THE WHOLE THING IN ONE SENTENCE

Marketing finds a property. Sales wins it. Estimation prices it. Design draws it. Pre-Con clears it. Construction builds it. Finance pays for it. Contract Admin defends it. Handover closes it. Vestra warranties it. The Tenant App lives in it. One property record from start to forever.

THESIS

Why HOP exists.

EVERYONE ELSE

Project-centric

The project is the root. When the project closes, the data evaporates.

Procore
Buildxact
Buildertrend
Sitemate
PlanRadar
Lose the warranty clock. Lose the maintenance history. Lose the property when ownership transfers.
HOP

Property-centric

The property is the root. Every event, doc, photo, certificate, defect, warranty clock attaches to a property_id.

Record carries through warranty
Survives ownership transfer
Tenancy + maintenance history
Next build appends, doesn't restart
Insurer-grade cohort data
This is the moat. It cannot be retrofitted.

EXECUTIVE OVERLAY

Cross-cutting.

High-level cash flow only — no nuance.
CTO
Derek
Zar
Owns HOP itself. D1, Workers, R2, KV. Every integration. Reviews any feature that risks breaking property-as-root.
DASHBOARD
System health + high-level cash position.
LEGAL
Caleb

REAL HANDOFFS

The silos don't queue.
They talk.

The lifecycle is the happy path. The value is in the cross-silo flows that don't follow the queue.

01 Cam's deal → Mariana's ECI (04) → Zee's BOQ (03) → Caleb's live contract (08) One deal record. Four owners. One property anchor.
02 Mariana stamps a plan (04) → Caleb's audit gate fires (08) → Drazen / Simon / Malcolm get fresh drawings on Bluebeam (06)
03 Caleb locks a site start (06) → Zee's RFQ deadline alerts fire (03) → Suppliers called up immediately
04 SM invoice queue (06) → Caleb sign-off (08) → Alex / Nigel approve (07) → Maria pays it (07)
05 Daniel's QA at PC (06 → 09) → Vestra ticket created (10) → Paul's maintenance schedule picks it up (11)
06 Tristan's CEO heatmap ← schedule (Caleb) · budget (Zee/Freddie) · quality (Daniel) · safety (SMs) · margin (Nigel/Alex)
THE POINT

These aren't integrations between separate systems. They're queries against the same property record.

CORPORATE WRAPPER

Cordon owns the IP.
Op cos run the work.

Cordon is the parent IP-holding entity (renamed from IPCO). Op cos pay licence fees monthly. Cordon pays R&D invoices in cash within 30 days.

PARENT · IP HOLDING
Cordon
Co-founded Tristan (CEO) · Stefan (CFO) · Derek (CTO)
Holds all IP. Receives monthly licence fees from op cos. Pays R&D invoices in cash within 30 days. RDTI claimant. "At risk" defence holds because cash genuinely moves.
OP CO · BUILDER
Hillbrook Projects
Existing builder. Customer one. ACN 152 218 304.
OP CO · PLATFORM
HOP newco
Runs Vestra + Tally. Property-record substrate.
OP CO · ADVISORY
Angel Advisory
Stefan's consulting practice. Not a HOP product.
OP CO · FUTURE
Angel Soft + Financial
Sibling ventures. Not HOP products. Fin/Prop/RegTech.
IMPORTANT

The Angel suite are sibling op cos under Cordon, not HOP products and not HOP silos. HOP's product family is Vestra and Tally. Do not conflate.

hop
The land under the build.

Vestra rides on it. Tally rides on it. Cordon owns it. The property record is forever.
