About The Position

Prolific is not just another player in the AI space — we are the architects of the human data infrastructure that is 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. Our Sales and Success team works with a broad range of enterprises and emerging AI labs to power their most critical data and model development initiatives. As an Enterprise Customer Success Manager, you will partner with a diverse book of enterprise customers — from large organizations building their own ML pipelines and AI agents to smaller AI labs scaling their research programs — ensuring they achieve meaningful, lasting value through our human data offerings. In this role, you will drive adoption, consumption, and expansion through a land-and-expand motion, acting as a trusted advisor across research, program management, and business stakeholders. You will own the end-to-end success lifecycle, guiding customers from onboarding to maturity, expansion, renewal, and advocacy while collaborating with your counterparts on Prolific's Services, Support, Sales, Solutions Engineering, Product, Marketing, and other teams.
