Happy Clients bringing new clients. The idea comes straight from this insight: a number of human interactive billboards built around town to let real clients dialogue with potential clients passing by. No filters, no bank involved, just a real questions/real answers game between real people. We asked real clients to be the actors of our ad because, to say it the ING way: “Our clients ARE our best advertising”. The first human billboards. Normal people asking, real clients answering.
