Senior Product Manager - Growth

Can you help us fix the world’s most broken supply chain? The fashion industry produces over 100 billion garments a year. 60% end up in landfill — not because people don’t want these clothes, but because the supply chain for getting secondhand fashion from donation to resale is completely offline, manual, and broken. Fleek is fixing this. Our mission is to make secondhand the first choice. We’re building the infrastructure powering the global secondhand clothing trade — through a B2B marketplace and the AI systems digitising the supply chain behind it. Through Fleek, vintage stores, online resellers, and retail buyers source graded secondhand inventory directly from wholesalers and rag houses across multiple countries. Our key enabler is FleekSort — an AI model fine-tuned on secondhand fashion — that can grade, price, and categorise items with just a photo, turning what has historically been an opaque and manual trade into a structured, searchable, and tradable global inventory layer. Since 2022, we’ve saved 9 million items from landfill and tripled in size year-on-year. We’ve raised ~$50M from a16z, Y Combinator, Burda Principal Investments, HV Capital, and others, and have recently closed our Series B. Our advisors and private investors include operators behind Depop, Shopify, and Postmates. Today, we serve thousands of resellers and retailers across the UK, Europe, and the US. With the secondhand fashion market projected to reach $350B by 2027, Fleek is building the AI-native operational and financial backbone for secondhand commerce globally. We’re looking for people who want to build something that matters — and move fast doing it. Sound good? Keep reading. Why This Role Stands Out As a Senior PM in our Growth team you'll own a seller platform, where your users range from professional resellers making high-volume purchasing decisions to first-time vintage buyers, and where AI is embedded into the core product experience through FleekSort. You'll operate across the full product loop: problem discovery, solution design, ship, and learn. You'll talk to users directly, self-serve your own data, prototype solutions before pulling in full resources, and ship experiments where you can see the impact in the numbers the same week. The platform handles 500,000+ items a month today and is scaling to over a million by end of year. You'll shape how we build product as AI changes the landscape — and you'll do it with a team that treats product as a leadership discipline, not a process role. What Makes You a Fleek Senior PM? Full-Loop Operator: You own the entire product cycle — from problem understanding through solution design, launch, learn, and iterate. You don't hand off; you follow through. Ambiguity-Native: You thrive when the problem isn't fully defined. You take initiative, frame the question, and drive toward clarity without waiting for a spec. Data-Driven, Not Data-Buried: You use data to make decisions, not just to report. You self-serve insights, triangulate quant, qual, and market signals, and let evidence shape direction. AI-Curious: You're proactive about learning and applying AI in your work. You use AI to close skill gaps across data, design, engineering, and GTM — and you evaluate AI outputs critically. User-Obsessed: You talk to users regularly. You have high EQ, translate messy user problems into clear product direction, and keep the customer at the centre of every decision. Design-Fluent: You have strong product taste. You can turn problems into solutions, express ideas visually, and prototype before pulling in full resources. What You'll Do Own a product domain end-to-end: strategic thinking, problem identification, solution design, ship (prototype, MVP, small audience A/B), learn, iterate. Work embedded in a collaborative, cross-functional pod with engineering and design. Talk to users regularly and translate insight into product direction. Use data (including AI-assisted tools) to self-serve insights and validate decisions. Prototype and visualise solutions to move fast before pulling in full design or engineering resources. Navigate shifting priorities with pragmatism. Fill gaps. Product here is a leadership discipline: you do what the product needs to succeed. What You Bring 7+ years of product management experience in B2C businesses with experience building product that people love and has grown through your work. Strong product taste and design fluency. You have opinions on UX, can turn problems into solutions, and express ideas visually. Data literacy. You self-serve insights, set up and interpret experiments, and triangulate from multiple signals to inform decisions. AI fluency. You're proactive about applying AI in product development. You're comfortable using AI to close skill gaps and can evaluate AI outputs critically. Cross-functional leadership. You bring partners along, communicate a clear path forward, and connect work to company goals. Startup or scale-up experience. You've worked in fast-moving environments with high ownership and evolving requirements. Comfort with ambiguity. You don't need a detailed spec to start moving. You take a problem statement and drive toward a working solution. Nice to Have Experience with marketplace, supply chain, or fashion/retail products. Familiarity with AI/ML product development and working alongside AI-powered features. Experience with growth product management: experimentation platforms, funnel optimisation, activation loops. Background working with international teams across multiple time zones. How We Work Fleek is an in-office company. We believe the best work happens when people are together — the quick decisions, the cross-functional energy, the ability to solve problems in real time. Most of the team works from our London HQ 3–4 days a week. We’re not prescriptive about it. Performance and trust matter more than attendance. For your first six months, we’ll ask you to prioritise being in the office — to learn the business, build relationships, and get up to speed. After that, you’ll have genuine flexibility to manage your own time. We hire adults and treat them accordingly. The Practicalities Location: London HQ — Heneage Street, E1 (Shoreditch / Aldgate East) Work model: In-office, typically 3–4 days per week. Full-time in the office for your first six months, then genuine flexibility earned through trust and performance. Level: Senior Stage: Post-Series B, hyper-growth Team: 100+ across London, India, and Pakistan Culture: High ownership, non-hierarchical, fast-moving. Founder-led with strong opinions loosely held. Our Values Five values shape how we work at Fleek: Dream Big and Disrupt Yourself: Push the most ambitious version of what you’re building. Step out of your comfort zone. Nothing is out of reach. Absolute Ownership: The buck stops with you. Drive initiatives to completion. Experiment, learn, persevere. The job isn’t done until the job is done. Curiosity Leads the Way: Don’t accept anything at face value. Ask questions you don’t know the answer to. That’s how you innovate. Talk to the Customer: Deeply understand their challenges, motivations, and ambitions. Every decision starts with the customer at the centre. Embrace Diversity: A global team building for a global supply chain. Bring your authentic self and embrace the diversity of everyone you encounter.
