Crowder is renowned as a fearless disruptor of the traditional agency model and has a successful track record as a suit and no-nonsense client-whisperer at some of the country's top agencies, according to the agency.

"I'm thrilled at the opportunity to work on the Positive Dialogue team and be a part of the DUKE group, which is breaking new ground in South Africa's advertising and marketing industry with its integrated approach, progressive vision and culture — combined with a steady pragmatic business results focus," says Crowder.

"Despite the tumultuous times, the three best-of-breed agencies that form the DUKE Group are thriving on an unfaltering growth path and have consistently proved their value to their impressive client base. The levels of collaboration and sheer expertise between Positive Dialogue, digital marketing specialist Mark 1 and Duke are unmatched," adds Crowder.

"It's exciting to step into the role of Positive Dialogue's managing partner and to head up our integration in the group and together build on the success with our new account wins," Crowder says.

The DUKE group was formed in response to disruptions in the global business environment and fast-changing consumer behaviours, which have rendered many traditional advertising and marketing models and practices obsolete, the group says. The three independently owner-managed agencies, all award-winning in their fields, have come together to help brands find success in challenging times.

Positive Dialogue's managing director Tracy Jones says, "As a seasoned brand builder and communicator, Crowder has driven some of the most memorable campaigns in the country. Having worked closely with him for more than a year, it's fantastic to bring his skillset in-house. He brings such a deep understanding of today's consumers, what interests them, what they value, what spurs them into action and how best to have great relationships with them."

"Crowder's insights and expertise are a great asset to our team and we are looking forward to a phenomenal year with our clients delivering forward-thinking, locally-relevant campaigns that drive real growth," concludes Jones.
