CREDO says “I believe in D/C.”

CREDO Mobile, the San Francisco-based, social-change-oriented cell company that gives a portion of its customers’ charges to progressive causes, has given its marketing business to D/C. The agency had worked with CREDO’s parent company and predecessor brand, Working Assets, for more than 10 years, primarily on direct response. The new relationship, effective in late February, expands the relationship substantially to include strategic marketing, advertising, media planning and buying, as well as direct. Strategic marketing and advertising was previously with SS&K in New York.
