PARTNER DEVELOPMENT MANAGER, PROLIFIC FOR RESEARCH Location: San Francisco (Hybrid) Prolific Prolific is the world’s most trusted infrastructure for human data. Today, tens of thousands of researchers from enterprises and top universities across the globe rely on Prolific to power their work, from peer-reviewed studies to the next generation of technological breakthroughs. Prolific's partnership ecosystem is a key growth engine for Prolific. The next generation of AI-powered research platforms are growing rapidly disrupting the market, and the foundation of their success is the authentic, rich human data that only Prolific can provide. To help us drive this next phase of growth, we are looking for a commercially driven partnerships professional with 5-7+ years of experience building and growing revenue-generating partnerships within research or industry. Success will be measured against the team revenue target, so close collaboration with Partner Success and Partner Sales Managers based in the UK will be critical. We want the successful candidate to help shape our partner strategy and direction and lead commercial conversations with our largest strategic partner opportunities, so knowledge and demonstrable experience of working with platform partners in the market research, UX/product testing, or user research space is a huge plus. This will be our first US partner hire, and the role will report directly to the Head of Sales and Partnerships at Prolific for Research. We'd ideally like someone based in the Bay Area, given the concentration of partners and prospects there, though we'll consider candidates elsewhere in the US who can travel to San Francisco frequently. The Role The market research industry is being disrupted by rapidly growing AI native research platforms. At Prolific, we have invested in a strong channel partner ecosystem across AI-moderated research, UX/product testing, and user research that now sees us embedded as the participant infrastructure for the most rapidly growing companies in this space—Outset, Maze, ListenLabs, and Dialogue AI, to name just a few. As our first on-the-ground partner team hire in North America, the Strategic Partner Lead will work closely with partner success and partner sales to own founder and executive-level relationships with high-value research partners, build Prolific’s profile across the startup and scale-up ecosystem, and drive meaningful revenue growth across both existing and new partnerships. The partner lead will report to the Head of Sales and Partnerships at Prolific for Research and be based in the Bay area. This is a high-visibility, commercially focused role that sits at the intersection of partnership growth and new partner development. You will be the partnership face of Prolific for Research in the US, engaging at founder and executive level, maximizing our share of spend across existing partners, and identifying and working with partner sales to close the next generation of research platform partners. Success in the role is measured by performance against the global team revenue target, covering both existing and new logo partners. This is a fabulous opportunity to make a huge impact within a well-funded and very well-respected scale-up, driving growth in a key focus market for Prolific. We want you to have a voice, help shape our partnership strategy, and directly contribute to the success of the sales and partnerships team. What you'll be doing Drive Revenue Growth Across the Partner Ecosystem * Own and deliver the partner team revenue target, covering growth across existing partners and new partner acquisition. * In collaboration with partner success and partner sales, increase revenue and usage across the existing partner base by identifying expansion opportunities, deepening platform adoption, and maximizing Prolific’s share of spend. * Build senior relationships with US target partners and optimize time to revenue once engagements are closed. * Support complex, non-standard deal negotiations with strategic partners. Build and Own Senior Partner Relationships * Lead executive and founder-level engagement across Prolific’s research partner ecosystem—including heads of research, C-suite stakeholders, and founding teams/investors. * Work closely with your partner success colleague to build deep, trusted relationships with our largest partners in North America as well as with emerging platform providers across the research and AI-moderated research spaces. * Serve as the senior commercial point of contact for US-based partners, ensuring Prolific is embedded at the strategic level within key partner accounts. Act as a Strategic Partner to Key Accounts * Develop a deep understanding of partner research workflows, business models, and growth objectives. * Identify growth opportunities within accounts and shape how partners leverage Prolific’s platform—including participant supply—to maximize value and drive usage. * Provide strategic input that influences partner direction and strengthens long-term commercial relationships. Build Market Presence and Ecosystem Awareness * Represent PfR externally at conferences, industry events, and speaking engagements relevant to US research, AI tools, and the SaaS ecosystem. * Build Prolific’s brand and credibility with founders, operators, and investors across the US startup and scale-up community. * Identify and develop new channels, communities, and networks that expand Prolific’s reach and pipeline. Collaborate Closely Across the Business * Work closely with Partner Success and Partner Sales colleagues to ensure a coordinated approach across the full partner lifecycle—from pipeline and onboarding through to expansion. * Feed market intelligence, partner insights, and competitive dynamics back into product, marketing, and strategy teams. * Act as a bridge between the US market and the broader Prolific partnership team, ensuring local context shapes global decisions. What you'll bring * 5-7+ years of experience with a demonstrable track record in a quota-carrying partner, sales, or business development role—ideally within the market research, UX/user research, product testing, or adjacent SaaS space. * An established network within the US research, AI tools, or SaaS ecosystem, with a proven ability to build relationships at the founder and C-suite levels. * Proven track record of meeting or exceeding revenue targets in a commercially focused partnership or sales capacity. * Experience working with usage-based commercial models and land-and-expand growth motions. * Exceptional communication and interpersonal skills—as comfortable in a one-to-one exec conversation as presenting on a conference stage. * A collaborative, low-ego working style: you build trust quickly with partners and colleagues and know how to add value across a team. * Comfortable operating in a scale-up environment—resourceful, experimental, and energized by ambiguity. * Willing and able to travel regularly across North America for partner meetings, conferences, and industry events. * Knowledge of the participant/panel/recruitment market within research What we expect from you We’re proud of the culture we’ve built at Prolific, and as a Prolifico, we expect you to contribute positively to our workplace culture by embracing our core principles: * Celebrate our wins—for our customers, partners, prolificos, and Prolific. * Break down silos to partner across teams, fostering a unified effort toward company objectives. * Strive for excellence in all that you do, setting and working towards ambitious goals. * Continuously seek opportunities for improvement and innovation, pushing the boundaries of what’s possible. * Act with integrity, prioritizing customer satisfaction and trust above all else. * Actively seek and act on customer feedback to deliver solutions that exceed their expectations. * Manage your time efficiently, focusing on tasks that drive impact and support our mission. * Take ownership of your responsibilities, and be accountable for your progress and the quality of your work. * Approach challenges with a growth mindset, viewing them as opportunities for learning and innovation. * Encourage and participate in experimentation, embracing failure as a valuable learning experience.

ABOUT US Humaans is building the next generation of infrastructure for the workplace; software designed for companies that are scaling fast, operating globally, and pushing into new boundaries. What started as a system of record has evolved into a broader platform for operating people globally. With Athena, our agentic AI layer, Humaans moves beyond data management into intelligent orchestration, connecting workflows across HR, IT, Finance, and Operations so organisations can act faster and with greater confidence, redefining how work gets done.

These teams don’t buy software for features,they buy leverage. The ability to run faster, cleaner, and with more control as complexity compounds.
