Substrate
noun
An underlying layer that supports complex systems.
Composable GPU infrastructure — configure compute by cores, VRAM, memory, and storage.

How it works
Compute, assembled to your needs
Instead of renting fixed machines, configure exactly the resources your workload requires.
Choose cores
Select the number of GPU cores for your training or inference workload. Substrate allocates dedicated cores, never shared.
Add VRAM
Allocate video memory precisely for model weights, KV caches, and activation tensors. No memory tax from co-tenancy.
Add RAM
Set system memory for data loading, preprocessing, and host-side buffers. Scale independently from GPU resources.
Add storage
Attach NVMe SSD storage for datasets, checkpoints, and artifacts. Provisioned in seconds, billed per GB used.
Why it matters
Infrastructure without fixed shapes
No oversized instances
Only allocate the resources you need. No paying for idle cores or unused memory sitting in a fixed SKU.
Predictable performance
Dedicated cores and memory, not shared bursts. Consistent throughput for every job, every time.
Built for AI workloads
Training, inference, rendering, simulation. Infrastructure shaped for the demands of modern compute.
Per-second billing
Pay for exactly what you run. Billing stops the moment your job ends — no rounding to the nearest hour.
Instant teardown
Instances are fully cleaned and returned to the pool in seconds. No lingering costs, no stale state.
API + Terraform native
First-class Terraform provider and REST API. Integrate into any existing IaC pipeline in minutes.

Trust & compliance
Enterprise-grade security, built in
SOC 2 Type II
Audited annually. Full audit report available under NDA.
HIPAA Compliant
BAA available. PHI-safe infrastructure for healthcare AI.
Zero Data Logging
We never inspect, log, or retain your workload data. Your models stay yours.
100% Renewable
Hosted in Lefdal Mine — powered entirely by Norwegian hydropower.
“Your infrastructure should never be the weakest link in your security posture.”
Infrastructure
Built inside a mountain
Substrate runs on infrastructure housed in Lefdal Mine Datacenter — a former NATO mining facility carved into the mountains of western Norway. The facility provides Tier III equivalent reliability with natural physical security that no above-ground data center can match.
Cooled by fjord water from the Norwegian Sea and powered entirely by renewable hydroelectric energy, Lefdal delivers exceptional power efficiency with a PUE below 1.15 — making it one of the greenest data centers in the world.
