Challenger Brand Marketing® is not like traditional marketing. If you implement traditional marketing strategies and lack the financial resources to sustain those programs at the same level as your larger competitors, your marketing efforts will likely fall short.

As a full service branding, advertising and interactive agency, we think of successful marketing as a smooth-running machine, with all its components working together in harmony to maximize results and return on investment. It all starts with a proven system that eliminates guessing, reduces risk and assures success. Gumas’ proprietary Challenger Brand 5-Step ProcessTM helps you effectively compete against better-resourced competitors and stretches your marketing resources.
