BarterZ: marketplace MVP

Barter anything, starting with Pokémon, on a community-driven trading platform.

About this reel

BarterZ is a trading card marketplace for desktop and mobile where collectors list cards, get recommendations and trade cards plus cash through offers and counter-offers, with Stripe payments and live updates. Built by INTERS3CT with React, Vite, Supabase and Stripe.

The Challenge

Founder wanted to validate a barter marketplace where users trade goods and services without cash, starting with a niche community of Pokémon collectors before expanding.

Our Solution

Built the BarterZ MVP with item listings, search, in-app chat, and trade coordination, launched fast with a niche-first GTM to validate the concept before scaling categories.
