Matthew Ciardiello

co-founder & cEO

Matt believes the greatest challenge of the 21st century is for humanity to find a way to live in equilibrium with planet Earth, and he knows that achieving a transition away from fossil fuels will be the most difficult part of the solution. As a career entrepreneur, executive, and principal investor in the energy industry with experience across the whole energy value chain, he understands the sheer scale of the energy transition challenge, the limitations of available technology, and the unyielding constraints of the laws of thermodynamics. But he is also optimistic about human ingenuity, and wants to dedicate his career and extensive experience and expertise to finding zero-emission-energy solutions. Matt is fascinated with energy storage systems, and he recognizes that grid-scale electricity storage is the key enabler of reliable renewable energy.

Matt has served as the founder and CEO of Poplar Resources, and previously worked for Magellan Petroleum, Mubadala, Arcapita, and Compass Partners. He graduated from Harvard with an A.B. in Classics and is a CFA charterholder. He currently lives in Fort Worth, Texas, with his family and is active on several non-profit boards.
