Client Partner

Client Leadership Team Overview

The Client Leadership Team at Open Partners is the heartbeat of our agency - driving strategic vision, integration and performance through close, high-impact relationships. We blend Media, Creative and Data into cohesive, growth-oriented roadmaps and set the tone for Smarter, Faster, Better across everything we do. This is a privileged team of top-tier talent with drive and ambition who partner with clients to drive true business value and define and demonstrate what Agency of Next means.

The Client Partner is a central leadership role within the Client Leadership track, responsible for owning client relationships, leading strategy, and driving commercial growth.

You will lead integrated strategy across media, data and creative, deepen senior client relationships (including decision-makers and emerging Champions), and own the commercial performance of your portfolio. Client Partners are expected to set the standard for how OP shows up: strategic, commercially-minded, relationship‑led and relentlessly committed to excellence.
