Our Mission

To empower organizations by providing seamless connections between digital behavior and real-world actions, enabling smarter decisions, fostering innovation, and ensuring regulatory compliance through ethical data practices.

Unlike traditional data providers, GSDSI specializes in transforming complex, high-volume signals (from mobile app usage and location movement to media exposure and transaction logs) into activation-ready intelligence.

What Sets Us Apart

We don't just collect data. We curate, validate, enrich, and deliver it in formats that are immediately actionable. Our multi-source approach fuses location, digital behavior, media exposure, and transactional signals into a unified intelligence layer.

Every dataset carries full provenance documentation, consent verification, and compliance attestation, giving our clients confidence that their data foundation is built on trust.

The GSDSI Difference

Privacy First

Every dataset is built on consent-based collection with IAB TCF-compliant CMPs. We don't just comply with regulations. We lead with ethical data practices.

Signal Over Volume

We prioritize high-fidelity, actionable signals over raw data volume. Multi-layered validation ensures every data point meets quality standards.

Global Reach, Local Precision

From dense urban centers to emerging markets, our datasets support coverage across 150+ countries while maintaining granular local accuracy.

Continuously Refreshed

Most feeds are updated daily with 1-3 day latency. Historical data back to 2019 enables trend analysis and backtesting.

Enterprise-Grade Security

TLS 1.2+ in transit, AES-256 at rest. Delivered via Snowflake, BigQuery, AWS S3, Azure, or secure API endpoints.

Dedicated Partnership

Every client gets a dedicated account team, custom data configurations, and ongoing support tailored to their use case.

About GSDSI FAQ

Straight answers about GSDSI's history, locations, buyer verticals, and compliance posture. See also our general FAQ or contact the team.

When was GSDSI founded and what does GSDSI stand for?
GSDSI is Global Source Data Solutions Inc., founded in 2018 in Fort Lauderdale, FL. The company launched as a privacy-safe data intelligence provider bridging digital behavior and real-world signals, and has since expanded to serve enterprise, federal, defense, and adtech buyers across 150+ countries.
Where is GSDSI headquartered?
GSDSI is headquartered at 3410 Galt Ocean Dr., Fort Lauderdale, FL 33308. The company operates globally but centralizes data engineering, federal solutions, and enterprise licensing out of the Fort Lauderdale office.
What industries and buyer personas does GSDSI serve?
GSDSI licenses data to advertising and media agencies, tech and MarTech platforms (DSPs, SSPs, CDPs), streaming and CTV platforms, global and national brands, location-based marketers, financial services firms, real estate investors, healthcare life sciences teams, and federal defense and intelligence agencies. Each vertical has a dedicated account team and use-case playbook.
What privacy certifications does GSDSI hold?
GSDSI aligns with GDPR, CCPA/CPRA, and state privacy laws including TDPSA and Oregon, Colorado, Florida, and Maryland requirements. International transfers from the EEA, UK, and Switzerland rely on Standard Contractual Clauses with supplementary measures where appropriate. The company is IAB TCF aligned. All location data excludes sensitive categories per the ODNI CAI Policy Framework (2024).
What makes GSDSI different from SafeGraph, Placer, or LiveRamp?
GSDSI combines multi-source fusion (location, CTV/ACR, identity, B2B, CPG, property) rather than specializing in a single data layer. The Euclidean Feed deterministically links mobile ad IDs, CTV exposures, and consumer behavior into a unified identity graph. Full provenance documentation, consent verification, and compliance attestation ship with every dataset, so procurement and legal sign-offs move faster than with single-source competitors.
