Why We Built the
HomeSelf Protocol
Real estate is broken. Not the buildings - the system connecting buyers to sellers. We built something better.
The Problem
Real estate is stuck in the past. Property portals charge commissions that add nothing. Agents gatekeep information that should be public. Trust is manufactured through paid reviews and premium placements.
In an age where AI can process millions of data points in seconds, why do we still rely on human intermediaries?
The answer: the old system benefits from opacity. The less you know, the more you pay.
Intermediation is Software
The middleman served a purpose when information was scarce. Today, both problems have technological solutions.
AI can analyze photos to detect features. OCR can extract data from documents and validate against public registries. Natural language models can answer questions 24/7 in any language.
This isn't about replacing jobs. It's about removing unnecessary friction.
Data Sovereignty
When you list on a traditional portal, you surrender your data. They own it. They monetize it.
HomeSelf inverts this model. Your property data belongs to you. The protocol simply provides a standardized format for expressing it.
Ownership Comparison
- Portal owns your data
- You pay for your own leads
- Delisting doesn't delete data
- You own your data
- Direct communication
- Full control over visibility
Trust as Computation
In the old world, trust was a marketing budget. The more you paid, the more "trusted" you appeared.
HomeSelf computes trust. Every listing has a Trust Score based on verifiable inputs.
AI-to-AI Markets
The future is AI systems negotiating on behalf of their principals. Your personal AI knows your budget, preferences, and schedule. The property AI knows the listing inside out.
They meet, exchange structured data, negotiate terms, and present you with options that actually match your needs.
This is why we obsess over data structure. Why we publish AnswerPacks. Why we expose machine-readable APIs.
The protocol introduces the concept of a Verified Property Record (VPR) — a standard unit designed for AI-readable property data.
"I need a 2-bedroom in Rome with balcony, under €450k, suitable for a family relocating from Milan, with verified ownership documents"
Your seeker AI queries VPRs. Each property's VPR responds with verified data. No phone calls, no portal scraping, no uncertainty.
Protocol, Not Portal
HomeSelf is not another property portal. It's a protocol - a set of standards for representing and exchanging real estate data.
Portals lock you in. Protocols set you free. Anyone can build on top of HomeSelf. Any AI can consume our data.
Our Commitment
- Open API access for all AI systems
- Public documentation of all data formats
- Transparent trust computation
- Zero commission on transactions
- Owner control over all data
The Web of the Future
The web is shifting from pages written for humans to structured records readable by AI. Your VPR is a structured record that AI systems can discover, understand, and match.
We're building for this transition.
What Makes It a Protocol
HomeSelf is not just another interface. It's a protocol because the data structures and machine-readable formats come first.
Protocol-Level Guarantees
- VPR as Machine-Readable Record
Every property is a structured data entity that AI systems can parse without scraping HTML.
- Agents Can Negotiate via A2A Handshake
AI-to-Agent state machine enables autonomous negotiation without human chat intermediaries.
- MCP Tools Enable Agent Execution
Model Context Protocol integration lets AI agents directly search and retrieve property data.
