Every property has a keystone.

The one piece that holds everything together. On Keystone, that's verified data: who owns it, what condition it's in, and what it's honestly worth.

Property Identity

One passport. Every fact about the property.

A Keystone ID follows a property for its entire life, through every sale, renovation and owner. Buyers stop guessing. Sellers stop repeating themselves.

Keystone Property Identity

A permanent identifier tied to the erf, not the listing. It survives agents, portals and owners.

FAULT condition rating

Foundation, Access, Utilities, Legal, Title. Five checks, one honest letter grade a buyer can read in a second.

Keystone Valuation

Modelled from deeds transfers, municipal values and live market activity. Updated monthly, not on request.

Syndicated through PropCon

List once on Keystone and your property distributes to partner portals automatically. No duplicate admin.

Professional ecosystem

The people a property needs, in one place

Buying or selling pulls in a dozen professionals. Keystone registers them, rates them on completed transactions, and puts them where the property is.

Where this is going

Build. Launch. Prove. Expand.

Keystone ships in stages. Each one earns revenue before the next one starts, and the architecture is built from day one to carry all of it.

Same codebase, every phase

Next.js and Postgres with row-level security. Phase 5 does not require a rebuild of phase 1.

Phase 1 — Commercial launch Live now

The revenue foundation: a working property portal that people can list on and buy through today.

Phase 2 — Property Identity Q1 2027

  • Conveyancing workflow
  • Full stakeholder OS
Security & privacy

Property data is personal data

Keystone handles ownership records, identity documents and financial information. That is treated as a first-class engineering problem, not a policy page.

POPIA compliant by design

Explicit consent capture, purpose limitation, and a working data deletion path built into the schema.

Row-level access control

A seller sees their listing. An agent sees their mandate. Permissions are enforced at the database, not the interface.

Encrypted document vault

Title deeds, ID copies and compliance certificates stored encrypted at rest with signed, expiring access links.

Full audit trail

Every view, edit and export of a property record is logged and attributable. Disputes get answered with evidence.

Verified before published

Listings clear title and identity checks before they appear. Unverified listings never reach a buyer.

You own your data

Source code, database and customer records belong to Keystone. Export everything, any time, in open formats.

Put your property on the record

Listing is free. Verification takes about 48 hours. Your property keeps its Keystone ID for good.
