The agency that decided advertising works better when you can walk into it - building live events, sponsorships and immersive experiences for some of the world's biggest brands.
MOMENTUM WORLDWIDE · Global experiential agency, founded 1987 · Headquartered at 300 Vesey Street, New York City · Photographed here by its own mark - the "M" that has fronted brand moments on six continents.
The Business
Momentum Worldwide sells something most advertising agencies only gesture at: the moment itself. Where a traditional shop makes a thirty-second spot or a banner, Momentum builds the sponsored stadium activation, the branded retail takeover, the product launch you can touch. Its own summary of the job is short - "we create the experiences that make brands matter."
The firm was founded in 1987 and grew up inside the Interpublic Group network, absorbing event and promotion shops like Ad:vent and Louis London along the way. By 2000 it already ran roughly 58 offices and 1,650 staff. Today it operates from more than 30 offices worldwide, with a headcount reported between roughly 1,300 and 2,000 depending on the source, out of a New York headquarters at 300 Vesey Street.
What clients buy is not a logo on a banner. They buy a reason for people to care in person - and, increasingly, the data and measurement to prove that the caring translated into business. Momentum groups this work under a deliberately human label: "B2H," or Business2Human, its way of insisting that behind every B2B or B2C purchase is an actual person having an actual experience.
In practice that means a portfolio spanning brand activation, sponsorship and partnership consulting, experiential commerce, field marketing, celebrity and talent management, cultural strategy and proprietary experience-measurement tools. It is less a single product than a full stack for turning a brand into a place, an event, or a story people participate in.

Who Uses It
Momentum's customers are enterprise and Fortune 500 brands that need to show up in the physical world - across technology, financial services, CPG, automotive, healthcare and retail.
The Problem It Solves
Digital media made it cheap to reach people and hard to move them. Momentum's answer is presence: a moment a person chooses to walk into, remember, and share.
The bet is that empathy and loyalty scale faster through experience than through a headline - and that the resulting data closes the loop for clients who need to justify the spend.
How It's Different
Momentum competes with experiential specialists like Jack Morton, George P. Johnson, Octagon and Wasserman. Its edge is scale plus measurement - and a willingness to experiment, like staging an Alzheimer's-awareness simulator inside Fortnite. The illustrative mix below shows where its center of gravity sits versus a typical broadcast-first agency.

Expertise & Leadership
Global CEO Donnalyn Smith spent more than three decades at Momentum - regional director, managing director, group account director, then President of North America - before taking the top job in November 2022. That depth is the agency's real expertise: producers, strategists, technologists and creatives who have staged brand moments at scale, repeatedly, under real-world constraints.
"The modern-day experiential agency."
Where It Fits
Momentum sits in the experiential tier of the advertising industry - the part of the business that money can't fully automate. Holding companies own the media buying, the data platforms and the creative networks; live experience is the piece that still needs people who can build a physical thing on a deadline in a city where nothing goes as planned.
For most of its life that home was Interpublic Group, where Momentum operated alongside McCann and other network agencies on integrated accounts. In 2025 the ground shifted: Omnicom acquired IPG, and Momentum became part of the larger of the two remaining advertising giants. For a specialist in a durable, hard-to-commoditize capability, a change of parent matters less than the demand for the capability itself - and live experience has kept clients coming.
Two consecutive years as Campaign's US Experiential Agency of the Year (2024 and 2025), plus an Adweek Team Visionary award in 2025, suggest the work is landing. So does the willingness to try formats nobody has a template for - building an Alzheimer's-awareness simulator inside Fortnite for the Spanish federation CEAFA, letting players feel a simulated version of the disease rather than read about it.
