The Growth Marketing apprenticeship is focused on running a 360° marketing process for Marble:

• Campaign Execution: Plan, launch, and monitor performance-driven marketing campaigns (organic and paid) across Google Ads, LinkedIn, and X to drive measurable user acquisition.

• A/B Testing & Optimisation: Constantly test ad copy, landing pages, and creative assets to lower our Cost Per Acquisition (CPA) for both talent and portfolio interest.
