Your mission:

As a Client Growth Manager, you will own a portfolio of North American clients and serve as their primary strategic partner. Your focus: drive measurable revenue growth, deepen client relationships, and consistently unlock new scale opportunities through cross-sells and up-sells.

• Enjoy building long-standing customer relationships. 
• Are energized by the evolving ad tech world, are adaptable, and thrive in a fast-paced dynamic team.

Your day to day activities to enable customer growth include monitoring the performance of user acquisition, retargeting & CTV campaigns, collaborating closely with Sales & Ad Operations teammates to ensure alignment with client goals and performance, and spotting opportunities to expand and scale budgets. 

More about what you will do:

• Own and grow a portfolio of direct clients and agencies across diverse verticals, with clear accountability for revenue expansion, retention, and relationship health.

• Lead high-value client touch points: run weekly/bi-weekly check-ins, share performance insights, set next steps, and build confidence through consistent, proactive communication.
• Identify and activate growth opportunities: anticipate client needs, propose upsell/cross-sell solutions, and leverage Smadex capabilities to expand spend.
• Serve as the voice of the client internally: escalate blockers early, collaborate with Sales, AdOps, Product, and GCE teams, and ensure smooth execution across workflows.
  Produce and present strategic reviews including QBRs, wrap-ups, and post-mortems with clear recommendations and data-driven insights.
