Role

The Strategic Partnerships team builds deep, long-term relationships with Whatnot sellers - guiding them to scale efficiently, elevate buyer experience, and innovate on the platform.

This role sits at the intersection of partnership management, category strategy, and go-to-market execution. You’ll partner closely with your Category Lead, Marketing, Trust & Safety, and Product teams to turn seller insights into action and ensure your team delivers exceptional results for sellers and buyers.

You’ll own a book of up to 200 sellers, applying a structured, data-informed approach to coaching, engagement, and performance improvement. By combining automation, AI-powered insights, and a deep understanding of seller behaviour, you’ll help sellers reach key growth milestones and scale their business successfully on Whatnot.

This role requires sharp and ruthless prioritisation, strong operational judgment, and the ability to translate data into actionable outreach at scale. You’ll act as both strategist and operator - ensuring every seller receives the right level of guidance at the right time, while balancing efficiency and impact across your portfolio.

• Manage a scaled book of business. Own relationships with high-potential sellers, balancing proactive outreach with data-driven prioritisation
• Drive growth and account health at scale. Use AI tools and analytics (Salesforce, ChatGPT, Gong) to identify performance trends, automate communication, and execute structured coaching programs that improve seller performance
• Prioritise ruthlessly. Focus time and energy on sellers with the highest engagement potential and growth opportunity, applying a clear prioritisation framework to drive results efficiently
• Deliver structured communication. Execute scaled outreach campaigns, monthly education seminars, and automated growth treatments that improve seller account health and business fundamentals
• Leverage AI for insights and efficiency. Utilise Whatnot’s AI-enabled toolset to summarise seller performance, generate outreach content, and automate repetitive tasks, freeing capacity for strategic engagement
• Collaborate cross-functionally. Partner with Category Leads, Marketing, and Product to surface seller trends, share feedback, and align scaled interventions with category priorities
• Track, measure, and report. Maintain high data hygiene in Salesforce, logging outreach, treatments, and seller milestones to inform team-level metrics and continuous improvement
• Build scalable best practices. Share insights, pilot learnings, and scaled comms templates to strengthen team-wide effectiveness and inform future Development playbooks

We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection. Team members in this role must live within commuting distance of our London, UK hub.
