About the role

Ex-YC Founder at Fleek in London. On-site, full-time. Posted May 5, 2026.

Reality check: Something didn't work out? We get it. We're looking for founders who still have that fire and want to join something that's still early but some things are already working.

Opportunity: 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've raised over $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.

We are expecting that you:

  • Ran a YC company (obviously)

  • Know what worked and what didn't

  • Still want to build something massive

  • Care about applying AI for good for this world

  • Can wear multiple hats

  • Understand both technical and business sides

We're hosting our first-ever hackathon in partnership with Andreessen Horowitz!

On Saturday, 11th July, we're opening the Fleek HQ doors in London for a one-day sprint to build the AI that makes circular fashion operate at scale. RSVP HERE: https://luma.com/usntwjdw
