Keystone by Callisto Bridge™ · Patent pending

Every car has a Carfax. Every bond has a CUSIP. Every industrial asset has neither.

When a modular house, a battery pack, or a piece of factory equipment ships to a buyer, no shared record follows it. Its lender, insurer, inspector, and rating agency each rebuild the story from scratch. From the manufacturer's files. Then the vendor's files. Then the servicer's files. The same data, rebuilt over and over. That rebuild costs the industrial economy billions in wasted diligence, capital not deployed, and insurance not written.

Keystone is the missing layer. Every unit gets a signed, verified passport at the factory. A permanent record with a score. Banks read it to price loans. Insurers read it to bind policies. Program offices read it to release funds. Manufacturers, for the first time, own the data that decides the value of what they build.

If you're a lender advancing against 40% of a modular pool when the assets could support 60%, or an MGA whose finance team burns four weeks a cycle reconciling bordereaux, this is the layer that has been missing.
Pre-revenue and pre-customer, by design. Seeking 2-3 design partners this quarter. Keystone is data infrastructure, not a credit rating agency, MGA, or money transmitter. Every regulated action stays with a licensed counterparty that reads the record.

Two ways we work

Keystone is the infrastructure. Applied AI is how we help you use it (or use AI at all).

Most visitors come for Keystone. If you have a product that needs embedded AI capability without hiring an ML team, Applied AI is the sister offer.

How it works, in three steps

One record. Five downstream engines. Every buyer reads the same signed source.

  1. 1

    Ingest once

    Every physical asset your factory or program produces flows into the registry with its QA, inspection, resilience, and lifecycle data. Signed and hashed at insert. KeyScore 0–99 computed deterministically.

  2. 2

    Verify cryptographically

    Every state change (built, inspected, certified, installed, retired) appends an immutable event to the record. Any downstream auditor can verify the chain without trusting the operator.

  3. 3

    Sell N ways

    Lenders read Capital Rail. HFAs read Disbursement Rail. MGAs read Insurance Rail. Capital partners read Modular Index. Manufacturers monetize the registry itself. Every buyer pays per verified event.

Two outcome-defined ways to start.

Neither begins with a demo. Both begin with your data or your product, and both produce a written outcome you can use internally whether or not you continue.

Keystone · Six-week paid pilot

Bring 25–100 anonymized asset records.

We will show you what the registry, scoring, and downstream outputs (pool grade, disbursement gate, insurance pricing) would look like for your data. Written outcome brief. Preferred production pricing.
