Programmatic
Supply Intelligence
See exactly how your budget moves through the supply chain, who's in the path, what they cost you, and the cleaner routes you're not using. Before you spend. While you're live. After the campaign closes.

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.
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.
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.
SSP Intelligence
Benchmark every SSP by publisher reach, vertical coverage, and geographic distribution. See which SSPs have direct relationships vs. reseller chains, and identify white-space opportunities your competitors might be using.
PathScore™
Upload an allowlist and get a 0–100 efficiency grade in under 60 seconds. See which domains route through resellers, what it costs, and which cleaner direct paths are available to swap in.
Campaign Analysis
Upload a DV360 or DSP campaign report and see a post-flight audit of every path your spend traveled. Which domains routed through resellers, what the leakage cost, and the cleaner alternatives for next time.
The industry's first pre-bid efficiency grade
A single 0–100 score that summarizes how efficiently your media dollars reach the publisher. Compare allowlists, track improvement quarter over quarter, and walk into any QBR ready to answer the question before it's asked.
