Brands Navigating a Vast Agency Ecosystem
Brands face an expanding and diverse agency market and must balance fit, scalability and relationship quality when selecting partners. Data from Agency by Agency shows the UK agency sector has nearly doubled in ten years. Three consultants — Sophie Verachten, Luke Fleming and Rachel Said — identify core issues: finding agencies that truly understand brand positioning and can scale with channels; overcoming distrust after poor agency experiences and avoiding siloed delivery; and choosing value and compliance over lowest price in affiliate and partnerships. To help matchmaking, PI LIVE Europe and the Agency Advisory Board are building a free Agency Ecosystem Map directory, updated biannually, that will list agencies’ service types, territories, specialisms and accolades.
Practical industry resource and commentary about agency selection; useful to brands and agencies but not a platform-level policy or major technical release.

Brands and Agencies Build Strategic Partnerships
An ADWEEK House Cannes Lions group discussion (published June 29, 2026) explored how brand-agency relationships are shifting from transactional contracts to strategic partnerships based on trust, transparency and shared ownership. Panelists from Weber Shandwick, Unilever/Knorr, Bel Group/GoGo squeeZ, Luma AI, Doosan Bobcat, Kellanova and NewtonX discussed how agencies should move beyond deliverables to solve underlying business problems, the importance of long-term fit, and how AI is becoming an “invisible partner.” Speakers highlighted the need for open conversations and formal governance around agency use of AI, gave examples of agency-led AI pilots, and warned that lack of transparency about AI can damage relationships. The conversation emphasized collaboration, mutual accountability and aligning on outcomes rather than outputs.
