Momentum Worldwide has added two top posts as the agency continues its global expansion.

Momentum promoted Kevin McNulty to worldwide chief marketing officer, a new post, and hired Michael Langton as executive VP-Asia Pacific regional director, also a new post.

The shop will name regional directors for Latin America and Europe/Middle East/Africa in the next few weeks, said CEO Chris Weil.

"As the regions have developed—especially Latin America and Asia-Pacific—we're looking to add a regional management structure to drive growth," Weil said. "Clients want more options globally."

McNulty had been chief growth officer and director of marketing & strategic planning for Momentum Europe/Middle East/Africa. He moves to Momentum's New York headquarters from the agency's London office, where he has overseen centralized planning and new business for pan-European clients American Express, Microsoft, Nestle, General Motors, CPW, Siemens and Intel.

McNulty also will oversee integration of Momentum's work with sister shops within McCann Worldgroup, including McCann Erickson Worldwide, MRM Worldwide, McCann Healthcare, FutureBrand and Weber Shandwick.

McNulty took the new post Feb. 1; he has been with Momentum since 1996, when sister shop McCann Erickson bought ad:vent, an agency McNulty founded, and folded it into Momentum.

Langton comes to Momentum from Wunderman, where he was Asia-Pacific president. Langton had earlier management stints at Bates Advertising and its now-defunct sibling Cordiant Communications Group in Asia Pacific, and at Young & Rubicam in South Africa and Australia. He began the new job Jan. 1, working from Momentum's Singapore office, overseeing offices in Japan, China, Indonesia, Taiwan, Australia, Thailand, Malaysia, and the Philippines. Asian-Pacific clients include Intel, Microsoft and Coca-Cola.

"The Asia Pacific region is an extremely fast growing and increasingly important part of the world. With Mike's leadership, I am confident Momentum will do in Asia what we've done in other parts of the world: to become the region's pre-eminent agency for events, sponsorships, promotions and retail marketing," Weil said.

Weil flattened out Momentum's management when he took charge in 2003, replacing the heads of shops that Momentum bought with direct-reports "so I could get to know the next generation of management," Weil said. "Now we're bringing up those new leaders."
