VP of Marketing in London

Prolific is not just another player in the AI space – we are the architects of the human data infrastructure that’s reshaping the landscape of AI development. In a world where foundational AI technologies are increasingly commoditized, it is the quality and diversity of human‑generated data that truly differentiates products and models.

This is a rare opportunity to shape a category‑defining marketing engine for a platform at the forefront of AI. You will lead how Prolific is positioned and adopted by frontier AI labs and enterprise customers, while continuing to scale our research business and global participant ecosystem. At a pivotal stage of growth, this is a hands‑on leadership role. You will define and execute a clear, commercially‑driven marketing strategy that strengthens our enterprise B2B motion, sharpens our market positioning, and drives pipeline and revenue.

You will build, evolve, and lead a globally distributed team across the full breadth of marketing, including enterprise B2B (core focus), product marketing, brand, growth, and marketing operations – alongside B2C growth for our participant ecosystem. This role requires a balance of strategic thinking and execution: someone who can operate at a high level while also rolling up their sleeves to build, test, and scale what works.

Responsibilities

• Set and execute an integrated marketing strategy aligned to company goals, with a strong focus on enterprise B2B growth.
• Build, restructure, and scale the marketing organisation, including team design and operating model.
• Establish rigorous performance management across demand generation and growth: pipeline, attribution, CAC/LTV, expansion, and ROI.
• Develop and scale a high‑performing B2B demand engine (ABM, field marketing, enterprise GTM) targeting AI labs and large organisations.
• Lead product marketing and positioning, creating clear, differentiated narratives across a complex product and customer landscape.
• Partner closely with sales to strengthen sales enablement and land‑and‑expand motions.
• Drive cross‑functional go‑to‑market execution, including launches and expansion into new customer segments.
• Build Prolific’s brand awareness and category presence, ensuring we are top‑of‑mind for AI and research leaders.

Qualifications

• 10+ years leading and scaling marketing in high‑growth tech or scale‑up environments.
• Proven ownership of a full‑stack B2B marketing function, spanning multiple disciplines.
• Track record of building and executing strategies that drive pipeline and revenue growth.
• Experience operating in enterprise B2B environments, ideally with complex or technical products.
• Exposure to AI, developer, or data‑driven ecosystems strongly preferred.

Skills and Approach

• Deep B2B marketing expertise, particularly in demand generation, ABM, and enterprise GTM.
• Ability to translate complex products and markets into clear, differentiated positioning.
• Strong understanding of sales enablement and land‑and‑expand models.
• Commercial and analytical mindset, with a focus on pipeline, revenue, and ROI.
• Comfortable operating at both strategic and hands‑on levels in fast‑moving, ambiguous environments.
• Builder mindset, with experience creating structure and processes from first principles.
• Evolve marketing to be more AI‑forward and scalable, leveraging new tools and approaches to increase speed, insight, and impact across the team.

Leadership

• Proven ability to build, lead, and develop high‑performing, multi‑disciplinary teams.
• Experience overseeing product marketing and brand, even if not your core background.
• Strong operator who brings clarity, structure, and alignment to complex organisations.
• Comfortable acting as a builder and change agent, not just an optimiser.
