Eyeo is the company behind the world's most popular browser extension: [Adblock Plus](https://adblockplus.org/). It maintains Adblock Plus versions for Firefox, Chrome, Opera, Safari and Internet Explorer; also standalone Adblock Plus applications for Android and iOS as well as [Adblock Browser](https://adblockbrowser.org/) for Android and iOS. Almost everything that the company does is open source, and the primary directive is delivering great products that will improve the web as a whole. In order to achieve our goal of creating a sustainable web ecosystem we developed the [Acceptable Ads program](https://acceptableads.org/). Mediating between user and publisher interests, providing the former with a good web experience and allowing the latter to retain revenue sources, is a complicated task and we don't always make friends. However, we feel strongly that this is an important task to be done, and we've already achieved significant successes.
