Nori's Carbon Marketplace Bet Anchored a Tonne of Soil and a $17 Million Runway

The Seattle startup, which closed operations in 2024, raised from M13 and Toyota Ventures to pay farmers for soil sequestration before the voluntary carbon market stalled.

About Nori

Published

The math for soil sequestration is, in theory, beautifully simple. A farmer adopts a regenerative practice, like cover cropping or no-till, and the soil beneath their feet begins to bank carbon. Measure the change, verify it, and sell that tonne of CO2 to a corporation looking for a durable offset. For seven years, Nori tried to make that math work for everyone. The Seattle-based startup built a marketplace to connect those farmers with those buyers, issuing a credit it called the Regenerative Tonne for carbon stored in soil for at least a decade [Wikipedia, Unknown]. It was a clear wedge into the sprawling, messy world of carbon removal: start with the land.

The bet on agricultural carbon

Nori’s core product was a financial instrument for a new kind of commodity. A farmer would get paid for verified carbon sequestration, and a buyer,a company aiming for net-zero claims,would purchase a Nori Regenerative Tonne credit. The company’s bet was that by creating a direct, transparent market, it could unlock supply (farmers willing to change practices) and demand (corporations needing high-quality removal credits) simultaneously. In late 2023, it launched a hybrid product, the Net Zero Tonne, which paired soil sequestration with more permanent removal methods like direct air capture, a move to address concerns about the durability of nature-based solutions [Carbon Herald, December 2023]. The underlying technology stack included blockchain, aimed at providing an immutable ledger for credit ownership and retirement [TechCrunch, 2020].

Funding and the road to 2024

Investors backed the thesis with over $17 million. The funding runway was built across several rounds, with notable leads like M13 and Toyota Ventures stepping in for a $7 million Series A in early 2022 [Wikipedia, Feb 2022]. Toyota Ventures returned to lead another $6.25 million venture round in mid-2023 [Crunchbase, Jun 2023]. The table below outlines the disclosed fundraising history.

Where the wheels came off

Despite the capital, the market fundamentals proved tougher than the soil science. In 2023, Nori laid off 10 employees, about 37% of its team at the time, with CEO Paul Gambill citing broader market concerns [GeekWire, 2023]. Leadership shifted, with Gambill moving from CEO to chief product officer and later leaving the company in March 2024 while remaining on the board [GeekWire, 2024]. By 2024, operations ceased entirely. The shutdown was attributed to a stagnant voluntary carbon market and a difficult funding environment, as explained by then-CEO Matt Trudeau [Carbon Herald, 2024]. The closure highlights several intrinsic risks in the carbon removal marketplace model:

  • Buyer demand volatility. Corporate appetite for voluntary credits, especially newer soil-based credits, can freeze rapidly amid economic uncertainty or scrutiny over credit quality.
  • Measurement complexity. Verifying additionality and ensuring a tonne of soil carbon is truly new, additional, and durable for a decade requires rigorous (and costly) science.
  • Farmer economics. The payment per tonne must meaningfully offset a farmer’s risk and effort in changing practices, a unit economics challenge at early market prices.

Nori’s story is a case study in climate tech unit economics. The back-of-the-envelope calculation is stark: with roughly $17 million in funding, the company needed to facilitate the sale of hundreds of thousands of tonnes just to cover its own operational burn, before proving the model could scale to the gigatonne level needed for climate impact. It was a capital-intensive race to prove a market could be created before the runway ended. In the end, Nori’s bet was on a future that required it to beat not just other marketplaces like Indigo Ag or Boomitra, but the entrenched skepticism of the entire voluntary carbon market itself.
