For the Claremont Colleges
Keep good things moving through the 5Cs.
5C Exchange is a student-only marketplace for the Claremont Colleges. List what you no longer need, find what you do, and hand it off in person. No shipping, no strangers, less waste.

What it is
A trusted place to trade within your own community.
Marketplaces built for strangers don't fit a college campus. 5C Exchange is the opposite: every account is tied to a verified Claremont Colleges email, every listing comes from someone a short walk away, and every exchange happens face to face.
Post the desk lamp you're done with, the textbook you finished, or the mini-fridge that won't survive the next move. Browse what other students are letting go. Message in the app, agree on a spot, and hand it over. It's quicker than shipping, kinder than the dumpster, and it keeps money inside the community.
How it works
Three steps, start to handoff.
Sign in with your .edu
Accounts are limited to students at the Claremont Colleges. One verified email, one real person. That's what keeps the marketplace trustworthy.
Post or find an item
Add a photo, a price, and a few details in under a minute. Or search what's already listed, filter by category, and save what catches your eye.
Hand it off on campus
Message the other student in the app, agree on a public campus spot, complete the exchange, and rate each other afterward.
Features
Everything a campus marketplace should have, and nothing it shouldn't.
Verified .edu accounts
Only current Claremont Colleges students can join. No outside sellers, no bots, no anonymous strangers.
Real-time messaging
Talk to buyers and sellers in the app, arrange a handoff, and keep your phone number and personal contacts private.
Eco impact tracking
Each completed exchange estimates the waste and carbon you've kept out of the landfill, tallied on your profile over time.
Ratings & reputation
Buyers rate sellers after each exchange, and consistent good behavior earns badges, so trust is visible before you ever meet.
Donate, don't dump
List items for free or as donations when you'd rather they find a home than a bin, especially during move-out season.
Moderation & reporting
Report a listing or a person in two taps. A student admin team reviews flags and removes anything that breaks the rules.
Why it matters
Every exchange keeps something useful out of the landfill, and a little money in a student's pocket. That's the whole idea.
- REUSEFurniture, textbooks, and dorm gear get a second life instead of a one-way trip to the curb at move-out.
- LOCALMoney stays inside the consortium, and value circulates between students rather than leaving for big retailers.
- MEASUREDYour profile keeps a running estimate of the waste and carbon you've helped avoid, exchange by exchange.
Built for trust
Safe by design, not by accident.
A campus marketplace only works if people feel safe using it. Three things keep 5C Exchange that way.
Students only
The .edu gate means everyone you deal with is a fellow Claremont Colleges student, not an anonymous account from anywhere.
Meet on campus
We encourage handoffs in public, well-trafficked campus spaces in daylight, not a private residence with someone you don't know.
Report anything
See something off? Flag the listing or block the user. Reports go straight to the moderation team for review.
