What Campaign's Power 100 marketers reveal about the future of internal teams, hybrid models and agency partnerships.

As more of the world’s most influential brands bring marketing capabilities in-house, the question is no longer whether to in-house, but how. Drawing on insights from Campaign’s Power 100 marketers, this article explores the very different ways brands are building internal teams — from creative and social to data, media and production — and the strategic reasons behind those choices.
What emerges is not a single blueprint, but a spectrum of hybrid models. While speed, control and data ownership continue to drive in-housing, external agencies remain critical partners for scale, specialism and fresh perspective. With contributions from senior marketers and recruiters — including The Industry Club’s Zoe Edwards — the piece captures an industry in transition, where in-house capability is evolving rapidly, and no two brand set-ups look quite the same.
