Hey Product Hunt! I'm Frank, founder of Cardtag. I built this because I kept losing every connection I made at tech events across Africa. Great conversations, exchanged numbers, then... nothing. No follow-up. No relationship. I realized it wasn't a discipline problem — it was a systems problem. So I built the system. Cardtag gives every event a live networking Arena. Attendees join with a code (no app download), see who's there, connect instantly, and get AI-powered follow-up suggestions after the event so no connection gets lost. We just ran our first pilots and the results blew us away — attendees were connecting before the doors even opened. Built for event organizers, community builders, and coworking spaces across Africa. Free to start. Would love your feedback — what would make you use this at your next event?
