Describe the audience in plain English. Atrium resolves it against your first-party data, partner segments (LiveRamp, Experian, TransUnion), and the Atrium Tag — then activates it natively on every channel.
Write who you want to reach. Atrium blends your CRM, pixel, and customer match list with LiveRamp, Experian, and TransUnion — deduped and resolved against the Atrium Tag — into one audience, activated natively on every platform.
No rebuilding the same audience five times in five ad managers. No wondering why your Meta lookalike drifts from your Hulu segment.
Audiences aren't stored in a separate database. Atrium pushes them into each platform as native objects. Meta sees a Custom Audience. Google sees a Customer Match list. Hulu sees an Audience Match segment. The Trade Desk sees a 1st-party seed.
Update the prompt once. The change ripples to every platform in minutes.
Atrium is a clean room. PII is hashed before it leaves your environment. Customer lists live in a SOC 2 vault. Spend, performance, and audience definitions are never used to train shared models or exposed to other advertisers.
You bring the data. Atrium does the routing. The edge stays with you.
One prompt resolves your audience across every rail. Privacy by design.
