Most of us own things we no longer use, and most of us never get around to selling them. The effort is too high, the outcome too uncertain. Cirkular exists to close that gap.

Through an AI-powered app, Cirkular makes selling secondhand effortless: snap a photo, receive an instant offer, and schedule a home pickup. Behind the scenes, an intelligent reselling OS handles pricing, authenticity checks, and matching items to thousands of secondhand partners, all in seconds.

With purely organic growth and users across Europe, Cirkular has rehomed 3,000+ items through purely organic growth, generating over €100k for users, replacing 75,000 kg of CO2, and diverting 3,000 kg of waste from landfill.

The vision is bigger than an app: to make selling a cultural habit. The time and effort savings created by this solution bypass the intention-action gap, granting consumers far more power over their items. It puts sustainable living on the path of least resistance.

Importantly, the solution also feels cool and refreshing to use, and, as described by one of our users, addictive. The app is tech-forward and exciting, making the experience itself enjoyable. To increase user buy-in, our solution is invite-only and community-driven. We grow together with our users and maintain a strong open communication to create a social environment in which keeping secondhand items in circulation becomes a shared value and not a solo chore.

Recently, we were awarded as winners of Change100, representing the most groundbreaking and exciting impact startups to watch in 2026! We're excited to take this momentum forward and continue working toward meaningful change.
