Daebae

Daebae kills the zombie listing problem. Every post hard-expires in 24 hours — if it's live, it's available. No ghosts, no stale feed, no negotiating with someone who sold it last week.
Daangn's user base is now 63.8% aged 30s–50s. The MZ generation has left. Daebae is built for the vacancy — starting in Yeoksam, where 68% of residents are single-household officetel dwellers with no storage and high urgency.
Three pillars: P2P resale within 500m, B2C surplus flash sales for cafes and bakeries, last-minute slot booking for gyms and studios. Commission-free. Subscription model.
Currently in private beta, Yeoksam-dong, Gangnam.
