Michael Alexander is the co-founder and CEO of Addis Energy, a Somerville, Massachusetts startup turning the Earth's crust into a chemical reactor to make clean ammonia. A chemical engineer who spent more than eight years refining oil at Shell and Marathon Petroleum, he discovered geologic hydrogen at Harvard Business School and teamed up with classmate Charlie Mitchell and MIT professors Iwnetim Abate and Yet-Ming Chiang to commercialize a process that stimulates ammonia production from iron-rich rock underground. In December 2025 Addis raised an oversubscribed $8.3M seed round, bringing total funding to $17.3M.
Chris Abbott is the Chief Executive Officer of Pivot Bio, a Berkeley-based agricultural biotechnology company pioneering microbial nitrogen solutions that replace synthetic fertilizers. A Minnesota native and University of Minnesota graduate, Abbott built his career at the intersection of agriculture finance and agtech investing - from Wall Street sell-side research at Piper Jaffray to co-leading Continental Grain's Conti Ventures. He joined Pivot Bio's board in 2018, and in August 2023 stepped up as CEO, guiding the company past $100 million in annual revenue while scaling its gene-edited microbes to over 5 million acres. Under his leadership, Pivot Bio achieved 60% year-over-year revenue growth and has helped farmers reduce synthetic nitrogen use by over 129,000 metric tons.
Pivot Bio engineers nitrogen-fixing microbes that live on crop roots and feed corn, wheat, sorghum and small grains directly, replacing a portion of synthetic fertilizer with a biological alternative that does not volatilize into the atmosphere or leach into groundwater.
Hiro Iwanaga is the Co-Founder and CEO of Talus Renewables (TalusAg), the company behind the world's first commercial modular green ammonia production system. A Stanford-trained engineer-turned-investor-turned-builder, Iwanaga spent years at hedge funds like Baupost Group and Silver Point Capital before channeling a decade of philanthropic green ammonia research into a full commercial venture. His technology - containerized units that turn air, water, and renewable electricity into fertilizer - is now operating in Kenya and Iowa, cutting farmer fertilizer costs by 30-50% and proving that decentralized, zero-carbon ammonia production is not a distant dream but a deployable reality.
