# Loam Bio

> Loam Bio is an Australian agricultural biotechnology company using naturally occurring microbial fungi to help crops store more stable, long-lasting carbon in soil. Founded in 2019 by a group of farmers and climate scientists, it coats seeds with its CarbonBuilder inoculum so plants pull atmospheric CO2 into recalcitrant, mineral-bound soil carbon, and pairs the biology with its SecondCrop program that helps growers measure, verify and sell soil carbon credits. Backed by more than US$119M from investors including Lowercarbon Capital, Wollemi Capital and Marc Benioff's Time Ventures, Loam is scaling from its Orange, NSW base into the United States.
