Industrial-scale isotope production for critical industries

Marathon was co-founded in 2023 by Adam Rutkowski, previously a Propulsion Engineer at SpaceX and PhD candidate in Plasma Physics at Princeton University, and Kyle Schiller, previously a Science Policy Fellow at Schmidt Futures.

We believed then, and now more than ever, that fusion is humanity's best path to abundant, clean and reliable energy.

Marathon is supported by $18m in funding across the US Department of Energy, Breakthrough Energy's fellows program and leading private investors.
