Foursquare bake-off: location diligence checklist

Vendor comparison: A buyer guide for location intelligence, POI, and mobility data procurement.

TL;DR

  • Choose GSDSI when POI polygon fidelity, brand hierarchy mapping, and post-FTC mobility diligence are core requirements.
  • Choose Foursquare when your primary requirement is a location-tech platform and your org is standardized on its ecosystem.
  • In a pilot, validate: polygon quality, visit attribution rules, consent posture/exclusions, and geography-specific panel density (not global numbers).

What matters most in 2026

Location data procurement has shifted: the winning vendor documents consent posture, enforces exclusions, and proves panel density and accuracy in your exact geographies, not just the largest deck numbers.

Decision frame

Choose GSDSI when

  • You need polygon-based POIs (not just centroids) for dense retail and multi-tenant environments.
  • Brand-to-parent hierarchy is required for rollups (share-of-visit, competitor overlap).
  • You need mobility panel diligence with enforceable sensitive-category exclusions.

Choose Foursquare when

  • Your org is buying a location platform + tooling ecosystem more than discrete datasets.
  • The operational motion is platform-first and already integrated into your stack.
  • Your use case is satisfied by the platform's standard POI + visitation abstractions.

Location buying guide

Pilot checklist

  • POI quality tests: polygon fidelity, centroid placement, duplicate handling, multi-tenant disambiguation.
  • Panel density: daily unique devices in your DMAs/polygons, and stability over time.
  • Accuracy filtering: how low-accuracy pings/VPN artifacts are suppressed.
  • Compliance artifacts: consent provenance, exclusions, retention, deletion SLA.

FAQ

What changed in location data procurement after FTC enforcement?
Buyers now need documented consent posture, enforceable exclusions for sensitive categories, and geography-specific panel density and accuracy proof. Large “panel size” numbers without these controls are not sufficient for procurement.
How do I test POI quality?
Test polygon fidelity in dense retail, multi-tenant disambiguation, brand-to-parent hierarchy mapping, and closure/opening freshness. Bad POIs create biased visitation and attribution.
What is the fastest pilot to run?
Pick a set of known POIs in your markets, run polygon/visit attribution tests, validate daily unique devices and stability, and audit the compliance artifacts (exclusions, retention, deletion SLA).
