Barclay Rogers

Barclay Rogers is the co-founder and CEO of Graphyte, a carbon removal company that turns waste biomass into dense, dehydrated carbon blocks and buries them to keep CO2 out of the atmosphere for over a thousand years. A former environmental lawyer and mechanical engineer turned multi-time agtech and climate founder, he built Graphyte's 'Carbon Casting' process to deliver durable carbon removal at under $100 a ton, an order of magnitude cheaper than direct air capture. The company is backed by Bill Gates' Breakthrough Energy Ventures and runs its first commercial plant in Pine Bluff, Arkansas. Rogers also teaches a climate change solutions course as an adjunct professor of law at Tulane University.

Kurt House

Kurt Zenz House is the Co-Founder and CEO of KoBold Metals, an AI-driven mineral exploration company backed by Bill Gates, Jeff Bezos, and Andreessen Horowitz. A Harvard-trained earth scientist and serial energy entrepreneur, he built KoBold from the ground up to solve one of the most consequential problems of the energy transition: finding enough copper, cobalt, lithium, and nickel to power a decarbonized world. Under his leadership, the company discovered the Mingomba deposit in Zambia - potentially the most significant copper find in a century - and raised over $1 billion to develop it. Before KoBold, he founded C12 Energy (CO2-based enhanced oil recovery) and Phase Change Resources (natural gas asset acquisition), and held research and teaching roles at MIT and Stanford.
