The cloud coexistence ledger

Make the
old bill stop.

StackVolt tells enterprises what is safe to shut down after a cloud migration, proves it, and prices every day they don't.

The unfinished half of migration

Cutover changed the traffic. It didn't stop the spend.

Modernization runs old and new estates side by side for one to three years. The evidence of what replaced what is scattered across migration tools, flow logs, CMDBs, tickets, and people's memory—so no one wants to own a shutdown, and yesterday's infrastructure becomes a permanent line item.

Hyperscalers won't close it

They monetize consumption. Every month the old estate stays on is revenue—and the tool that ends the tail works against the seller's incentive.

FinOps can't close it

Cost tools see idle resources, not migrated ones. Idle because migrated looks exactly like idle waste—so nothing ever gets certified.

Migration tools go silent

Wave planners own the journey to cutover. Their record stops precisely when the shutdown question begins.

From inventory to verdict

Evidence in. Old estate out.

One read-only connection builds the fleet inventory; the ledger turns that inventory into verdicts. Every asset carries its migration state—and every report states what it could not see.

01

Connect read-only

Federated access only—no agents, no stored cloud credentials, no change permissions. Every estate you connect joins one cross-cloud fleet inventory.

02

Rebuild the lineage

Map every source asset to its modern replacement while migration evidence still exists—it decays in weeks, not years.

03

Certify the shutdown

Verify replacement, traffic, dependencies, and human approval in one durable, append-only record.

The StackVolt platform

Every asset gets a verdict. Every verdict keeps its proof.

Inventory tools tell you what exists. StackVolt starts there—one fleet across both estates—then adds the state that matters after cutover: what replaced each asset, whether it is safe to retire, who approved it, what waiting costs, and whether the landing zone stays clean.

  • One fleet inventory across source and target estates
  • Source-to-target lineage with evidence tiers
  • Traffic, dependency, and replacement verification
  • Append-only decisions with segregated approval
  • Daily burn on every unresolved asset
  • Migration velocity and landing-zone drift guardrails

The deeper why

Dashboards show. Ledgers settle.

Why a ledger, and not another dashboard? Because the durable artifact of a migration is not a picture of your estate. It is the proof of what you were allowed to turn off.

Detection

A feature anyone can ship

Flagging an idle resource is cheap and copyable. Every inventory, FinOps, and security tool already does it.

Attestation

A record no one can rebuild

Who certified the shutdown, on which evidence, with whose approval—written once, kept permanently. Once the migration team disperses, it can never be reconstructed.

Compounding

An asset that appreciates

Every certification makes the next one faster and safer. The ledger becomes the program's institutional memory—and the reason to stay.

One operating truth

Built for the people who have to finish the migration.

For cloud leaders

A migration finish line

See the source estate burn down by application, wave, owner, and dollar—not by slide-deck status.

For finance

A number worth chasing

Price every uncertified asset by day and turn decommission delay into a visible operating decision.

For risk & audit

Proof that survives the project

Keep who approved what, which evidence they relied on, and what changed after the verdict.

Designed to be easy to trust

Observe the estate. Never control it.

Read-only by design

Customer-owned roles grant only the inventory access each connector needs.

Short-lived federation

Per-tenant external IDs and temporary tokens replace stored cloud credentials.

Tenant isolation

Organization sessions resolve to database-enforced tenant boundaries on every request.

Coverage disclosed

Every report includes the evidence gaps—what our connectors could not see is shown, never hidden.

Stop funding yesterday

Your migration has a finish line.

Bring one completed wave. StackVolt will show what can be certified, what is blocking the rest, and what the delay costs.
