eyeo

eyeo operates a two‑sided ecosystem around ad‑filtering. On one side, it distributes free browser extensions that block or filter online ads for consumers, using community filter lists and the Acceptable Ads standard to determine which formats can pass through by default. This builds a large user base that controls a significant volume of ad impressions.

On the other side, it offers publishers, retailers and advertising clients commercial participation in the Acceptable Ads programme and related allowlisting services. Large entities that benefit materially from having their compliant ads shown to ad‑filtering users pay licence or allowlisting fees, generally structured as a share of incremental revenue attributed to allowlisting. Through Blockthrough, it extends this model with publisher monetisation and recovery tools that help digital media businesses regain revenue otherwise blocked, creating value by reconnecting advertisers and publishers with hard‑to‑reach ad‑filtering audiences while preserving a user‑controlled filtering framework.

eyeo GmbH is a German software company best known as the maintainer and commercial operator behind major browser ad‑blocking extensions and the Acceptable Ads standard. Its products block or filter online advertising for hundreds of millions of users while enabling selected non‑intrusive ads to be shown under defined criteria.

eyeo generates revenue by charging large publishers, retailers and advertising clients licence and allowlisting fees to show ads that comply with the Acceptable Ads standard to users of its ad‑filtering products. Following its acquisition of Blockthrough, it also provides publisher‑side technology to recover revenue otherwise lost to ad blocking, positioning itself as an intermediary between ad‑filtering users and digital media businesses.
