About project

From Flea Market Chaos to Smart Campus Commerce.

Rumie set out to redefine how students buy, sell, and connect within their university ecosystem. The idea? A trusted, university-branded marketplace students actually want to use.

The challenge was creating a robust, scalable system that felt like a lifestyle app but worked like an enterprise backend. With seamless integrations, financial compliance, and real-time features baked in — Rumie is now the plug for campus classifieds and student-led commerce.

Working with Addictive Media was a
total game-changer.

Their team didn’t just "build an app" — they helped define the entire product experience. From deep backend integrations to designing an interface our students love using, they nailed it. The admin dashboard alone has made campus onboarding effortless, and the system scales like magic. We're already seeing organic adoption grow semester after semester.

Application Design

Built for Campus. Loved by Students.

With a cross-platform app engineered to work at lightning speed, Rumie offers a marketplace that works everywhere students do. Whether they’re listing a used textbook or grabbing last-minute event gear — it’s all done in a few taps.

 

Push notifications, secure chat, payments, listings, and analytics? All under one roof.
Cross-platform. Cross-campus. No compromise.
