The Problem

Property Data Is Fragmented and Expensive

Every county in America stores property records differently. Legacy data providers charge $10K–$100K/year for bulk files you still have to normalize. Building a usable property data layer from scratch takes years and millions of dollars.

3,000+ County Formats

Every county records ownership, assessments, and transactions in its own schema. The same field has different names, types, and conventions everywhere.

No Unified Schema

Property records, transaction history, tax assessments, and risk data live in separate silos. Joining them requires massive entity resolution infrastructure.

Missing Enrichment

Raw records don't include flood risk, census demographics, opportunity zones, permit history, or code violations. You need 5+ additional sources for a complete property profile.

Enterprise Pricing

Legacy providers like ATTOM and CoreLogic charge enterprise minimums for what is fundamentally public data. Small teams and startups are priced out entirely.
