How it works

At the heart of our initiative lies an automated tool that compares ads.txt files with sellers.json and provides simple, useful feedback, as well as our Wizard that allows you to automatically clean up your file.
We based the tool on our extensive knowledge and experience with the AdTech industry and our passion for transparency.
Helping publishers and buyers gain insight into the authenticity of the parties who mediate between them.
We promote transparency to curb the fraud that is casting a shadow over the AdTech ecosystem.
