A mobile-first marketplace that enables verified students to buy, sell, rent, communicate, and discover opportunities within their own university communities — every interaction begins with trust.
Students buy and sell thousands of products every semester — furniture, textbooks, electronics, sports tickets, clothing, dorm essentials. Unfortunately, existing marketplaces created several challenges: meeting unknown buyers, no university verification, scattered communication, fake listings, and poor campus organization.
The goal wasn't simply to build another marketplace. The goal was to create a trusted digital community designed specifically for college life.
University email verification creates trust before every interaction — every member is confirmed to be a real student.
Buy and sell within your campus community — furniture, textbooks, electronics, and dorm essentials, all local and verified.
Rent clothing, furniture, textbooks, and more directly from fellow students — affordable, sustainable, and local.
Discover university activities through integrated event calendars — never miss what's happening on campus.
Communicate directly with buyers and sellers inside the app — no need to share personal contact information.
Build trust through verified ratings and community feedback — reputation that follows you across every transaction.

Every interaction strengthens both the marketplace and the wider university community.
The gateway to the entire platform. Every student verifies their identity with a university email before they can browse, post, or message — establishing trust from the very first interaction.
The heart of the app — a vibrant, scrollable feed mixing listings, rentals, and community posts, all from the user's own campus. Energetic but organized, never overwhelming.
Every conversation happens inside the app, tied directly to a listing for full context. Verified badges build confidence, and no personal contact details ever need to be exchanged.
University activities surfaced directly inside the marketplace app — students discover events and can buy or sell tickets for the same events without leaving the platform.
Every student's reputation lives in one place — verified status, ratings, reviews, and active listings. A quick trust check before any transaction begins.
The platform was engineered to support thousands of simultaneous users, growing campus communities, secure messaging, and scalable marketplace operations.
Verified .edu student authentication ensures every member is a confirmed, real student.
A centralized campus marketplace brings every listing into one trusted, campus-specific app.
Ratings, reviews, and verified identities build reputation that follows every student across transactions.
Secure in-app messaging keeps every conversation organized and tied directly to its listing.
Events, rentals, and community posts give students reasons to open the app every day, not just when selling.
Rumie was designed as more than a marketplace. It became a digital ecosystem supporting campus commerce and student engagement. The modular architecture enables the platform to continue expanding with new universities, additional commerce features, and stronger community experiences.
Rumie establishes the foundation for a connected campus ecosystem. Rather than building another buying-and-selling app, the platform creates a trusted digital environment where students can connect, trade, and participate in campus life. Rumie has already begun evolving toward university-focused, white-label solutions that integrate directly with campus ecosystems.
