Account Manager

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: 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 while tripling in size year-on-year. We're backed by some of the world's best investors, including a16z, Y Combinator, and HV Capital, alongside world-class angels who helped build 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. About the Role We're looking for an Account Manager to own and grow a portfolio of Fleek's marketplace customers, driving retention, wallet share expansion, and long-term customer health. You'll manage a book of resellers, vintage stores, and enterprise buyers across the UK and US, acting as their single point of contact while building the systems and processes that enable scalable, high-quality account management. Your customers range from online resellers and brick-and-mortar vintage shops to large-scale enterprises moving significant volume through Fleek. This isn't a passive relationship management role. You'll be competing for wallet share against wholesalers from the Middle East, US, and Europe. You'll need to deeply understand your customers' businesses, proactively solve their problems, and find creative ways to grow their spend on Fleek month over month. The ideal candidate brings entrepreneurial energy, comfort with ambiguity, and an AI-first approach to scaling themselves and their portfolio. What You'll Do • Own Your Portfolio: Manage a book of customers starting in the £5-15k monthly spend range, with a clear path to owning higher-value accounts as you ramp. Drive 10-20% month-on-month growth in retention and wallet share. • Build Healthy Customers: Ensure customers are spending on categories that make sense for our suppliers, with minimal refunds and cancellations. A healthy customer is a retained customer. • Drive Customer Engagement: Use WhatsApp, email, calls, stock lists, bundles, and handpicked supplier recommendations to keep customers active, ordering, and expanding their spend. • Win Back Lapsed Customers: Proactively identify and re-engage inactive accounts. Understand why they left and build compelling reasons for them to return. • Champion Self-Service: Act as the primary point of contact while actively encouraging and enabling customers to use the Fleek platform independently. Your goal is leverage, not dependency. • Build AI-Enabled Account Management: Work alongside the team to build AI-powered workflows that scale your ability to manage more accounts at higher quality.
