CDP - The Reinvention Agency. We believe that customer loyalty is a thing of the past. Competitive brands constantly pitch to your customers for their business in much the same way as agencies pitch to prospective clients. The reputation (and livelihood) of your brand is therefore under constant review. At CDP, we believe that the most effective way to garner and ensure customer loyalty under this intensive competitive pressure is by continually reinventing in order to maintain relevance, enhance consumer interest and expand market share.
