Maker of CardHunt, Pokémon grading data

About

I'm Stefan, an independent maker from the Netherlands. I build CardHunt (cardhunt.io), a free tool that combines PSA population data with sold prices to show which Pokémon cards are actually worth grading, and which ones are traps. I'm here to share what I'm learning, give honest feedback on other makers' launches, and get feedback on my own work. Always happy to talk about data products, small-team shipping and the trading card hobby.

CardHunt - Find which Pokémon cards are actually worth grading

CardHunt combines the PSA population report with prices to show which Pokémon cards pay off after grading, and which are traps (a +2,000% PSA 10 price can still lose money when few copies get a 10). It computes expected value after grading, shipping and selling fees, tracks eBay listings of the best candidates with a centering check, and shows which cards trade near their own 6-month low. Browsing is free; the optional Hunter plan adds alerts and the real total cost.
