Liz Rutgersson joins Assembly Global as Chief Executive Officer

Assembly Global has appointed Liz Rutgersson as Chief Executive Officer, giving her responsibility across the agency globally and in North America as the business enters its next phase of growth.

Liz joins Assembly Global after 16 years at dentsu, most recently serving as CEO of iProspect North America. She brings more than 20 years of experience across brand building, strategy, digital media, analytics and search optimisation, with experience working with major global brands.

Her appointment comes as agencies continue to rethink how media, technology, data and creativity come together for clients.

Leading Assembly Global's Next Chapter

As CEO, Liz will be responsible for driving Assembly Global's growth, strengthening client partnerships and leading the agency's global and North American operations.

Her appointment comes at a time when clients are increasingly looking for agency partners that can bring together media, technology, data, creativity and commerce rather than operate those capabilities in isolation.

Liz's experience across agency leadership and performance marketing gives her a background closely aligned with that changing environment.

Building an Agency for the Future

Liz has spent her career working across an industry undergoing significant structural change.

In sharing her move, she said she has built her career around the belief that there is a better way to build agencies and that the industry is ready for change.

That perspective will now shape her leadership at Assembly Global, where she will work with the agency's teams, clients and partners to build on its existing capabilities while challenging established ways of working.

Challenging Traditional Agency Models

Liz highlighted Assembly Global's people, clients and ambition as key reasons for joining the business.

She described the agency's team as a group of curious and clever builders and said it was immediately clear that there was an opportunity to create something the industry wants and needs.

The approach reflects a wider shift in the agency sector, where clients are seeking more integrated partnerships and greater accountability for business outcomes.

Backed by the Stagwell Network

Assembly Global operates within the broader Stagwell network, giving the agency access to a wider range of resources, capabilities and expertise.

Liz pointed to the strength of that network and its leadership as another part of the opportunity ahead.

For Assembly Global, the connection to Stagwell provides a broader platform as the agency continues to develop its global capabilities and respond to changes across media, marketing and technology.

Growth in a Changing Media Landscape

The advertising and media industry is undergoing significant change as AI, automation, data and evolving consumer behaviour reshape how brands engage their audiences.

For agencies, those shifts are creating demand for new operating models and more connected approaches to marketing.

Assembly Global's next phase will take place against that backdrop, with Liz bringing experience across digital media, performance marketing, analytics and agency transformation to the role.

A New Chapter at Assembly Global

Liz described her first day at Assembly Global as the beginning of a new chapter and said she is excited about what the team can build together.

Her arrival adds experienced agency leadership at a time when the industry is questioning traditional models and exploring how technology can reshape the relationship between brands and their agency partners.

With responsibility across global and North American operations, Liz will now lead Assembly Global as the agency looks to build on its foundation, strengthen client relationships and develop an agency model designed for the future.
