About Cardium
Cardium is a Pokémon TCG collection tracker created by collectors for collectors.
Our mission
We want to give Pokémon TCG collectors a tool that truly understands their needs. Not another price aggregator, but a complete tracker: portfolio value, P&L, price history, graded, sealed, wishlist. Everything in one place.
Cardium was built as a rebuild from scratch with modern stack (Next.js 15, TypeScript, Neon PostgreSQL) focused on what active collectors truly need.
