infrastructure that's reshaping the landscape of AI development. In a world where foundational AI technologies are increasingly commoditized, it's the quality and diversity of human-generated data that truly differentiates products and models. The role We're looking for a Head of Product Marketing to run product marketing as a discipline at Prolific. You'll own how we position, message, and launch our products and participant capabilities to AI and Research customers - packaging platform, participant supply, and services into coherent solutions that land across very different buying contexts. This is a player-coach role. You'll manage a team of three PMMs - each embedded in different parts of the business - while staying operational on the highest-stakes positioning and launches. You'll be the connective tissue between Product, Sales, and the vertical marketing teams, ensuring we speak with one voice about what Prolific does and why it matters. You'll need to operate across very different buying contexts: technical AI teams evaluating data integration pipelines, academics navigating data quality and funding questions, and enterprise buyers building business cases. If you're energised by growing a PMM function in a world of complexity, this will be a good fit.
