Key points

  • Loam Bio secured $73M to scale its microbial seed coating technology, which helps farms capture and store atmospheric carbon in the soil.
  • The technology works by using specialized fungi that produce stable, melanin-rich biomass, turning agricultural land into a verifiable carbon sink.
  • This creates a new revenue stream for farmers, who can sell the quantified carbon removal as credits to corporations with ESG and net-zero goals.
  • The investment highlights a major trend in AgTech: creating economically compelling products that align farm profitability with positive environmental outcomes, like improved soil health and climate change mitigation.
  • For the broader food industry, this technology offers a pathway to more resilient and sustainable supply chains, with the potential for "carbon-farmed" product differentiation.
