Signal is a full-service digital and CRM agency with over 200 people. They use data, code and creativity to help large organizations solve complex marketing problems. Signal is long on specialists but short on silos. The agency is the result of a merger of three highly specialized sister agencies. In the process, it has remade its agency model and its modus operandi from the ground up. It has none of the legacy culture, process or talent issues that have made integration a dirty word.
