Data Infrastructure That Accelerates Proptech Innovation
Focus your engineering team on building differentiated features while we handle data operations, compliance, and infrastructure across all markets.
Data solutions for Proptech Innovation

Unified Data
Access
Access both MLS listing data (4M+ active listings) and property data (160M+ property records) through coordinated APIs. Pre-matched via Constellation ID (CID) for seamless integration between listing and property information.

Reduced Implementation Time
Most customers are production - ready within days rather than the typical 3 - 6 weeks timeline. Pre-built integrations and existing MLS relationships eliminate procurement delays.

Managed
Operations
Data ingestion, normalization to RESO standards, quality assurance, and compliance management are handled by our team. Your engineers focus on product development rather than data operations.

Consistent Data Model
Work with a normalized schema across all data sources. Property attributes, codes, and structures are standardized, reducing development complexity and improving reliability.

One Partner. Every Data Layer.
Work with a single team for MLS feeds, tax records, parcel data, addresses, geocoding, and ownership information instead of managing multiple vendors.
