Ketel One is offering today’s gentlemen the awesome opportunity to showcase their game-changing ideas with “A Gentleman’s Call: In Pursuit of an Idea that Matters.”

A Gentleman’s Call is a nationwide search to invest behind one original idea that champions the lifestyle of the modern gentleman. Ketel One is looking for substance and style within an idea, inspiration or endeavor that will raise society’s behavioral bar. You can get involved at www.agentlemanscall.com, where the five projects best exemplifying a higher standard of thinking and living will be selected. The Grand Prize Winner will be chosen by consumers across the country.

Ketel One will then invest $100,000 to turn the winner’s idea into a reality.

To lead this nationwide call-to-action, Ketel One has enlisted the mentorship of three men that embody the essence of a modern gentleman: actor and philanthropist Ian Somerhalder, Co-Founder and CEO of the Movember Foundation, Adam Garone and celebrated actor Carlos Ponce. These cultural counselors will be defining the values of the ultimate gentleman’s competition through their day-to-day lives.

Entries close on July 29, 2012. Visit www.agentlemanscall.com for complete contest rules and to submit a project.
