Jason Aramburu is the cofounder and CEO of Applied Carbon, a Houston-based climate tech company building the world's first mobile, in-field biochar production machines that convert agricultural crop waste into permanent carbon storage - and improved soil - in a single pass. A Princeton-trained ecologist who first encountered biochar during field research in Panama, Aramburu has spent two decades building at the intersection of soil science, robotics, and carbon markets. Before Applied Carbon, he founded re:char (smallholder biochar in Kenya, backed by Gates Foundation) and Edyn (smart irrigation, Y Combinator W14), then invested in AI and energy startups at Baidu Ventures and Saudi Aramco Energy Ventures before returning to his original mission. Applied Carbon raised a $21.5M Series A in July 2024, backed by Microsoft Climate Innovation Fund, Congruent Ventures, and the Grantham Foundation, and won the $500,000 Wilkes Climate Launch Prize in September 2024.
Lesley Silverthorn Marincola is the founder and CEO of Angaza, a San Francisco-based B2B software company that powers pay-as-you-go financing for solar home systems and other off-grid products across emerging markets. A Stanford-trained product designer and mechanical engineer, she launched Angaza in 2010 after a course called 'Designing for Extreme Poverty' lit a fire she hasn't put out since. Today, Angaza's platform reaches over 5 million people across 50 countries, enabling low-income households to pay for life-changing energy products through weekly micropayments via mobile money — replacing kerosene lamps one $1 payment at a time. Her work earned Angaza the 2018 Skoll Award for Social Entrepreneurship and a TED stage appearance. She is a Forbes '30 Under 30' alum, Echoing Green Fellow, and World Economic Forum Young Global Shaper.
