An Audience Passport is a certificate of measurement for a publisher's audience: who is actually there, how many are human, and how many resolve to real, named people — read from independent instruments on the property itself, never modeled to look better than the data. Empty panels stay empty. Every claim carries its source, method, basis count, and a grade: verified, modeled, or not measured.
Fixed eight-panel skeleton: audience scale · identity resolution · humanness (tier 1, FouAnalytics) · professional composition · demographics · geography · acquisition sources · claims ledger. A machine-readable JSON twin ships alongside every document for agentic buyers. Format v0.3 draft.
A passport is issued to the publisher and delivered as a private link. It is theirs to share with sponsors, agencies, and buying agents as they see fit — we do not publish a client registry. The sample below is our own property, shown so you can see the instrument before commissioning one.
Every passport's persona panel is executable. Publishers can offer sponsors a pre-flight test: the sponsor's creative is run against the audience's modeled archetypes before budget is committed, returning receptivity scores, objections, and a per-dimension read. Clearly labeled as the modeled layer — the passport certifies, the pre-flight explores.
