BrandMyItem is a marketplace for physical ad space. Post the item you want (a phone, a laptop, a golf bag, a carry-on). Brands reserve spots on it. When every spot is taken, we buy the item new, apply the branding, and ship it to you. Yours at delivery, you never pay. Brands get what a screen can't give them: a real object, carried into coffee shops, airports and meetings every day, with photo check-ins for the whole term.
Your company gets a skyscraper in a live 3D city. Every dollar raised makes it taller. Raise the most and the entire city becomes your ad: every billboard, the blimp, the banner plane, the cars, all running your logo until someone outraises you. Half of every dollar funds the charity you choose.
