Brown will become the company’s Executive Chairman. 

Posnanski’s entrepreneurial drive led to him found avVenta, a pioneering digital agency that was acquired by Accenture Interactive (now Song) in 2012. Posnanski became a senior executive, responsible for growing the agency’s content, digital media, personalization, CRM, commerce and marketing operations, helping to build the Division into a $12B digital agency.

His strategic vision and proven leadership skills, combined with his wealth of experience and integrity make him the ideal person for this role.

Not only has Jamie helped clients address the most complex marketing challenges on a global scale, but he also has first-hand knowledge of what it takes to successfully bring a company at our stage of development through the next phases of growth.

I am looking forward to supporting Jamie as we grow our global presence and build more expansive and innovative services for our global client base.”

With the addition of PWC’s media unit and now with the R3 acquisition, I believe we are incredibly well positioned to help clients fuel growth by optimising returns across an even broader scope of media and marketing investments.”
