GroundTruth Tech Stack

Location and purchase-data driven advertising with in-store visit measurement

Advertising Services New York, NY 201–500 employees Founded 2009 Privately Held

GroundTruth runs a location-based ad platform that targets campaigns using real-world behavior data and measures whether consumers visit stores or websites. Its stack is data-engineering heavy (Spark, Hadoop, EMR, Glue, Iceberg, Airflow on AWS, with Redshift and Athena), fitting large-scale location data processing. Current hiring tilts toward finance, with pain points around invoice controls and tax errors, which points to back-office tightening rather than product expansion.
