Professional second-hand sellers make that happen, and with ruit they sell on Wallapop, Vinted, eBay and more from one place. Everything they list, sync or sell runs through our backend, and their catalogues keep growing. We're hiring one backend engineer to get ruit ready for 100 times today's load: PostgreSQL and Redis on their own servers, PgBouncer, more web and Celery workers, and monitoring where every alert points at its cause.
In a year, ruit handles a million listings on infrastructure you designed, and every alert says what broke before anyone asks.
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.
