We’re on a journey to Grow the Future of Materials. How? By unlocking the unique properties of mycelium, the root structure of mushrooms. Our patented technology, Fine Mycelium™, unleashes a new class of materials crafted from nature, engineered for performance, and built for a resilient future. Our impact on future generations steers our innovations today. From our expertise in mycology and materials science to our manufacturing innovations, we’re creating new possibilities for industry. We’re an outstanding team of scientists, engineers, product experts, artists, leaders—and you.

Fungi Perfecti® - makers of Host Defense® Mushrooms™ - is a family-owned company specializing in mushroom mycelium-based supplements. Founded by Paul Stamets in 1980 with the goal of building a bridge between people and fungi, Fungi Perfecti® has become synonymous with cutting-edge mycological research and innovative mycological solutions. Under Paul’s visionary leadership, we have made significant breakthroughs revealing the power and potential of mushroom mycelium. This is the foundation of the Host Defense® brand. Based near the Olympic Rainforest in Washington state, we are one of the best-documented and longest-standing mushroom supplement companies in the USA. Since its inception, Fungi Perfecti® has been the industry leader in research on the endless potential for the use of fungi in everything from water filtration (mycofiltration) and ecological rehabilitation (mycoremediation), to using beneficial mushrooms in the form of supplements to support human health. Our continued mission is to explore, study, preserve, and spread knowledge about the use of fungi for helping people and planet.* *These statements have not been evaluated by the Food and Drug Administration.

Livelihoods is a global initiative that connects companies, local organizations and communities to turn climate ambition into tangible action. We are grounded in a core belief: there is no environmental impact without social justice. Since 2009, we’ve mobilized private investment and field expertise to co-design and deliver long-term projects that restore natural ecosystems, improve livelihoods, and strengthen resilience. With a team of 50 specialists and over 15 years of experience, we operate across two impact platforms: within value chains, we help companies transition to regenerative sourcing through the Livelihoods Fund for Family Farming and custom programs; beyond value chains, our three Livelihoods Carbon Funds drive nature-based solutions that restore degraded land, expand agroforestry, and improve energy access — generating high-quality carbon credits certified by international standards such as Gold Standard or Verra. Our approach is non-speculative and outcome driven. Backed by 20 committed companies and led by Livelihoods Venture — a social business owned by our foundation — we’ve launched 47 large-scale projects, delivering 4.8 million tons of CO₂ reductions and removals, planting 159 million trees, and improving life for 2.4 million people in Africa, Asia, Europe and Latin America.
