Co Founder

Current
Greenadz Gmbh & Co. Kg

Hamburg Area, Germany

With GreenAdz, Dr Sandra Gärtner and her husband, software architect John Sasse-Gärtner, are making market research "green": GreenAdz is a sustainable and highly responsive recruitment and incentivisation approach that allows users to be surveyed at digital touchpoints in a more appreciative way than via traditional pop-up survey invitations: Always unobtrusively integrated and incentivised with a TREE: For sustainably better results, better samples and happier users for just €1 per survey participant. This sustainable incentivisation concept is so successful, particularly in influencer marketing research with Gen Z, that not only the influencer facts and various campaign-accompanying advertising impact studies are implemented by Greendz and incentivised with trees, but also B2B-decision-makers love to take part in surveys and plant a tree with their answers. www.greenadz.de
