The Problem

1 in 3 students have been scammed or made to feel unsafe on a general marketplace.

The Old Way
Anonymous strangers from across town
Static photos that hide the real condition
No consequences for ghosting or scamming
Zero accountability after the transaction
The SELT Way
Verified, enrolled students only
Mandatory 15-second condition video
Student Conduct consequences for bad actors
Full accountability backed by your university
HOW IT WORKS

Three reasons students choose SELT.

INSTITUTIONAL SSO

Your university ID is your passport.

Sign in once with your .edu credentials. There is nothing new to create and nothing extra to remember. Your enrollment status is verified in real time before you can list or buy anything.

VIDEO FIRST

15-second condition video. Required.

Static photos hide damage. A live walkthrough cannot. Every listing requires a short video before publishing. What you record is what buyers get.

SELT upload flow
ACCOUNTABILITY

Fraud has real consequences.

Transaction disputes are routed directly to your institution's Student Conduct office. Your academic standing is a stake in every transaction.

No other marketplace ties transactions to academic standing.

Provisional patent filed, USPTO 2026.

Real listings. Real students.
