Mast Reforestation
A Seattle company, formerly known as DroneSeed, that sells carbon removal credits to finance replanting of forests lost to wildfire in the Western United States, with its own seed bank, nurseries and FAA-approved heavy-lift drones. Its reforestation projects are developed under the Climate Action Reserve's Climate Forward program and its biomass-burial removal under Isometric. It raised a USD 36 million Series A in September 2021 (led by Social Capital and Seven Seven Six), USD 15 million in project financing from Carbon Streaming in May 2023 and a USD 25 million Series B in February 2025. Carbon Streaming wrote the fair value of two Mast projects, Sheep Creek (Montana) and Feather River Dome (Northern California), down to zero in its 2024 reporting after high seedling mortality. A wrongful-termination lawsuit by a former employee, reported on 8 June 2025, alleges the company overstated the value of forward-sold credits; the company disputes the allegations and says an independent investigation found no wrongdoing.
