Cannonball was started by a small group of St. Louis advertising agency veterans united in their belief that great ideas, a strong work ethic and a general lack of ego would result in something special. Today, Cannonball has grown up to be a full-service, people-focused branding agency that delivers actionable ideas. Our mission is brand impact. And we have decades-long experience in advertising, sales promotion, retail and online activation. Nimble. Tireless. Imaginative. And nice. Really.
