Private marketplace

A curated or invitation path to inventory, usually via deal IDs. Not the open remnant auction our first tests buy.

Published 2026-09-09 · Search job: private marketplace vs open exchange

A private marketplace (PMP) is inventory offered to a selected set of buyers, usually through deal IDs, sometimes with a floor or a package story. It is still programmatic. It is not "the open exchange." You target the deal. You do not spray remnant and hope a PMP appears.

Adprime Zero first tests run on open exchange. We have not published a judged PMP versus remnant flight on this product, so we will not invent a quality lift for PMPs. Child-seat deal use has been historically empty. If you already have a deal, trafficking it is trader work.

A PMP is not an IVT certificate and not a reason to skip click-to-page-view. Measure the path you actually bought.

If you are choosing a first $20/day cell, you do not need a PMP to start. You need a matching landing page and a prepaid wallet.

When you still want a trader

QPS traffic templates, deals, and a custom bidding agent are account-manager and trader work. Adprime Zero will not sell those as a Cursor prompt.

Run the next test from chat

Open an account, add prepaid budget, and let an agent create the campaign, rotate creatives, and read the report. No DSP setup, no insertion order, no sales call.
