Who uses these tools
19 publishers where we found evidence that at least one of these tools is live. Select a tool to see who runs it.
How we know: we read each publisher's ads.txt file (the public list of companies allowed to sell its ad space), load its homepage and record the vendor scripts it actually runs, and log press releases, vendor case studies and editorial research that name the publisher. Articles that mention a tool never count. A publisher found in two independent sources is confirmed; one source is marked single source.
| Tool | Publishers found | Small | Mid-market | Enterprise | How found |
|---|---|---|---|---|---|
10 | 1 | 3 | 6 | Site code + published | |
4 | – | 1 | 3 | Site code + published | |
2 | – | – | 2 | Published | |

ads.txt and site-code checks cover every publisher we track, while press and editorial evidence only finds deployments someone published, so compare tools found the same way. Resold inventory (ads.txt reseller lines) is not counted. 5 publishers are seen in one source only and not yet confirmed by a second.

Identity & Matching Quality: The system matches first-party identifiers against partner data sets with high accuracy and minimal data loss rates during the process.

Then ask each vendor for two publisher references at your size and a written first-year cost including implementation.
