Trading K-pop photocards on Twitter is broken — ghosted DMs, endless waiting, scams, and condition mismatches. FNDM fixes this with wishlist-based smart matching that pairs your cards with fans who actually want them — globally. AI auto-identifies member, album, and condition from one photo. Escrow protection inspects both sides before shipping. Built in Seoul for the global K-pop fandom, starting with photocards and expanding to TCG, anime, webtoon, and beyond.

Hey Product Hunt!
👋 I'm Max, founder of CultureCode.

After 10+ years in K-content, I kept seeing the same thing: amazing IP, rabid fandoms, but the actual trading of collectibles happens on Twitter DMs and group chats. Scams. Ghosting. Endless waiting. K-pop photocards alone are a multi-billion dollar secondary market — running on infrastructure that's basically a group chat.

So we built FNDM — wishlist-based matching for collectibles. Upload a photo, our AI tags it (member, album, condition), and we automatically match you with fans worldwide who want what you have. Both sides ship to us, we verify, then forward. No ghosting. No condition surprises.

We launched in Seoul on May 8th and are now opening global pre-registration. First 300 sign-ups get limited edition merch.

We're starting with K-pop photocards because that's where the pain is sharpest — but the same model extends to TCG, anime, webtoon, and e-sports. Long-term, we want to be the home for K-culture collectibles globally.

Would love your feedback — especially from K-pop fans, collectors, and anyone who's been burned by a Twitter trade. AMA below! 🎴
