Decision pages that explain what each vendor is best at, what to validate in a pilot, and how procurement can compare apples-to-apples.

Comparisons FAQ
Common questions about how to interpret vendor positioning and how to run a clean procurement evaluation.
- What are these comparison pages for?
- 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. Use them in internal memos and RFP annexes.
- Do these comparisons replace a pilot?
- 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.
- How should I run a fair bake-off?
- 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).
