Material Reuse
at Scale.
Material Index tackles construction's biggest blind spot: waste. We built a system to audit, exchange, and reuse building materials across the supply chain.



The Material Index
Engine
The construction industry generates more waste than any other sector, and most reusable material ends up in landfill because there's no system to track or trade it.
Fragmented Systems &
Cognitive Overload
Demolition firms had no buyers; new builds had no visibility into existing material stock — leaving 70% of viable inventory wasted.
“Every site has tons of perfectly good material. We just needed a way to make it visible.”
