Deep Fission

Deep Fission is leading advanced nuclear energy forward by overcoming its greatest historic
barrier: cost. Traditional nuclear plants take a decade or more, cost billions, and require
sprawling sites that are difficult to permit and finance. Our approach is vastly different, and we
expect it to be 80% cheaper. We deploy proven pressurized water reactors in a radically new
format — compact, modular units installed a mile underground using established drilling
techniques. This innovation is designed to reduce construction complexity, accelerate timelines,
and cut upfront costs.
Because our reactors are factory-built, repeatable, and deep underground, they can be installed
in as little as six months from groundbreaking to operation, setting a new standard for speed
and scalability. This would enable nuclear to grow like other forms of clean infrastructure,
rather than being confined to a handful of mega-projects.
Unlike many advanced concepts that rely on unproven fuels, untested designs, or new
regulatory frameworks, Deep Fission leverages what already works: an established reactor
design, readily available low-enriched uranium (LEU) fuel, and existing supply chains and
regulatory pathways. This aims to keep technical and regulatory risk low while enabling faster
deployment.
Our system uniquely combines three mature, proven technologies — oil and gas drilling,
geothermal heat transfer, and conventional nuclear systems — to simplify supply chains and
unlock scalability.
In short, we are revolutionizing the energy landscape with technology designed to be the
safest, most scalable, affordable, and rapidly deployable in the industry

Over the past 12 months, Deep Fission has achieved a series of breakthroughs that
fundamentally advance our mission to deliver low-carbon, scalable, cost-effective nuclear
power. Chief among them: we were selected by the U.S. Department of Energy (DOE) for its
Reactor Pilot Program, targeting criticality by July 4, 2026. This recognition provides us with
federal support, technical collaboration, and a streamlined path toward demonstration,
dramatically accelerating our timeline and positioning Deep Fission among the leading
innovators shaping the future of nuclear power.
We announced a landmark partnership with Endeavour Edged Energy data centers to provide 2
gigawatts (GW) of clean energy for its sustainable infrastructure.
We also raised $30M in financing through a go-public transaction. This capital infusion positions
Deep Fission to expand our team, accelerate progress toward demonstration in the DOE Pilot
Program, followed by expected commercialization quickly after.
Finally, we recently announced initial planned sites in Texas, Utah, and Kansas for the codevelopment of nuclear projects. These commitments highlight our ability to move quickly from
concept to siting and establish a blueprint for broader national deployment.
