AI that runs on your hardware. Not theirs.

Cloud AI is metered, foreign-hosted, and rented by the token. Arsenale runs frontier-class models on hardware you already own. Sovereign by construction, under £0.01 per agent decision, zero data egress.

Designed for the sectors where the cloud is the wrong answer

Six markets where on-premise, air-gap-capable, customer-owned hardware isn't a compromise. It's the requirement in the RFP.

Defence

Sovereign compute for command, control, ISR, and tactical decision support. Air-gap-capable. No cloud dependency in theatre. The agent runtime that runs business operations runs operational decision loops too.

Government

AI on every knowledge-worker desk, off the foreign cloud, off the recurring-opex line. Per-desk economics that compare to a standard workstation refresh, not a SaaS contract.

Healthcare

Patient-record-grade data sovereignty by construction. The appliance lives on the trust's network, on the trust's hardware, with no foreign cloud in the loop and no patient data leaving the building.

How it deploys on the desk →

Critical Infrastructure

Energy, water, transport, telecoms: operators where outbound connectivity is a risk surface, not an assumption. Air-gap deployment as the default, not the exception.

How it deploys on the desk →

Public Safety

Police, justice, border, emergency services: environments where evidence integrity, audit trails, and chain of custody are operational requirements, not nice-to-haves. Tamper-evident logs that live with you.

How it deploys on the desk →

Financial Services

Regulated workloads where data residency, third-country transfer rules, and operator-continuity expectations (DORA, FCA SYSC) make foreign cloud genuinely inappropriate. UK-domiciled compute on hardware you own.

Local AI, on your own hardware

Cloud AI charges you per token, ships your data through someone else's infrastructure, and locks you into pricing you don't control. Every prompt is a meter spinning. Every document a sovereignty risk. Every API outage a single point of failure for your entire operation.

Arsenale inverts the model. We deploy teams of specialised agents that monitor, analyse, and act across your operation (finance, compliance, risk, legal, infrastructure) around the clock, on your hardware. Your data never leaves your building. Inference is unmetered. The system thinks locally, acts locally, and learns from your business, not anyone else's.

Capabilities

Each agent is a specialist. Together, they form a workforce that covers every department a company needs, without hiring.

Corporate Governance

Deadline tracking, filing compliance, board resolution drafting, statutory register monitoring across multi-entity structures.

Financial Operations

Treasury monitoring, intercompany invoicing, runway analysis, contract management, accounts preparation.

Risk & Compliance

Real-time risk assessment, regulatory scanning, circuit breakers, macro-economic monitoring, drawdown management.

Infrastructure

Server health monitoring, disk/memory/latency tracking, ledger divergence detection, automated alerting.

Legal

Document drafting, IP assignment tracking, licence agreement generation, compliance gap analysis.

Intelligence

Email triage, macro digest processing, market surveillance, cross-agent synthesis, daily executive briefings.

Architecture

The entire stack runs on a single machine: model, runtime, agents, dashboard, all under one roof. No internet required for inference. No tokens metered. No vendor lock-in. No data egress. The cloud's failure modes (outages, rate limits, pricing changes, jurisdictional risk) are not failure modes for Arsenale because the cloud is not in the loop.

Trajectory

The cloud sells AI as a service. We sell it as infrastructure you own outright. Closing that stack (application layer, model weights, silicon) is the work.

Today

Sovereign AI runtime in production. 120B-parameter MoE on consumer hardware at 18 tokens per second, under £0.01 per decision.

Next

Our own model weights. Trained on UK compute. Tuned for the agent workloads our customers actually run.

Long horizon

Silicon design. Closing the sovereign stack from application layer to the metal.

Why "Arsenale"

The Arsenale di Venezia was the first mass-production facility in human history. At its peak, 16,000 workers could build a fully-equipped warship in 24 hours. Assembly-line manufacturing, centuries before Henry Ford. The English word "arsenal" derives from the Venetian Italian "arsenale."

We took the name because we're building the same thing for intelligence. A production facility, not for ships but for autonomous agents that do the work of entire departments. Same city. Same principle. New century.
