🏢 About Prolong

Prolong is entering an exciting phase: we’re transitioning from startup to scale-up. We’re experiencing strong traction and are closing in on our Product-Market Fit.

Prolong is a white-label SaaS platform that empowers fashion brands to turn after-sales services—such as repairs, alterations, recycling, refurbishing, and spare parts management—into powerful drivers of sustainable growth and new revenue. By reshaping how brands manage product repairability, lifecycle, and circularity, Prolong unlocks new models for sustainability, operational efficiency, customer loyalty, new revenue streams and global scale.

We are already trusted by leading brands such as Fusalp, Veja, The North Face, Bocage, validating both the strength of our mission and the scale of the opportunity.

We are guided by strong values:

🫶 CARE — We care for each other, our work, and every single user.

🚀 AMBITIOUS — We challenge the status quo and build globally by default.

🤝 TRUST — We own our results and lead through reliability and excellence.

🧑‍🎓 FAST LEARNERS — We move fast, learn faster, and never stop improving.
