The problem we solve

Cloud teams provision storage for the worst hour of the year and pay for it 8,760 hours a year. A typical 1 TB pool on Azure Premium SSD runs $135/month, regardless of whether you're using 80 GB or 800 GB of it.

Storagetax watches your VMs in real time, surfaces the savings the moment they exist, and — on your signal — creates a right-sized pool during your maintenance window. After that, it autonomously expands during surges, shrinks during quiet hours, and reclaims orphaned disks. No downtime, ever.

What you get

Live observability

Per-VM, per-mount, per-device metrics streamed over WebSocket. Spot a runaway log file before it pages your on-call.

Right-sizing you control

You schedule the first pool creation when you're ready. After that, storage grows during surges and shrinks during quiet hours — autonomously, with no restart and no downtime.

Bill back what you actually use

Per-team, per-tag dashboards showing capacity vs. used vs. paid. Drives the conversation that ends "we'll right-size next quarter".

How it works

1.  We watch your storage 24/7

Your VMs send health metrics every few seconds. We analyze trends to spot over-provisioned disks costing you money.

2.  You choose when to optimize

When we find savings, you click Schedule pool optimization. We create the new storage during your off-hours so your live workload isn't disrupted.

3.  We manage it forever

After the pool is created, we autonomously expand it when load spikes, shrink it when usage drops, and run safe maintenance (scrub, defrag, rebalance) on a quiet schedule. Everything's auditable in your dashboard.

Five focused services, one job each. None run in your environment except the agent.

Trust by design

  • Agents dial out only. Zero inbound ports. Zero SSH keys held by us.
  • Tenant isolation. Every row is keyed by client_id; cross-tenant queries are impossible by construction.
  • Bring your own secrets. Cloud credentials are stored encrypted, never logged, and used only to enumerate disks we're allowed to touch.
  • All operations are auditable. Every expand, shrink, and reclaim is logged with the trigger reason and the agent that signed it.
