About
Zelbi helps families facing rising costs get things they need, free, from people nearby. Snap one photo of something you no longer use, Zelbi writes the listing, and someone close by claims it. Items are always free and givers pay nothing. Your exact address stays private: the map shows only an approximate area, and only the claimer sees the exact spot. Chat stays in the app with no phone numbers or emails shared, and every claim is tied to a real account. Live across Seattle and nearby cities.
Attention & discussion velocity
Not enough snapshots yet. Run the snapshot worker every 15 min to build the time-series.
Performance
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
