Every business in Winnipeg produces byproducts. Spent coffee grounds. Used cooking oil. Sawdust. Fabric offcuts. Most of it gets hauled away at a cost — while across the city, makers, gardeners, and small producers are paying to source the exact same materials.
Upstreams intercepts materials before they become waste.We're a directory-first marketplace that makes an invisible connection visible: businesses that have useful byproducts, and people who can put them to work.
Waste suppliers are already paying for disposal — this platform reduces that cost and gives them an ESG story. Waste recipients are cost-sensitive — free or cheap raw materials are highly attractive.
Phase 1 is Winnipeg. The goal is to prove match rate, build the local network, and create a blueprint that can be replicated city by city across Canada.
