Mast Reforestation, a Seattle, WA-based post-wildfire reforestation company, raised $25M in Series B funding.
The round was co-led by new investor Pulse Fund and existing investor Social Capital with participation from Seven Seven Six, Elemental Impact, Spero Ventures, with Tesla co-founder Marc Tarpenning as board observer, Thistledown Capital, Julius Genachowski, former Chairman of the U.S. Federal Communications Commission, Resilience Reserve, Gaingels, Climate Avengers, Climate Capital, Techstars, Drone.vc, Asymmetry Ventures and Massive Capital Partners.
The company intends to use the funds to scale its expansion into biomass burial—also known as Biomass Carbon Removal & Storage (BiCRS)—an emerging durable and scalable carbon removal solution that Mast is integrating with its restorative reforestation services.
Led by CEO Grant Canary, Mast develops a restorative carbon removal approach that combines resilient forest restoration with durable biomass burial to remove carbon from the atmospheric cycle. It owns and operates two of the largest wild tree seed and seedling nurseries in the West, 150-year-old Silvaseed and Cal Forest.
Mast is launching its first restorative biomass burial project, Mast Wood Preserve MT1, in central Montana. Since its founding, the company has restored thousands of acres across California, Montana, and Oregon.
