Co-Founder, CTO (Next-Gen Geothermal)

Marble is a climate tech venture studio. We partner with scientists, engineers, and operators to create companies solving hard climate problems in the world's largest industries.

Our first 13 companies are building transformative products across energy, industry, agriculture, and climate resilience. 100% have been successful in raising follow-on to date. We are looking to partner with exceptional individuals to create our next venture.

Electricity demand is projected to rise sharply over the next decade, requiring new generation capacity at a pace well beyond today’s build rates. In the US alone, rapid load growth is expected to reach 25% by 2030, driven by electrification, data centers, AI infrastructure, and industrial buildout. This demand explosion calls for a massive increase in clean firm power, which next-generation geothermal is uniquely positioned to provide.

Despite the vast availability of geothermal heat, most remains inaccessible. Many geothermal reservoirs, especially those in low-permeability or geologically complex settings, cannot deliver sufficient flow using conventional vertical or mildly deviated wells. Most recently EGS has expanded the resource potential, but still remains constrained by technical limitations, such as water usage and thermal breakthroughs, high costs, and community and regulatory resistance due to concerns about induced seismicity. As a result, today’s projects tap only a small fraction of the subsurface, keeping geothermal below 1% of global electricity, despite IEA estimates of up to ~800 GW of potential by 2050.

We are building a next-generation geothermal company focused on deploying novel well architectures that significantly increase reservoir contact and heat extraction.

By enabling access to a larger effective rock volume, we are targeting 2–3× greater well productivity. Combined with disciplined drilling execution, this will allow us to drive down costs that lead us on a path to the $50/MWh LCOE target.

We have de-risked all fundamental technical aspects, initiated discussions with key technical partners, and identified potential site geographies for pilots and first-of-a-kind.

You’re encouraged to apply even if your background isn’t a perfect match. Above all, we value intelligence, creativity, and founder potential.

We believe that a diverse group of minds is key to solving the climate crisis. We encourage women and people of colour to apply. Studies have shown that under-represented candidates are less likely to apply for an opportunity unless they feel they meet every single qualification. We are committed to building a diverse, inclusive and mission-driven cohort. If you’re excited about the programme but your past experience doesn’t align perfectly with what you read on our website, we encourage you to apply anyways!
