Fleek raises £19M Series B to build AI for secondhand fashion's supply chain
July 8, 2026
Fleek, the London-based startup building the technology behind the global secondhand clothing trade, has raised £19 million ($25 million) in a Series B round led by Burda Principal Investments, an early backer of Vinted.
The secondhand apparel business is vast but stubbornly analogue. Up to 24 billion garments a year move from donation bins in cities such as London, Paris and New York to sorting and grading centres scattered across the world, yet this $200 billion-plus industry still runs on manual assessment, inconsistent grading standards and disconnected trading networks with little pricing transparency.
Fleek's answer is a B2B marketplace paired with its own AI. At its centre sits Fleek Sort, a custom vision-language model trained on millions of the company's own transactions over four years, which identifies, categorises, grades and prices used clothing from a photo or short video. Once processed, inventory is listed automatically on Fleek's marketplace, where its pricing, search and matching systems connect stock with buyers. Graders in sorting hubs across Pakistan, India and Dubai already use the model, with pilots running in the UK, Europe and the US. Fleek was founded in 2021 by Abhi Arora and Sanket Agarwal.
The platform now links more than 2,000 verified wholesale suppliers and graders with over 50,000 retailers, resellers and boutiques across more than 100 countries. Fleek says it has kept more than 12 million items in circulation, and the round takes its total funding to roughly $45 million, up from about $20 million raised previously.
Burda led the round having backed Vinted in its early days, a record its Europe managing director Julian von Eckartsberg pointed to in casting Fleek as infrastructure the next generation of fashion will depend on. New investors eBay, FJ Labs and H14 joined, alongside returning backers Andreessen Horowitz, HV Capital and Y Combinator. The capital will go toward developing Fleek Sort, expanding the engineering team and growing the supplier and buyer network.
