That's 176 contacts lost. If even 10% could've been valuable connections, we're talking about massive opportunity cost.I got obsessed with this problem after watching my own business card graveyard grow. Built a real-time networking platform (Yenhyia) that makes business cards irrelevant.The insight: The problem isn't paper vs digital cards. It's the entire networking workflow.Traditional flow: 1. Arrive at event blind 2. Random encounters 3. Awkward small talk 4. Exchange cards 5. Cards go in pocket/wallet/trash 6. Never follow upNew flow with Yenhyia: 1. See attendees before event (prep who to meet) 2. Match based on goals (mutual opt-in) 3. Chat starts with context (you both chose each other) 4. Meet in person (not random, intentional) 5. Digital card auto-shared in chat thread 6. Contact synced to phone, conversation history preservedThe technical interesting bits:- B
