Partners in The&Partnership
Partnership is at the heart of everything we do.
It is what drives us Further, Faster
Towards seamless integration, with core marketing capabilities working together in lock step. Towards bespoke collaboration, with tailored teams driving agile, responsive ways of working. And ultimately towards true transformation of the marketing operating model, delivering pace & scale.
Being different to our competitor set has been the driver of our success.
As a joint venture between independent agency network The&Partnership and GroupM, backed by WPP, we offer our clients the best of both worlds. The transformational pace of creativity, partnership and integration that comes from our independence. Coupled with the transformational scale of investment, talent and purpose that comes from being fully backed by GroupM’s trading, tech & innovation scale.
GroupM is the world’s leading media investment company.
Responsible for more than $53B in annual media investment, delivered through agencies Mindshare, EssenceMediacom, Wavemaker and mSix&Partners.
We also work differently: we build bespoke, collaborative teams around what clients actually need, powered by deep partnership.
These range from media-only teams that work in direct partnership with clients’ own in-house performance functions, all the way to fully integrated teams across data & tech, commerce, media, creative and content automation.
Any of these bespoke teams can be embedded into our clients’ own marketing teams & offices. This way of working has allowed us to spearhead the evolution of the agency operating model.
