sadstxt.com started as a side project. I needed a subset of the ads.txt aggregate file for another project. Unwilling to pay thousands of dollars to IAB, I started crawling the data myself.

Recognizing others need access to this data as well, we decided to make our data widely available. sadstxt.com is now live. You can browse and analyze ads.txt data at no cost.

If you are looking for additional services related to ads.txt implementation, please get in tough. We are currently looking for a few ad exchanges to join our pilot program as we continue to build out these premium features.
