The SPO vendor that reports fees, gaps, and savings.
Most SPO vendors live inside the DSP. We live in your supply chain. ads.txt + sellers.json verification, schain fee analysis, and estimated savings — across 362K+ domains and 2,000+ SSPs.

Indexing 2,000+ SSPs across the supply chain
What you get
Three reports, one audit.
ads.txt + sellers.json Verification
Every line cross-referenced. Verified, unverified, mismatch, indeterminate — the four states DSPs check. We surface failures by SSP and severity.
Supply Chain Fee Analysis
Schain object decomposition. Intermediary hops, reseller chains, unauthorized paths. The hidden ladder of fees between buyer and publisher.
Estimated Revenue Impact
24% of ads.txt entries fail verification industry-wide. Authorized paths transact at 6x higher RPM. Translate your error count into recoverable revenue.
The savings math
Most publishers leave 5-15% on the table.
Industry-wide, 24% of ads.txt entries fail sellers.json verification. DSPs running SPO route around those paths. Authorized supply transacts at up to 6x higher RPM than unverified supply.
We translate your error count into recoverable revenue. Most publishers find more in the first scan than the $49/mo Starter plan costs over a year.

SPO vendor FAQ
An SPO vendor helps optimize programmatic supply paths via ads.txt, sellers.json, and schain analysis. Goal: cut hidden fees, eliminate unverified paths, concentrate spend on direct relationships.
