First Mode started by removing the diesel engine from a colossal mining truck and replacing it with a hydrogen fuel cell powerplant. A world-first, and the world’s largest. But we’re not stopping there. We are also working on providing critical mine site infrastructure for hydrogen production, battery recharging, and hydrogen refueling. Today, we’re starting at the source, the mining industry, and tomorrow the larger supply chain, to completely eliminate the use of diesel and speed the clean energy transition. We hope you’ll join us in building a brighter future for people and planet.

DroneSeed offers full lifecycle services for forestry management by using an efficient, cost-competitive fleet of drones to reduce reliance on manual labor. Our mission is simple: Make reforestation scalable to mitigate the worst effects of climate change. DroneSeed is transforming a 300-million-acre global landscape deforested since the 1990s. It would take 300 years to replant this deficit with current tools. Our technology speeds up the process. DroneSeed uses heavy-lift drone swarms to reforest at scale after fires. We cut time to reforest from 3 years to 3 months. We’ve pioneered the drones and the backend required to operate swarms as a delivery solution over rough terrain. We survey sites and deliver to targeted areas of soil proprietary seed vessels that boost seed survival. Utilizing carbon credits, we double landowner investment in 18 months addressing the financial barriers to reforestation. DroneSeed has acquired and expanded Silvaseed, a 130-year old business which grows millions of trees per year, to become the largest private tree seed bank west of Colorado. The acquisition positions DroneSeed as a one-stop-shop for reforestation services including seed collection, seedling cultivation, aerial drone-based seeding, and financing with carbon credits. DroneSeed plans to further expand, doubling its capacity to address increased demand for reforestation services.
