Senior Growth Analyst

Senior Growth Analyst 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. ABOUT THE ROLE This is a Senior Growth Analyst role sitting at the intersection of marketing, data, and commercial strategy. You'll own the analytical backbone behind Fleek's growth engine, spanning influencer, affiliate, organic, paid, and lifecycle, and your work will directly influence how we allocate spend, prioritise channels, and scale acquisition. You'll report into our growth leadership and work closely with marketing, product, and engineering in London. This isn't a reporting role. You'll be the person who turns messy marketplace data into clear decisions that change how the business grows. WHY THIS ROLE STANDS OUT Fleek is a marketplace where every item is unique, inventory is graded by AI, and the buyer journey doesn't follow any standard ecommerce playbook. Traditional attribution models break down here. You'll need to build new ones. You'll own attribution modelling across every acquisition channel, from influencer and affiliate partnerships to paid social, paid search, and organic. You'll design incrementality tests, build cohort analyses, and calculate the true ROI of campaigns that span creators, affiliates, and performance marketing. Your insights will directly determine where we invest and where we cut. This is a marketplace scaling from thousands to tens of thousands of active buyers. The data infrastructure is being built in real time. If you get energy from messy data, finding the signal, and helping teams spend way smarter, this is the role. WHAT MAKES YOU A FLEEK GROWTH ANALYST? - Signal Finder: You see patterns in noisy data that others miss. You don't just report numbers, you find the insight that changes the decision. - Attribution Obsessed: You think deeply about how to measure what actually works. MMM, MTA, incrementality, positional models, you know when each applies and where each breaks. - Commercially Wired: You connect analytical outputs to business outcomes. You think in CAC, LTV, payback periods, and ROAS, not just clicks and impressions. - Comfortable with Ambiguity: Fleek's growth data is complex and evolving. You thrive when the data is messy, the tracking isn't perfect, and you need to find the answer anyway. - Action-Oriented Communicator: You translate complexity into "here's what to do." Yo ...
