Fleek

Founded in London in 2021, Fleek addresses the fragmented, largely offline supply chain that sits behind every piece of secondhand clothing bought and sold globally. Up to 24 billion secondhand clothing items move through global supply chains each year, still sorted, graded, and traded largely by hand. Fleek’s B2B marketplace connects 2,000+ wholesale suppliers with 50,000+ retailers and resellers across 100+ countries, bringing transparency and efficiency to a market that has historically operated through disconnected networks with little pricing consistency. At the core of the platform is Fleek Sort, a proprietary AI model trained on millions of real-world secondhand transactions, enabling suppliers to identify, grade, and list inventory at scale. Every transaction feeds back into the model, creating a proprietary intelligence layer that improves continuously with scale.
