With the help of an international community of volunteers, Eyeo develops open source software that millions of people use every day to have a better online experience. Its solutions such as Adblock Plus, which, with over 300 million downloads, is the most popular add-on/extension ever, put users in control over the kind of content they see online. Beyond that, the company builds software that encourages positive, informative advertising, and privacy protection practices. Eyeo is an international team, about half of whom work in the main Cologne office and the other half remotely. Eyeo was founded in 2011, when Till Faida met Wladimir Palant; and the two decided to take Palant’s sometimes hobby, Adblock Plus, and try and change a billion-dollar industry with it.
