Thribble - A marketpalce for Students

Thribble – The Student Marketplace

Inspiration

College students constantly struggle to buy and sell essentials like lab coats, textbooks, and dorm furniture, often needed for just a semester. Current alternatives (Facebook groups, Craigslist, Snap stories) are messy, unsafe, and not tailored to students. Thribble was created to fix this: a trusted, student-only marketplace built for campus communities.

What it does

Thribble is a web and mobile app where students can list, browse, buy, and sell items securely.

Core Features

Campus verification with .edu email for trust & safety.
Smart categorization and AI-powered fair price suggestions.
Fast listing creation with photos, title, description, and price.
Swap / trade option for cash-free exchanges.
Search & filters (keyword, category, price, date, sort by newest / price, etc.).
Messaging system for direct, secure communication between buyers and sellers.
Recommendation System that adapts listings based on:
- Location: prioritize items within the seller’s dorm or nearby housing.
- Category relevance: recommend textbooks and lab gear to students in relevant programs.
- Behavioral signals: personalize feeds using browsing, search, and purchase history.
- Temporal boosts: surface time-sensitive items (e.g., semester-end furniture, event tickets).
- Trust signals: verified and highly rated sellers receive higher placement.
Points & Rewards: earn points for selling/buying that can be redeemed for discounts or gift cards.
Basic trust & safety: report listings/users, moderation tools, and ASU verification badge.
