Independent agency selection & partnership advice
Partnerships that perform, and keep performing.
Independent judgement. Proportionate process.
Mosaic helps brands find, appoint and retain better-fit agency partners. We advise on agency selection and pitches, media agency reviews, incumbent validation, relationship resets and ongoing partnership health.
The Mosaic View
Agency relationships are commercial assets.
They deserve the same care, discipline and attention as every other important investment in the business. Most agency relationships do not fail. They drift. Small misalignments go unnoticed. Many organisations invest months in a review, only to discover the relationship needed improving, not replacing.

Mosaic doesn't begin with a process. It begins by asking whether one is needed at all.
How Mosaic Works
One system. Four ways to apply it.
Agency relationships need different things at different moments. Mosaic helps you understand what is happening, improve what is worth keeping, find a new partner when change is needed, and sustain what is working.

Why Mosaic
Independent enough to stay objective. Experienced enough for the decisions that matter.
Mosaic combines senior practitioner judgement with the structure and governance clients expect from larger consultancies, without the overhead, process or bias towards unnecessary pitching.

“Mosaic helped us make a confident decision without creating unnecessary process. The approach was practical, proportionate and focused on strengthening an important partnership rather than defaulting to a pitch.”
