Brandvertisor is a display advertising marketplace that helps brands, CMOs, ad agencies, and website publishers build long-term ROI partnerships. It aims to address issues like fraud and lack of transparency in the digital advertising industry by offering a marketplace with a 5% commission where publishers can create profiles and advertisers can directly purchase ads. The $87 billion global display advertising market represents an opportunity for alternatives to platforms like Adsense. Brandvertisor has so far validated its model with over 5,000 website profiles and is seeking a $350,000 seed round to further develop its in-house supply-side platform and header bidding infrastructure.
