Mast Reforestation, North America's leading post-wildfire reforestation company, has successfully raised $25 million in a Series B funding round to accelerate its expansion into biomass burial, a carbon removal method known as Biomass Carbon Removal & Storage (BiCRS).
The investment, co-led by Pulse Fund and Social Capital with participation from existing backers such as Seven Seven Six, will enable Mast to scale its efforts in restoring wildfire-affected forestland while pioneering a new class of durable carbon removal credits.
Advancing Carbon Sequestration with Biomass Burial
With wildfires leaving millions of dead trees across the Western United States, Mast is integrating biomass burial with its reforestation services to provide a scalable solution for carbon sequestration.
The company’s first project under this initiative, Mast Wood Preserve MT1, will launch in central Montana, where unmerchantable, fire-killed trees will be buried rather than burned—preventing the release of stored carbon into the atmosphere.
This method, protected under a 100-year easement, ensures that carbon remains locked away for at least a century, with research suggesting preservation could last up to 3,000 years.
Mast's approach also streamlines the post-wildfire recovery process by clearing hazardous burned trees and making way for new seedlings.
The Montana project alone is expected to generate up to 30,000 tonnes of carbon removal credits by 2026.
Investor Confidence in Scalable Reforestation and Carbon Removal
The Series B funding reflects strong investor confidence in Mast’s innovative reforestation model, which aligns ecological restoration with the growing demand for verified carbon removal solutions. Grant Canary, CEO of Mast Reforestation, highlighted the significance of this funding:
"By burying wildfire-destroyed trees, we’re not just sequestering carbon—we’re also accelerating reforestation, reducing fire risks, and restoring vital ecosystems. This funding allows us to scale our impact in ways never before possible."
Tenzin Seldon, Founder and Managing Partner of Pulse Fund, emphasized the urgency of Mast’s work:
"With wildfires worsening, supporting Mast was a clear choice. Their approach to forest restoration is ambitious, holistic, and exactly what’s needed to protect vulnerable ecosystems."
Chamath Palihapitiya, Founder and CEO of Social Capital, echoed this sentiment:
"In a market full of uncertainty, Mast delivers real, measurable impact. I don’t believe in every carbon credit, but I believe in the work Mast is doing."
Scaling the Future of Carbon Removal and Reforestation
The funding round also saw participation from Elemental Impact, Spero Ventures (with Tesla co-founder Marc Tarpenning as board observer), Thistledown Capital, and former FCC Chairman Julius Genachowski.
Several reinvestors, including Gaingels and Climate Avengers, also returned to support Mast’s next phase of growth.
With an estimated 2.3 million tonnes of dead trees from wildfires in Montana alone, Mast sees biomass burial as a scalable and immediate carbon sequestration strategy.
The company continues to lead in carbon-financed reforestation efforts, producing 36 million seedlings annually through its nurseries, Silvaseed and Cal Forest, which are critical to wildfire recovery in the western United States.
As Mast pushes forward with its vision, the Series B funding ensures the company can continue pioneering nature-based climate solutions that not only remove carbon from the atmosphere but also rebuild resilient forest ecosystems for future generations.
