
- Enforce infrastructure policies automatically
- Support mission-critical applications across enterprise and government sectors
By embedding governance directly into infrastructure, organizations can deploy AI while maintaining greater operational independence and regulatory compliance.
Funding to Accelerate Enterprise and Defence Expansion
Valarian plans to use the newly raised capital to scale both of its primary business divisions.
Valarian Enterprise
The enterprise platform is designed for organizations deploying artificial intelligence and other business-critical applications that require enhanced governance, workload isolation, and operational oversight.
Valarian Defence
The defence-focused platform supports sovereign governments and military organizations operating highly sensitive workloads where infrastructure control, security, and resilience are essential.
The company expects growing adoption as governments worldwide continue increasing investments in AI-enabled national security capabilities.
Founder Highlights Importance of AI Sovereignty
Valarian CEO and Co-Founder Max Buchan believes that the future of artificial intelligence depends not only on developing powerful AI models but also on controlling the environments in which those systems operate.
According to Buchan, sovereignty must be designed into infrastructure from the beginning, allowing governments and enterprises to maintain control over their digital operations instead of relying entirely on external providers.
He noted that the new investment will help expand Valarian’s architecture to organizations facing increasing demands for secure and sovereign AI deployments.
NEA Makes First European Defence Technology Investment
For NEA, the investment reflects a growing belief that sovereign infrastructure represents one of the most important technology opportunities emerging during the AI era.
The firm’s leadership views infrastructure control as becoming just as important as advances in AI models themselves.
By backing Valarian, NEA aims to support the development of foundational technology that enables governments and enterprises to operate AI securely while maintaining strategic independence.
UK Government Supports Domestic AI Innovation
The funding announcement also received support from senior officials within the United Kingdom government, highlighting the strategic importance of domestic AI infrastructure.
Government leaders have emphasized that sovereign AI capabilities will play a vital role in strengthening both economic competitiveness and national security.
As countries race to deploy advanced AI technologies, maintaining control over the infrastructure supporting those systems is becoming an increasingly significant policy priority.
The investment aligns with broader UK initiatives focused on expanding sovereign AI capabilities and strengthening the nation’s technology ecosystem.
Rising Defence Spending Creates New Opportunities
Global defence organizations are accelerating investments in artificial intelligence, automation, and digital transformation.
Europe alone recorded defence spending of €392 billion during 2025, reflecting increased focus on modern military capabilities and secure digital infrastructure.
As NATO member nations continue integrating AI into defence operations, demand is rising for platforms that allow governments to maintain ownership, governance, and operational control over critical systems.
Valarian believes this shift creates a significant opportunity for sovereign infrastructure platforms purpose-built for defence and high-consequence operational environments.
Positioning for the Next Phase of AI Infrastructure
Founded by Max Buchan and Josh McLaughlin, Valarian is building technology designed to serve both commercial enterprises and government organizations seeking greater control over AI deployment.
With fresh funding, an expanding customer base, and increasing global attention on sovereign AI, the company plans to accelerate product development while expanding deployments across enterprise, defence, and public-sector environments.
As artificial intelligence becomes increasingly embedded within critical national infrastructure, platforms that prioritize governance, security, and operational sovereignty are expected to play a central role in the next generation of AI adoption.
