Ad Fontes Media

Ad Fontes rates the news for reliability and bias. We're on a mission to positively transform media and society.

Our data is used by all stakeholders in the media ecosystem, including advertisers, publishers, ad tech companies, researchers, academics, educators, and individual citizens.

We have products and services to help advertisers confidently invest in highly reliable, minimally biased news while avoiding misinformation and extremely polarizing content. We also help publishers improve, showcase, promote, and monetize their high-quality journalism through third-party audits and technology tools.

Ad Fontes Media is incorporated as a Public Benefit Corporation (PBC) in Colorado.
