Manager, Account Executive in London

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. 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. Our advisors and private investors include operators behind Depop, Shopify, and Postmates. 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 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 need to deeply understand your customers' businesses, proactively solve their problems, and find creative ways to grow their spend on Fleek month over month. 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.
