Research-Backed Opportunity

Australia's Property Data is Trapped.
Here's the $200M-$500M Opportunity to Free It.

CoreLogic and PropTrack hold Australian property data hostage behind closed enterprise contracts. There is no developer-friendly API. The US solved this years ago. Australia hasn't. Yet.

Every proptech startup in Australia hits the same wall
CoreLogic and PropTrack control property data in a closed, expensive duopoly. A startup wanting to build a property investment tool needs to negotiate a $50K+ annual contract before writing a line of code.
🔒

$50K+ Just to Start

No self-serve option. No free tier. No sandbox. Multi-month enterprise sales cycles, NDAs, and minimum annual commitments before you can access a single property record.

"A startup wanting to build a property investment tool needs to negotiate a $50K+ annual contract with CoreLogic before writing a line of code." -- Industry analysis, 2026
🗑

Fragmented Across 4+ Sources

Listings on Domain. Valuations from CoreLogic. Sales from state registries. Suburb stats from ABS. Council records in 50 different formats. Nobody has unified this.

"Integration nightmare: >50% of property managers say integrating new tech is their #1 challenge." -- PropTech industry survey
🚧

Zero Developer Experience

No REST API docs. No OpenAPI specs. No SDKs. No webhooks. Developers are reduced to screen-scraping listing sites or buying stale CSV dumps. It's 2026 and this is the state of play.

"22.7% of AU rental properties are self-managed with zero dedicated software." -- ABS / PropertyChat forums
The US already solved this. The playbook is proven.
Multiple companies built exactly this product for the US market. They raised hundreds of millions and got acquired. Australia has nothing equivalent.

ATTOM Data

US
Acquired

158M property records, 9,000+ attributes via API. Acquired by Roper Technologies. Became the backbone of US proptech -- every major real estate startup uses them.

HouseCanary

US
$206M raised

API-first automated valuation models for 136M properties. Sells to lenders, insurers, investors. Exactly the developer-first approach that Australia lacks.

Cherre

US
$130M raised

Real estate data unification -- normalizes data from 100+ sources into a single API. The exact model needed for Australia's fragmented landscape.

BatchData

US
Growing fast

Developer-friendly property data API with simple per-record pricing. Free tier for developers. The exact pricing model that makes property data accessible to startups.

The moat isn't technology. It's access.
There are structural reasons why no one has built this yet. Each one is an obstacle -- and an advantage for whoever solves it first.
1

CoreLogic/PropTrack Duopoly

They've locked up data supply relationships with state land registries. Exclusive licensing deals make it hard for new entrants to access the same raw data.

2

State-by-State Title Systems

Each Australian state has a different land title system, different data formats, different APIs (or no APIs at all). Normalizing this is genuinely hard engineering work.

3

"Too Small" for US Companies

Australia has ~11M properties vs US 158M. American data companies won't bother localizing. That means whoever builds the AU version owns it.

4

Massive Untapped Public Data

State land title registries, council planning/DA data, ABS census, rental listings -- enormous public property data that nobody has unified. The data is there. Nobody has done the work.

This isn't just research. I've built working infrastructure.
Working code, not slide decks. A CoreLogic sandbox integration, canonical data model, and an MCP server that lets Claude and ChatGPT query property data natively.

CoreLogic Sandbox Integration

Working authentication and data retrieval from CoreLogic's API. Property lookups, comparable sales, and suburb analytics flowing through a normalized pipeline.

Canonical Data Model

Unified schema that normalizes property data across different sources into a single, consistent format. Addresses, transactions, valuations, attributes -- all standardized.

MCP Server for AI Agents

A Model Context Protocol server that makes property data natively callable by Claude, ChatGPT, and any MCP-compatible AI. The future of data consumption is AI-first.

REST API Architecture

Clean endpoint design, authentication, rate limiting, and response schemas designed and partially implemented. Ready for production buildout with the right team.

mcp-property-lookup.ts
// MCP tool — callable by Claude/ChatGPT
export const propertyLookup = {
  name: "property_lookup",
  description: "Get AU property data",
  async execute({ address }) {
    const data = await propstack.get({
      address,
      include: ["valuation",
        "comparables", "suburb"]
    });
    return data;
  }
};
Claude Response
Based on PropStack data, 42 King St Sydney
is a 2-bed apartment valued at $1.31M,
up 8.2% in 12 months. Suburb median
is $1.18M with 6 comparable sales nearby.
I can build the technology. I need someone who knows the industry.
The technical infrastructure is proven. What turns this from a project into a company is someone with property data industry connections.

Looking for a co-founder who has:

Deep relationships in the property data ecosystem. Someone who's been inside the machine and knows where the cracks are.

Ex-CoreLogic / Ex-PropTrack

You've worked inside the duopoly. You understand the data licensing landscape, the gaps in their coverage, and what customers actually want that they can't get.

Ex-Domain / Ex-REA Group

You've built on top of property data at scale. You know the integration pain, the data quality issues, and the market segments that are underserved.

Real Estate Data Veteran

You've worked in property valuations, land registries, or proptech infrastructure. You have relationships with state data providers and know how licensing actually works.

Let's explore this together. Build together from day one.

What I Bring

Technical Co-Founder

Working CoreLogic integration. Canonical data model. MCP server. REST API architecture. Full-stack engineering capability to ship the product from prototype to production.

What You Bring

Industry Co-Founder

Data licensing relationships. Industry credibility. Access to early customers. Knowledge of where the bodies are buried in property data distribution in Australia.

flexible equity split. Let's explore this together.

If you become the API that proptech startups build on, you have the strongest moat in tech: infrastructure lock-in.

Let's Talk

If you have property data industry experience and this opportunity resonates, I want to hear from you. No pitch deck required -- just a conversation.
