We want second-hand to become the first way everyone in Europe shops. Millions of products sold again instead of made new, millions of euros for the people who sell them, and a world a bit better than we found it.

Professional second-hand sellers make that happen, and with ruit they sell on Wallapop, Vinted, eBay and more from one place. Every marketplace you connect opens a new market to all of them at once. Next up: Facebook Marketplace, Etsy, Poshmark, Mercari, Whatnot, Grailed, Depop, Vestiaire Collective, Amazon, TikTok Shop and more. We're hiring two engineers to build them, by API or by reverse engineering, and to catch each breakage before a seller does.

We've raised close to €1M from Angels Capital, Decelera Ventures, Abac Capital and Successful Fund, among others, and we're going for €1M in ARR by the end of 2027.

What we're looking for
- Python in production, ideally Django.
- Integrations you kept alive after the other side changed.
- You can rebuild an API from an app's network traffic.
- You code with AI agents every day.
- Working English. The team works in English.




- You can already work legally in Spain. We don't sponsor visas.
