Fleek raises $25M to build AI infrastructure for secondhand fashion

Secondhand fashion is growing, but the supply chain behind it remains fragmented and heavily manual.

What happened

Fleek raised a $25M Series B led by Burda Principal Investments, with participation from eBay, FJ Labs, H14 and existing investors including Andreessen Horowitz, HV Capital and Y Combinator.

The company operates a B2B marketplace connecting secondhand clothing suppliers with retailers and resellers. It has also built AI systems for sorting, grading, pricing, merchandising and matching inventory.

Fleek says its network includes more than 2,000 suppliers and graders, over 50,000 retailers and resellers, and users across more than 100 countries.

Why it matters

This is stronger than another resale marketplace.

The difficult infrastructure problem in secondhand fashion is that inventory is heterogeneous, fragmented and often processed manually. Better sorting, grading and pricing can improve both recovery economics and marketplace liquidity.

Fleek is using marketplace data and AI to digitise that operating layer rather than focusing only on consumer resale.

The bigger picture

Circular commerce increasingly needs industrial and software infrastructure behind the storefront.

The next wave of resale companies may win by organising supply, standardising quality and making fragmented inventory easier to trade at scale. Fleek’s funding reflects that shift.
