Overview

Power programmatic activation, cross-channel measurement, and closed-loop attribution with GSDSI's privacy-safe data feeds. We help agencies, DSPs, and brand marketers connect digital and CTV ad exposure to real-world outcomes, proving true campaign ROI across every screen.

GSDSI (Global Source Data Solutions Inc.) powers adtech, agencies, DSPs, and brand marketers with a privacy-safe stack spanning ~200M+ U.S. MAID-to-HEM identity pairs, 700M+ international devices across 150+ countries, ~13-14M monthly CTV IDs from ACR panels, and the Euclidean Feed for deterministic exposure-to-outcome attribution: all sourced consent-verified and IAB-taxonomy aligned for programmatic activation. The advertising technology ecosystem demands data that bridges the gap between digital campaign delivery and real-world business outcomes. GSDSI provides the connective tissue: privacy-safe data feeds that support programmatic audience activation, cross-channel measurement, and closed-loop attribution from impression to store visit. Our MAID Feed provides ~200M+ U.S. MAID-to-HEM linkages (with 700M+ international device reach across 150+ countries) from consent-verified sources, enriched with behavioral and interest signals for programmatic activation across major DSPs. The CTV/ACR Feed captures smart TV viewership data for cross-screen audience measurement and frequency management. The Euclidean Feed deterministically links mobile, CTV, and purchase signals into a unified consumer graph for true multi-touch attribution that connects ad exposure to offline conversions. Agencies and brand marketers use these feeds together to prove that their campaigns drive incremental foot traffic, quantify the real-world value of CTV investment, and optimize media mix allocation based on observed outcomes rather than modeled estimates. All data is sourced through consent-verified channels with IAB taxonomy alignment for activation readiness across programmatic platforms while maintaining compliance with GDPR, CCPA, and platform-level privacy frameworks.

Frequently asked questions about Advertising & AdTech

How do adtech and martech platforms typically use GSDSI?

As supply for audience marketplaces, as identity-graph inputs for cross-device resolution, as third-party-data overlays for first-party DMPs and CDPs, and as enrichment for measurement and attribution products. Activation pivots are HEM, MAID, IP, and household ID, designed to weather cookie deprecation.

Does GSDSI license data into DSPs and SSPs?

Yes, directly to DSPs and SSPs, and via the major third-party-data marketplaces. Licensing terms cover redistribution rights, revenue-share or fixed-fee structures, and use-case constraints. Standard MSA terms are available for review during procurement.

Can GSDSI provide identity for CTV-specific use cases?

Yes. The CTV/ACR feed (~13-14M unique CTV IDs per month) joins to the household-level identity graph, supporting cross-screen reach, frequency capping, addressable activation, and attribution workflows for adtech buyers and measurement vendors.

How does GSDSI handle cookie deprecation and ATT impact?

By weighting toward identifier types less impacted by browser and OS changes (HEM, postal, household ID) and by explicit support for clean-room and consent-driven activation patterns. The catalog is intentionally diversified across identifier types.

What pricing models are available for adtech licensors?

Annual data-license deals with revenue-share and minimum-guarantee structures, fixed-fee batch deliveries, and per-API-call DaaS pricing for live identity-resolution use cases. Pricing is typically below top-tier identity-graph competitors at comparable match rates.
