Neustar bake-off: identity spine vs graph feeds

TL;DR

• Choose GSDSI when you need licensed identity and outcome feeds with documented decay fields and multi-channel joins.
• Choose Neustar when your organization standardizes on their identity spine for onboarding and measurement across partners.
• In a pilot, compare match yield, link-type mix, and governance, not a single blended match-rate slide.

Identity spine vs feed bundle

Neustar is frequently the system-of-record for resolving IDs across partners. GSDSI is frequently the supplier of underlying linkages and adjacent signals (CTV, mobility, clickstream) that your team joins in-house.

Decision frame

Choose GSDSI when

• You need MAID→HEM, household, and CTV identifiers with last_seen decay in your warehouse.
• You are running a multi-vendor measurement or activation stack and need feed-level contracts.
• You want pilot metrics tied to your seed file, not a vendor-provided benchmark only.

MAID feed · Identity resolution hub

Choose Neustar when

• Your enterprise already routes onboarding and attribution through their identity APIs.
• Changing the spine would require re-integrating multiple downstream partners.

Pilot checklist

• Join yield on your CRM or exposure seed, segmented by channel.
• Deterministic vs probabilistic link mix disclosed per field.
• Opt-out and deletion propagation tested on a change-delta file.
• Delivery path and schema stability across two refresh cycles.

FAQ

Does Neustar replace MAID→HEM feeds?

Often no. Neustar may be the identity spine across partners while GSDSI supplies linkages and adjacent signals you join in your environment.

What proof beats a deck match-rate?

Join yield on your seed, link-type mix, last_seen decay, and opt-out propagation on a change-delta file.
