The Problem

You know what you spent.
Not how it got there.

Between your DSP bid and the publisher's page, there's a supply chain. It has layers, intermediaries, and unauthorized paths — and most teams are flying blind on all of it until performance slips.

No supply visibility

DSP reporting shows where you served — not the full chain that got you there or the cleaner routes you missed.

Reseller tax on every hop

Each intermediary takes 15–20% before your dollar reaches the publisher. Direct paths exist — you just can't see them.

No common metric

Without a single efficiency grade, comparing allowlists, tracking progress, and aligning stakeholders is guesswork.

The Platform

Four capabilities.
One supply graph.

Everything is built on a single living data layer — 65K+ publishers, 2,500 SSPs, updated daily. Each tool draws from the same source of truth.

01

Publisher Intelligence

Discover premium inventory across the open web. Filter 65K+ verified publishers by GEO, SSP partner, IAB category, relationship type, and quality tier. Every publisher is classified using IAB taxonomy — so you can target by vertical with precision, not guesswork. See exactly who has a direct relationship with which SSPs before you plan a campaign.
