Ad Fontes Media

The company operates a content and data subscription model built around a proprietary dataset of media-source bias and reliability ratings. It creates value by systematically evaluating news and media outlets, encoding those assessments in a structured database, and presenting the results through visual charts, interactive tools and applications that are understandable by non-experts. Value is delivered to individuals and institutions that need to assess or teach about media bias, integrate bias and reliability scores into products, or benchmark sources.

Revenue is generated by selling recurring subscriptions for enhanced access to the interactive bias database, charging for licences to use chart assets and data in educational or commercial contexts, and offering institutional site licences for larger user bases such as school districts and libraries. Historically it has also used crowdfunding and mission-driven investment to finance product development and expansion, but ongoing value capture is primarily through subscriptions and licensing.

Ad Fontes Media is a US-based public benefit corporation focused on rating the political bias and reliability of news and media sources. Its core asset is a human-analysed database of outlets and content that is exposed through a visual “media bias chart”, an interactive web platform, and a mobile app, with periodic flagship chart editions also distributed as PDFs.

The company generates revenue primarily from paid subscriptions that unlock enhanced access to its interactive bias/reliability database, licensing of chart assets and data to institutions and commercial users, and education and institutional site licences. Its paying customers include individual news consumers, educators, libraries, school districts and other organisations that require structured media-bias and reliability information for media literacy, research, or integration into their own products and curricula.
