The AI-powered trust engine for real estate.
The data behind every real estate decision lives in thousands of places, assembled by hand every time someone needs it. Cornerstone Data Studio does it once, so every person and property has a standard, traceable, governed record in a single place.
Connected to 1,000+ property, identity, and financial data sources across North America, through direct integrations and AI agent collectors.
Every source has its own way of naming data. The Studio renames each field into a common language for real estate portfolio management. Currently at 3,000 fields and counting.
Real estate data is full of mistakes. Different AI models check each other's work: is this the right field, and does the value make sense? Low-confidence answers go to a person.
The source travels with the data. Every field is stamped with where it came from, when it was collected, and the checks it passed.
The Studio provides the property, identity, and financial data needed for a real estate decision or transaction. These governed records together become the verified portfolio.
You hold data homeowners need. Put it on the Studio and reach them through every application built on it — governed, attributed, and earning.
