Fleek is building the AI-native infrastructure powering the global secondhand clothing trade. The company operates a B2B marketplace and AI systems (FleekSort) that digitize the supply chain, enabling vintage stores, online resellers, and retail buyers to source graded secondhand inventory from wholesalers across multiple countries. Since 2022, Fleek has saved 9 million items from landfill and is backed by a16z, Y Combinator, and HV Capital.
As Account Manager, you will 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 scalable, high-quality account management systems and processes.
Key responsibilities include:
- Manage a customer portfolio starting in the £5-15k monthly spend range, driving 10-20% month-on-month growth in retention and wallet share
- Ensure customers spend on categories that make sense for suppliers, minimizing refunds and cancellations
- Drive customer engagement through WhatsApp, email, calls, stock lists, bundles, and personalized supplier recommendations
- Proactively identify and re-engage inactive accounts, understanding why they left and building reasons for return
- Champion self-service adoption while remaining the primary point of contact
- Build AI-enabled account management workflows that scale your ability to manage more accounts at higher quality
- Work cross-functionally with product, operations, and supply to surface customer pain points and drive platform improvements
You'll be competing for wallet share against wholesalers from the Middle East, US, and Europe. Success requires deeply understanding customer businesses, proactively solving problems, and finding creative ways to grow their spend month over month.
