WKZ stands for co-op advertising funds (Werbekostenzuschuss): money or budget that a brand makes available to its distribution partners for advertising. The classic proof of use is a screenshot and an invoice, which is time-consuming for both sides and hard to verify.
ViralSpoon Connect logs which partner published which brand content. This turns proof of use into a byproduct of everyday use. For brands with co-op advertising programs, that's real added value.
