Control before commitment.

The Controller sits between your business and every financial commitment it makes. It reads contracts before anyone signs, validates invoices before anyone pays, and routes every decision through the approval chain you've set.

Built on Mustang.

Measured in your spend.
Not in benchmarks.

94%

Out-of-policy and over-budget requests stopped at intake. Before they reach legal or finance.

5x

Faster from vendor request to signed, approved contract.

30%

Reduction in off-contract spend within one quarter.

Zero

Payments made outside your approval chain

Most finance tools record what already happened.

The Controller governs what you sign.

 Inside your walls.

Four gates.
Every commitment passes all of them. 

Organised around how commitments actually move: from a vendor request through contract, approval, invoicing, and obligation. Each gate has one job. Nothing advances without it.

Closed doesn't mean done

Every commitment logged with a full trail. Renewals, price changes, billing anomalies, and payment deadlines watched from the moment you sign. You're told before they hit.

The right person. Not the nearest person

Checked against your budget and policy. Invoices matched to their purchase orders. Everything routed through the right approval chain for the amount and category. Nothing signed or paid off-policy.

Read before you sign

Terms extracted. Risk surfaced. The money, the term, the lock-in, the exit, the clauses your business won't accept. The short version, with the dangerous parts flagged. 

The front door

Every vendor and contract request enters here, not someone's inbox. The vendor is vetted against your approved supplier list. The request is scoped before anyone spends time on it.

 Every gate runs on your rules. Not a generic policy template. Because The Controller runs on The Grip.

From request to signed.
Governed at every step.

The request enters

Vendor and contract checked against The Grip before anyone else sees it.

The contract is read

Terms, risk, and budget validated. Out of policy: stopped here.

The approval routes

Right person, right amount, right chain. Nothing signed or paid without explicit sign-off.

The record closes

Signed version logged. Obligations, renewals, price changes, and billing anomalies watched.

Your people approve at every gate. The Controller never signs.

Your contracts. Your invoices. Your spend data. Your audit trail. Nothing leaves.

Your cloud, your data center, or air-gapped.

No public AI reading your contracts or your terms.

No third-party model touching your spend data.

Your permissions, your perimeter, your policy.

Built for procurement that cannot send its terms out of the building.

Fits the systems money already runs through.

ERP and finance

AP and payments

Contracts and e-sign

CRM. Salesforce, Hubspot.

Storage

Start with The Controller.
The rest of Mustang starts warm. 

Every contract, every vendor, every rule feeds back into The Grip

When you add The Planner, it already knows your approval chains. When you build a custom agent for legal or finance, it starts with your vendor history and compliance regime already loaded.

Bring us one month of contracts.
We'll show you what we'd catch. 

Two weeks against your actual contracts, your actual approval chain, your actual spend. A quantified baseline before you commit to a dollar. 

That's the only way we start.
