InnerGroup Taps Veteran James Sanderson as CEO to Scale In-House Marketing

NEW YORK, NY – April 13, 2026 – InnerGroup, a global in-house marketing operations company, has appointed James Sanderson as its new Chief Executive Officer. The move, which sees Sanderson succeed founding CEO Fred Schuster, signals a strategic shift for the company and the broader in-house marketing industry—a transition from establishment to optimization.

Sanderson, an industry veteran who has been at the vanguard of the in-house movement for years, steps into the role from his previous position as Global President, which he held since March 2025. His appointment is less a change of guard and more a calculated deployment of specialized expertise, aimed squarely at what many brands now consider their most pressing challenge: making their internal agencies deliver high performance at scale.

“James has been instrumental in shaping InnerGroup from the outset, bringing deep experience in building and strengthening in-house marketing operations globally,” said Robert Berkeley, Chairman of InnerGroup. “We’ve established a strong foundation and the business is seeing interest from brands across the US and Europe, with demand for structured in-house capabilities continuing to build. His appointment reflects our natural evolution into the next phase of growth, with the leadership, team, and client partnerships in place to execute.”

The Architect of In-House Operations Takes the Helm

Sanderson’s career is a roadmap of the in-house agency’s evolution. Before joining InnerGroup, he founded Wunderman Thompson Inside, WPP’s dedicated on-site agency offering. His leadership experience also includes serving as Chief Operating Officer of Oliver Agency, one of the most prominent names in the in-house space, and building the global creative operations practice for consultancy ICP. His extensive background is rooted in digital innovation, having helped establish one of the UK’s first digital agencies, DNA, in the late 1990s and later serving as Managing Director for the award-winning digital agency Glue.

This deep, hands-on experience in constructing and scaling internal marketing functions from within multiple agency networks makes him a uniquely qualified leader for InnerGroup's mission. His focus is not on convincing brands to bring marketing in-house, but on re-architecting the models they have already built to ensure they are fit for purpose.

“The in-house market is changing fast,” Sanderson stated. “Brands have been building internal agencies for years, but the question now is whether those agencies are structured to perform at scale. That is the problem InnerGroup solves. We’ve built the model, methodology, and team to deliver it. The focus now is on execution and growth.”

From Trend to Table Stakes: The New In-House Challenge

The landscape Sanderson describes is one of maturity and mounting complexity. The in-house movement is no longer a nascent trend. According to data from the Association of National Advertisers (ANA), 82% of its members had an in-house agency by 2023, a figure that has steadily climbed from just 42% in 2008. The conversation has shifted decisively from why brands should in-house to how they can do it better.

As these internal shops take on more responsibility—with 88% reporting increased workloads in the past year—new challenges have emerged. The initial drivers of cost savings and faster turnarounds, while still important, are now overshadowed by the need for operational excellence and strategic impact. Key pain points for brands include a persistent talent and skills gap, particularly in specialized areas like data analytics and media planning, and the struggle to manage workflows efficiently as volume and complexity grow.

Many in-house agencies that were built for speed and cost-efficiency are now straining under the weight of strategic expectations. This operational friction is precisely where InnerGroup, under Sanderson’s direction, aims to intervene.

An Adaptive Model for a Maturing Market

InnerGroup’s strategy hinges on its “Adaptive Marketing Operations” model, a two-pronged approach designed to diagnose and solve these structural inefficiencies. The first component, InnerAdvisory, functions as a consultancy, deploying a proprietary diagnostic tool called InnerAssessment to analyze friction points across eight key areas of a marketing organization. This allows the company’s advisors to provide a clear roadmap for improving organizational health and performance.

The second component, InnerStudio, acts as the execution engine. It is an offshore content creation and production unit that leverages the global infrastructure of its parent company, EKCS. This relationship provides InnerGroup with access to over two decades of experience and a 600-person team operating across ISO-certified production centers in the US, UK, Canada, India, and Australia. This global footprint enables 24/7, cross-platform production at a scale that many individual in-house teams struggle to achieve on their own.

This integrated model of advisory and production allows InnerGroup to not only identify problems but also provide the resources and manpower to solve them, offering a flexible, hybrid solution that complements a brand’s existing internal team.

AI as the Engine for Scalability

Powering this entire operation is Mediaferry®, a proprietary AI workflow platform that serves as the company's technological backbone. Originally developed as an internal tool within EKCS to automate its own complex workflows, Mediaferry was productized and launched to external clients in 2024, bringing a battle-tested solution to the market.

The platform is designed to inject efficiency directly into the creative production process. Its AI capabilities can generate project briefs from simple workflow notations, instantly assemble appropriate creative teams, and automate repetitive design tasks to accelerate campaign delivery. Features like SmartDesign AI help produce on-brand campaign assets in minutes, while the platform’s integrated management tools streamline everything from copy collection and approvals to performance tracking.

By combining expert human oversight from its advisory practice with the relentless efficiency of its AI-powered production studio, InnerGroup is positioning itself as a key partner for brands navigating the second, more difficult phase of the in-house journey. With James Sanderson, an architect of the movement itself, now leading the charge, the company is set to focus intently on delivering the structure and scale that modern marketing organizations desperately need.
