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.
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.
Listings on Domain. Valuations from CoreLogic. Sales from state registries. Suburb stats from ABS. Council records in 50 different formats. Nobody has unified this.
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.
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.
API-first automated valuation models for 136M properties. Sells to lenders, insurers, investors. Exactly the developer-first approach that Australia lacks.
Real estate data unification -- normalizes data from 100+ sources into a single API. The exact model needed for Australia's fragmented landscape.
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.
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.
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.
Australia has ~11M properties vs US 158M. American data companies won't bother localizing. That means whoever builds the AU version owns it.
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.
Working authentication and data retrieval from CoreLogic's API. Property lookups, comparable sales, and suburb analytics flowing through a normalized pipeline.
Unified schema that normalizes property data across different sources into a single, consistent format. Addresses, transactions, valuations, attributes -- all standardized.
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.
Clean endpoint design, authentication, rate limiting, and response schemas designed and partially implemented. Ready for production buildout with the right team.
Deep relationships in the property data ecosystem. Someone who's been inside the machine and knows where the cracks are.
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.
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.
You've worked in property valuations, land registries, or proptech infrastructure. You have relationships with state data providers and know how licensing actually works.
Working CoreLogic integration. Canonical data model. MCP server. REST API architecture. Full-stack engineering capability to ship the product from prototype to production.
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.
If you have property data industry experience and this opportunity resonates, I want to hear from you. No pitch deck required -- just a conversation.
