Mast Reforestation, North America's leading post-wildfire reforestation company, announced a $25 million Series B funding round 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.

Co-led by new investor Pulse Fund and existing investor Social Capital with participation from the Series A co-lead Seven Seven Six, the investment accelerates Mast's work to restore forestland lost to high-severity wildfires across the Western United States.

Additional investors in the Series B round include 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, and Resilience Reserve.

Mast also welcomes reinvestment from several investor groups, including LGBTQ+ investors Gaingels, as well as sector-focused Climate Avengers and Climate Capital; and longtime supporters from Mast's beginning days in Techstars, Drone.vc, Asymmetry Ventures and Massive Capital Partners also participated in the round.
