Shantanu Agarwal and the $50 Million Case for Rock Dust
He helped build a machine to take carbon out of the air. Then the Sustaera co-founder found another route through the problem: crushed volcanic rock, small farms, and a customer who never gets the bill.
James Kanoff
James Kanoff is the co-founder and CEO of Terradot, a climate company using enhanced rock weathering to pull carbon dioxide out of the atmosphere by spreading crushed silicate rock across farmland. He launched Terradot in 2024 with $58.2M in funding, including a $54M Series A led by Kleiner Perkins and backing from Google, Microsoft, John Doerr and Sheryl Sandberg, and has already signed some of the largest carbon-removal deals in the field's history. Before Terradot, while a Stanford undergraduate sent home during the COVID-19 pandemic, he co-founded The Farmlink Project, a nonprofit that has rescued well over 130 million pounds of surplus food for communities facing hunger.
Kurt Tsuo
Kurt Tsuo is the Chief Business Officer of Varaha, a Gurugram-based carbon removal company building high-integrity credits with smallholder farmers across Asia and Africa. A Harvard-trained economist who spent seven years in agriculture before it was a climate headline, he has built business lines at the Gates Foundation, Farmer's Business Network, ProducePay, and Breakthrough Energy, and co-founded the carbon storage startup Graphyte. His through-line is unglamorous and stubborn: make the economics of fixing carbon work for the people who actually grow food.
