Every data source. One audience.

Your CRM. Your pixel. Your customer match list. LiveRamp's IdentityLink. Experian's lifestyle segments. TransUnion's TruAudience for CTV. Atrium blends them into one deduplicated audience, then activates that audience natively on every platform you run.

No more building the same audience five times in five different ad managers. No more wondering why your Meta lookalike performs differently from your Hulu segment.

Native activation

Built once. Active everywhere.

Audiences in Atrium aren't a separate database — they're pushed 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 once in Atrium. The change ripples to every platform within minutes.

Privacy by design

Your data stays yours.

Atrium is a clean room. PII is hashed before it ever leaves your environment. Customer lists are stored in a SOC 2 vault. Spend data, performance metrics, and audience definitions are never used to train shared models or surfaced to other advertisers.

You bring the data. Atrium does the plumbing. The competitive edge stays with you.
