Matching engine
How matches are ranked.
We score every potential match by what actually determines whether an exchange happens: proximity, material fit, volume fit and listing freshness.
35%
Proximity
A perfect match 200 miles away loses to a good match 5 miles away.
30%
Material compatibility
Matrix maps related streams — coffee grounds → AD operators, composting, mushroom farms.

Volume compatibility
50 kg/wk shouldn't match a recipient needing 10 tonnes minimum.
10%
Listing freshness
Active listings (updated within 90 days) score higher to keep the feed relevant.
