Litmus
Media quality controls, deployed where decisions happen.
Litmus turns media-quality policy into clear, measurable decisions for buyers, sellers, and platforms.

One policy, four control points
Quality is not a single score applied after the fact. Litmus puts the right decision at each stage of the media transaction.
- Seller pre-bid
Pre-bid containers
Apply explicit quality criteria before inventory enters the transaction stream, with eligibility and exclusions visible at the source.
- Curation
Curated packages
Assemble media against documented standards so buyers can understand what qualifies, how it was selected, and what evidence supports it.
- Bidder decisioning
Filters & no-bid containers
Turn quality policy into repeatable bid and no-bid decisions without forcing every bidder to reconstruct the same logic independently.
- Post-bid
Measurement pipelines
Connect transaction decisions to delivery and outcome data, then use the evidence to monitor drift and improve upstream controls.
02Data architecture
A feedback system, not a blacklist
Every control produces decision data. Litmus connects that evidence across stages so quality standards can be explained, tested, and improved rather than treated as a static list.
- 01
Define
Translate quality principles into explicit, inspectable criteria.
- 02
Decide
Place each filter or container at the point where it can change the transaction.
- 03
Observe
Record what qualified, what did not, and why the decision was made.
- 04
Improve
Feed post-bid evidence back into criteria, packages, and decision logic.
03Engage
Design the control system
Start with the quality policy, the transaction stages you can influence, and the evidence already available. We can map the architecture and identify the first deployment.
