Clarke joined Adding Value in the part-time role in January after 11 years at P&MM.
"As my very enjoyable 12 months contract as director of strategy at Adding Value is due to come to an end in December, I am now excitedly looking to the future," said Clarke, adding that he believes there are still some fundamental gaps in agency offerings, which Purple Dog Solutions will look to fill.
"I have created what I hope to be a new agency approach: client-centric, confidential and dynamic in terms of the ability to scale up (or down) experienced event specific teams of all disciplines, as apposed to charging clients for an infrastructure that they may not require.
"My approach will be to assume that my corporate clients understand their business better than the agency does, with them safe in the knowledge that I will assemble and lead exceptional teams of professionals in order to manage and deliver their campaign."
"His knowledge and experience in meetings and incentive travel - together with his big black book and considerable number of accumulated air miles will set him in good stead as he ventures out on his own. We wish him every success."
Purple Dog Solutions will be open for business for events operating after December, when Clarke’s contract with Adding Value comes to an end.
