Clean Room

Combine data across companies. Share only the results.

Each party contributes through its own source. Analysis code that every party approved runs over the combined data, and only outputs that pass the joint policy are released.

02 · Use case

Campaign measurement between advertiser and publisher

Who it's for: Brands, agencies and publishers.

Today

Advertisers want to know whether a campaign reached their customers and led to sales. Publishers know who saw the ads. Answering means matching the two customer lists, which neither side is willing, or allowed, to hand over.

With Clean Room

Each side contributes its list through its own sealed source, and both approve the measurement code before it runs. The code matches the lists inside attested nodes, and only aggregates that pass the joint policy, such as reach and conversions per campaign, come out.

What you get

  • Reach and conversion measured on real customer matches
  • No customer list leaves either company
  • A receipt for every released result, for both sides

03 · How it works

Four steps, all inside attested nodes.

  1. 01 · Contribute

    Each party sends its data through its own sealed source.

  2. 02 · Approve

    Every party approves the analysis code before it runs.

  3. 03 · Analyze

    The code runs over the combined data inside attested nodes.

  4. 04 · Release

    Only outputs that pass the joint policy come out, with receipts.

04 · Built in

What it inherits from the engine.

Clean Room runs on the same confidential engine as every Calimero product, so it comes with the same proof.

  • Attested hardware. Clients verify the node's image before sending anything.
  • Sealed end to end. Nobody, including us, can read data inside a sealed node.
  • Signed receipts. Every answer can be checked offline, later, by anyone.
