MCI joins forces with Coulter Companies

Merger to create world's largest engagement and activation company

Geneva, 9 March 2015. The MCI Group, the world’s largest international provider of strategic engagement and activation solutions, has merged with US-based Coulter Companies, which serves associations and other not-for-profits and corporations through its award-winning Coulter and Agency Coulter business units.   

Coulter and Agency Coulter now become MCI’s scalable growth platform in the United States, delivering the following capabilities:

  • Strategic association management, meetings and consultative services focused on building and engaging communities.
  • Sophisticated work with global corporate brands focused on business activation and engagement of target audiences.

The merger further accelerates MCI’s ability to work global and deliver local to senior influencers and decision-makers in associations, corporations and governments.  The union of MCI and Coulter Companies results in a truly global brand of more than 1,800 professionals in 60 cities and 31 countries, more than double the size and reach of its nearest competitor.  

“MCI has been active in the US market for many years”, says Sebastien Tondeur, CEO of MCI Group.  “About 10% of our revenues come from US-based clients and our management has held key leadership positions in many US-based industry associations, including ASAE, MPI, PCMA, SITE and the AMC Institute. With the addition of Coulter Companies to our group, we can now activate a robust strategic and operational base in the US, making us the first truly global company in our industry.”

“This merger is more than just a geographic or business expansion, it represents a union of aligned cultures and shared outlooks on the global market”, said Coulter Companies CEO Thomas Coulter Gibson.  “It will be thrilling to see the affirmative impact of this union on our clients and professionals, current and future.” 

MCI is a key driver of innovation in the international meetings, events, association and congress industries.  Coulter Companies and its clients will immediately benefit from MCI’s global network and expertise in strategically engaging and activating target audiences.

Coulter and Agency Coulter will continue to operate under its brand names, though as MCI Group companies, with all Executive leadership remaining unchanged.
