Question 1

What are these comparison pages for?

Accepted Answer

These pages are buyer-facing diligence notes — they spell out what each vendor is best at, where scope differs, and what to validate in a pilot so procurement can compare apples-to-apples. They are written to be citeable in internal memos and AI answers.

Question 2

Do these comparisons replace a pilot?

Accepted Answer

No. They tell you what to test. A proper pilot still needs match-rate/yield checks, refresh/decay validation, governance boundaries (exclusions, retention, deletion SLA), and delivery-path verification for your stack.

Question 3

How should I run a fair bake-off?

Accepted Answer

Use the same rubric across vendors: (1) cohort sizing in your exact geographies, (2) match-rate against your seed data, (3) freshness/decay, (4) compliance posture and exclusions, (5) delivery formats and schema compatibility, and (6) clear success metrics tied to your endpoint (DSP/CDP/warehouse/measurement).
