Clay DUMAS
-
Clay is a founding partner at Lowercarbon Capital, where he works closely with unreasonably ambitious founders to reduce CO2 in the atmosphere. He is also a partner at Lowercase Capital, one of the industry’s highest-performing early-stage venture funds. Previously, Clay served as an aide to the Senior Advisor and the Deputy Chief of Staff in the Obama Administration. His work spanned operations and security to media and political strategy. He later helped rebuild the Office of Digital Strategy. Part of his mandate was to reinvigorate how the White House built online support for its conservation, energy, and other planet-healing initiatives.
Philippe VERCHERIN
-
Philippe is Investment Director at Crédit Mutuel Impact since 2020. He focuses on investments in innovative companies with high environmental impact and in infrastructure for the energy transition. He previously spent eight years at VINCI, a world leader in concessions, energy and construction, financing major highway and railway projects through public-private partnerships. Philippe holds a Master of Science in civil engineering from Ecole Nationale des Ponts et Chaussées and an MBA from Collège des Ingénieurs.
Francesco VOLPE
-
Francesco co-founded Renaissance Fusion in 2020 after 24 years of physics research in Frascati, Garching, Culham, San Diego, Madison and New York. His accolades include the 2003 Otto Hahn Medal for his PhD on Wendelstein 7-AS, and the 2011 DOE Early Career Award for the first stabilization of a “Locked Mode” -the main cause of tokamak disruptions. As one of few physicists with direct experience on stellarators, tokamaks and spherical tokamaks, he concluded that HTS stellarators with liquid walls are the most viable, efficient reactors, but they need to be simplified, shrunk and made economically attractive. With that in mind, in 2019 he earned an Executive MBA from ESCP Europe. Until 2025, Francesco was also the inaugural CEO of Renaissance, which he grew to 100 people, over € 60M of funds raised, and 3 locations in 2 countries.

Nathaniel is an experimentalist in fluid mechanics. He earned his PhD in 2017 from the University of Grenoble (FR) and Coventry University (UK). For that, he experimentally showed that liquid metal turbulence subject to strong magnetic fields can sustain inverse energy transfers at scales which are topologically 3D (see PRL article). As a post-doc at ONERA (the French aerospace laboratory), he benchmarked a novel method to reconstruct the full pressure field from tomographic velocity measurements alone. He joined Renaissance Fusion in 2021 when the lab was still an empty hall. He made major contributions to the Skyfall series of experiments in meter-size cylindrical chambers and was promoted to Group Leader in 2023 and Head in 2025.
