It’s late 2000. The world has survived the Millennium Bug and the Dotcom Bubble. And after more than a decade at an ad-industry giant, Luc van Beers is ready for a new agency. A new kind of agency. One that pairs strategy with creativity in the pursuit of high-impact corporate communications. That believes in growing through sharing knowledge, ideas, insights, opinions, trends and more. He finds a like mind in Tom Dorresteijn (today CEO of Studio Dumbar) and the two team up.

PROOF is born 2001. Lean, nimble, networked and creative. A small core team plus some of the best freelancers in the business. Focus on strategy with creativity for internal and corporate communications – because the best branding begins inside.

Success comes fast and the agency evolves. Over the years the slogan changes from ‘creative corporate communication’ to ‘corporate and internal branding’ to ‘reputation management’. Yet PROOF remains true to its roots throughout: lean, efficient, creative, strategic. Sharing knowledge, co-creating and collaborating, winning awards, reinventing the communications business, working greatly with the world’s great brands.

Fast forward to today and as an independent internal and employer branding agency we still work the same way. Inside out. Sharing. Combining insights and strategy with inspiration and creativity. Doing whatever it takes to tell a great story.
