McCann is an advertising agency that has sat atop a large hill in Prague’s Riegrovy Sady since 1996. Since then, the company has grown into one of the largest, most creative, and most effective agencies in the Czech Republic. It has earned the title of "Most Effective Agency of the Year" multiple times, collected numerous Cannes Lions — including gold and bronze — and even secured a Grand Effie. McCann believes that true success and growth are only possible when its clients succeed as well.
