ComputeVault is a prefabricated, waterproof, underground AI compute vault — delivered as one sealed unit, lowered by crane, and built to disappear into the property it powers. Sovereign compute, hidden in plain sight.
Above grade, nothing but a flush landscape cap, a boulder feature, or a discreet utility cover. Below grade, a sealed concrete vault running a private GPU cluster — your own data, your own models, on your own land. No public cloud, no shared tenancy, no one else's terms of service.
Fabricated, tested, and sealed in the factory. Trucked in one piece, lowered by crane, connected, and live.
Flush cap, boulder, or utility cover — the vault reads as landscaping. Only the lid is ever visible.
Watertight, flood-proof, seismic-resilient, thermally stable. Designed to run through storms, drought, and grid outages.
From an estate-class unit hidden under the lawn to a half-megawatt institutional control center — every ComputeVault shares the same sealed-shell, liquid-cooled, lift-serviced architecture. Choose by power, not by compromise.
The flagship residential unit. A complete, watertight underground compute system for luxury residences and high-performance home labs — closed-loop liquid cooling, electric/hydraulic service lift, and optional integration with geothermal, pool, rainwater, and graywater loops for thermal optimization.
The estate-to-enterprise bridge: a 26-foot poured-in-place reinforced shell with a 1.2M BTU/hr cooling capacity, hydraulic lift rack assembly, MERV-13 ventilation, battery energy storage (BESS), and full utility connection set. A 100-year structural design life with a service-lift system that raises the entire rack assembly above grade for clean maintenance.
The institutional control center. NVIDIA HGX / DGX-ready, direct-to-chip liquid cooled, N+1 / N+2 redundant, and fully off-grid capable. Cross-section and isometric X-ray views expose every subsystem — CDU, switchgear, LFP battery backup, VESDA-monitored clean-agent suppression, and a six-option cooling-integration manifold.
The defining engineering move: a sealed below-grade compute envelope, with heat rejection and service access brought to the surface. The compute stays dark, dry, and secure; the heat and the hands reach it from above.
Heat, power, and compute density are the three constraints that define this product. Here is how each is handled — drawn straight, not glossed.
A vault that hides the physics is a liability, not a product. These four constraints are designed for explicitly — and every deployment is confirmed by licensed PE stamps per jurisdiction.
A loaded AI rack rejects 40–130 kW; you cannot dump that into sealed soil. Every unit uses direct-to-chip liquid cooling that rejects to an above-grade dry cooler or ground loop. The "garden feature" on the surface is functional, not decorative.
A single high-density node draws 10–15 kW; estate tiers routinely exceed a home's spare electrical service and need a service upgrade or dedicated three-phase feed. Every install begins with a utility-approved load study — not an assumption.
Powered, data-bearing, below-grade structures touch building, electrical, fire, stormwater, and confined-space codes at once. Clean-agent suppression includes pre-discharge alarm and abort; a fire-protection PE is on record for every build.
ComputeVault integrates NVIDIA-class GPUs and pursues NVIDIA-Certified / DGX-Ready validation. NVIDIA does not fund, endorse, or sponsor ComputeVault; all marks shown are for hardware identification only.

Run and fine-tune private models on-prem — no per-token billing, no data leaving the property.
Throughput-heavy pipelines for research, simulation, and digital-asset workloads.
A household or firm-wide assistant whose memory and data are physically yours.
A self-contained compute lab for teams that need control, air-gapping, and uptime.
Law firms, clinics, and family offices needing on-prem custody for privileged data.
Battery + genset + off-grid capability for continuity through outages and disasters.
The cloud is someone else's computer, on someone else's terms. ComputeVault is the opposite stance: infrastructure that belongs to you, buried on your land, answering only to you. Quiet on the surface. Relentless underneath.
