A Managed MLS Data Layer for Modern Prop tech
GroundTruth Layer gives proptech teams a dedicated, continuously maintained MLS data environment with fast search, maps, and AI-ready access—so they can build products without wrestling MLS complexity or running ingestion pipelines.
A Real-Time MLS Data Platform Built as a Primary Data Layer
Each customer operates against a dedicated, managed MLS data environment that stays continuously synced and behaves like a primary data layer. Teams query live MLS data directly in production—without ingesting feeds, rebuilding databases, or maintaining MLS sync infrastructure.
This is not a request-per-page API. It is a managed MLS data foundation you can build on.
Platform Model (Not IDX)
GroundTruth Layer is not an IDX solution and does not grant IDX display or redistribution rights.
The platform is designed for teams that already hold MLS authorization and need a reliable, extensible technical foundation for approved MLS use cases. GroundTruth Layer operates as a technical subcontractor and data processor, supporting customers’ MLS workflows rather than acting as a data distributor.

How Teams Use GroundTruth Layer
Teams treat GroundTruth Layer as their MLS data layer. Applications query live listings for search, map experiences, analytics, and AI workflows without managing ingestion jobs, cache invalidation, or MLS churn.
Updates, removals, photos, and corrections are handled continuously behind the scenes—so teams can focus on product instead of plumbing.
