Ad Fontes Media

The business combines proprietary media analysis with multiple packaging layers. A public-facing chart builds awareness and trust; subscription products monetise consumers and institutions; enterprise data products license scored datasets and metadata into advertising, analytics, and research workflows; and service lines monetise the methodology through publisher certification, consulting, and workshops. Value is created by turning editorial analysis into reusable datasets, trust signals, and decision support tools for both media buyers and media owners.

Ad Fontes Media is a private media intelligence company and public benefit corporation that analyses news sources and content for political bias and reliability. Its best-known product is the Media Bias Chart, a consumer-facing reference and subscription product, but its commercial business extends into enterprise data licensing, publisher audits, and advertiser-focused media planning and brand suitability solutions.

The company makes money through a hybrid model: subscriptions for individuals and educational users, enterprise licensing for its data platform, and managed or consulting services for advertisers, publishers, and organisations. Its paying customers span brand advertisers, agencies, ad tech platforms, publishers, educational institutions, researchers, and organisations seeking media literacy training or publisher certification.
