A new era of nuclear innovation with Jimmy Co-Founder Antoine Guyot

This episode of DeepTech Unleashed, hosted by Christian Noske, Partner at NGP Capital, explores the “new age of nuclear innovation” with Antoine Guyot, co-founder and CEO of Jimmy, a French company that designs and operates micro-nuclear reactors to provide industrial clients with decarbonized process heat at a lower cost than fossil fuels.

While Germany has historically been skeptical of nuclear energy, France is leading a shift toward a new generation of decentralised, micro-nuclear reactors. Antoine shares how Jimmy is decarbonising industrial process heat—a massive, often overlooked source of emissions—by designing and operating micro-reactors that provide low-cost, carbon-free energy directly to industrial sites.

Key topics discussed in this episode include:

The Nuclear Stigma: Why moving toward nuclear systems requires a “jump of faith” for a society that often only sees nuclear through the lens of cinema.

Decarbonising Industry: The challenge of replacing fossil fuels in industrial heating, which Jimmy addresses by providing carbon-free heat at a lower cost than traditional methods.

Nuclear as a Product: Jimmy’s innovative approach to making nuclear technology “simpler” and more accessible for industrial clients by treating it as a standard industrial tool rather than a massive infrastructure project.

Overcoming Deep Tech Challenges: Insights into the “moments of magic” and the hard-won breakthroughs necessary to scale a high-stakes energy startup.

The Future of Engineering: Why Antoine believes the fusion of nuclear physics and artificial intelligence will define the next decade of engineering breakthroughs.

About the Guest:

Antoine Guyot is the co-founder and CEO of Jimmy, a French company at the forefront of the new nuclear era. Backed by over €32 million in French government grants and €20 million in VC investment, Jimmy is proving that micro-reactors are a vital tool for achieving a decarbonised future.

Antoine graduated from Ecole Polytechnique, the top engineering school in France. After working in strategic consulting, he became interested in the nuclear field, particularly in how cheap uranium could help decarbonise industrial heat, which is mostly generated using fossil fuels. Jimmy’s mission is to provide industrials with cheap, decarbonised process heat, thus massively helping to decarbonise industries in France and Europe.
