In this episode of the Wealthing Podcast, host Alicia Castillo Holley speaks with Aaron Fitzgerald, a three-time founder and carbon removal entrepreneur reimagining how we manufacture the materials that shape our world. As CEO of Mars Materials, Aaron leads a team of “Planeteers” working to embed captured carbon into industrial supply chains—unlocking a trillion-dollar market opportunity while securing critical resources like freshwater and clean materials for transportation and energy.

Aaron shares his journey from growing up in poverty to working in the U.S. Senate, and ultimately building a climate tech company backed by organizations like Breakthrough Energy and Shell. He opens up about the personal and professional turning points that shifted his focus from profit to purpose, and how a chance moment at Lake Tahoe reframed his relationship to opportunity and legacy.

The conversation highlights Mars Materials’ breakthrough in developing a sustainable, cost-competitive form of acrylonitrile—an essential chemical used in carbon fiber and water treatment—alongside a major partnership with industry leader SNF. Alicia and Aaron also reflect on capitalism as a force for good, the role of storytelling in innovation, and the importance of thinking beyond business.
