Value proposition

Valarian's ACRA platform provides workload-level governance for high-consequence AI systems, enabling sovereign nations and enterprises to deploy AI while keeping data, keys, and control within their own jurisdiction — independent of US cloud providers and model vendors.

Products and solutions

ACRA (control architecture — hardened Kubernetes governance layer with workload-level isolation, policy enforcement, identity, secrets, messaging, audit), Valarian Enterprise (for regulated commercial deployments), Valarian Defence (for air-gapped, sovereign military/national security deployments), Privileged Communication, External Comms Capture

Unique value

The only sovereign infrastructure layer that enforces control at the workload level rather than the cloud level — cloud-agnostic (AWS, Azure, on-prem, air-gapped), customer-held keys (even Valarian cannot access), default-deny architecture, with a non-destructive kill switch for AI workloads. Built by operators from US Special Forces, Palantir, and Darktrace.

Target customer

Governments, defense organizations (NATO member states), regulated enterprises (banks, pharma, airlines), and national security programs

Industries served

Defense & National Security, Government / Public Sector, Regulated Enterprise (Financial Services, Pharmaceuticals, Airlines)

Technology advantage

ACRA extends Kubernetes with a 7-layer control stack (SPIFFE/SPIRE workload identity, internal IdP, Cilium+Istio network isolation, Kyverno policy enforcement, Vault secrets, NATS messaging, full audit). Cloud-agnostic — identical posture across AWS, Azure, on-prem, or air-gapped. Customer holds all cryptographic keys. Deployable in minutes, including in rugged Pelican cases with Starlink at the tactical edge. Supports open-weight and frontier models interchangeably.

How they differentiate

Unlike Palantir — which is a US company subject to the CLOUD Act and increasingly politically contested in Europe — Valarian is a British company built specifically for sovereignty. ACRA is a workload-level governance layer (not a SaaS platform), runs on any substrate, and guarantees customer-held keys so even Valarian cannot access data. Palantir has struggled to win EU contracts due to sovereignty concerns; Valarian positions itself as the European sovereign alternative.

Main competitors

Palantir Technologies (dominant incumbent, $300B+ market cap), Varonis Systems, Veriti

Key partnerships

Cloud-agnostic deployment on AWS, Azure, GCP, and on-premise, works with Kubernetes ecosystem (Cilium, Istio, Kyverno, SPIRE, Vault, NATS, OpenTelemetry), Strategic partnership with Second Front Systems (Feb 2026) to accelerate sovereign defence software deployment across UK and Europe

Notable customers

NATO member states (via Valarian Defence), US government (early contract), regulated enterprises in banking, pharma, and airlines (via Valarian Enterprise)

Major milestones

2020: Founded as Worldr by Max Buchan, 2023-2024: Built and hardened ACRA platform, 2025-05: Emerged from stealth with $20M seed funding, launched Valarian Defence, 2025: Landed US government contract, 2026-07: Raised $50M Series A led by NEA (total $70M), marking NEA's first defense/dual-use investment in Europe

Growth metrics

Hundreds of enclaves deployed across 4 continents; 32-50 employees

Market positioning

Positioned as the sovereign infrastructure layer for the free world — the European alternative to Palantir for governments and defense organizations that need AI capabilities without ceding data control to US tech giants. Addresses the $447B+ European defense spending market and the growing sovereign AI infrastructure gap.

Geographic focus

UK, EU, and Middle East; NATO member states; governments seeking sovereign digital infrastructure outside US control

Patents and IP

Co-author of six cybersecurity patents (Head of Engineering Ciaran McKey from Darktrace)
