The voluntary carbon market spent a decade selling promises instead of proof — and conservation finance is determined not to repeat the mistake. A new startup called Landseed, backed by the nonprofit that owns Patagonia, launched this month with $500,000 in funding and a specific thesis: the nature-based market needs an independent measurement standard before it can function as a credible asset class, and Patagonia conservation investors now have a company trying to build one.
Landseed, a public benefit corporation based in Ventura, California, announced June 12 that it had secured a $400,000 social-impact investment from the Richard King Mellon Foundation — one of the 50 largest foundations in the world — bringing its total funding to $500,000. The money will go toward building what the company calls “the measurement layer for nature-based markets”: a three-part system combining AI-enabled sensor hardware, a new ecological commodity called Earth Credits, and a structured data feed called Earth Signals.
The company was co-founded by Greg Curtis, executive director of Holdfast Collective — the nonprofit that owns 98% of outdoor brand Patagonia — alongside Alex Roessner, an environmental economics graduate of Northwestern University, and Eric Dinerstein, who spent 25 years as chief scientist at the World Wildlife Fund and developed the optical sensing technology that powers Landseed’s monitoring hardware.
Selling Testimony vs. Measuring Truth
“The carbon market was built to trade testimony about carbon, not carbon,” Roessner said in the company’s funding announcement. “Every market in valuable things has an independent assay office. Gold has had one since 1300. Ecological markets have never had one. That’s what we’re building.”…
