Iwan is publishing the award winning +3 Magazin as a supplement to the Frankfurter Allgemeine Zeitung and Süddeutsche Zeitung. The readers of +3 Magazin can contribute their opinions on three questions that are printed on the cover. Their answers then get published nationwide next to the answers of three established experts (e.g. politicians, managers, scientists).

The publishers of the Warum Verlag, Iwan and Robert Willmann, met while working as project managers in an international publishing house. They were in charge of the production of independent supplements in German national newspapers.

As digital natives they strongly felt that today's newspapers do not meet contemporary requirements. "Instead of mainly delivering information, a contemporary newspaper rather showcases different opinions on such", Iwan states. Robert adds: "Most importantly these opinions are not solely those of the editorial staff."
