Make nuclear boring. On purpose.
Most nuclear founders sell you the future: a reactor that runs on something exotic, cooled by something clever, decades from a permit. Bret Kugelmass sells you 1968. His company, Last Energy, builds a 20-megawatt pressurized water reactor using physics the industry settled half a century ago, then ships it in modules that bolt together on a concrete pad. The radical part is not the machine. It is the refusal to reinvent it.
That refusal came from homework. Before Last Energy raised a dollar of construction money, Kugelmass sat behind a microphone for the Titans of Nuclear podcast and worked through more than 800 interviews with engineers, regulators, operators, and executives. Somewhere in that marathon he counted dozens of next-generation startups chasing novel reactor designs, and he noticed they kept tripping over the same root. The cost was not the steel. It was the calendar. When a megaproject takes a decade, interest on borrowed money piles up until it swallows the economics. By his accounting, roughly 60 percent of nuclear's levelized cost is the bill for time.
"We're innovative in the way that we are not trying to be overly innovative. We don't reinvent the reactor core, the physics, the chemistry or the materials."
So Last Energy attacks the calendar. Standardize the unit, build it in a factory, truck it to the site, and finance it the way you finance a wind farm rather than a cathedral. The fuel is off-the-shelf. The footprint is small enough to park next to a steel mill, a data center, or a campus. The first paying customers were lined up in the United Kingdom, Poland, and Romania - markets hungrier for fast nuclear than the slow-permitting US. Then the company planted its flag in Texas.
Kugelmass did not arrive from inside the nuclear priesthood. He grew up in Nassau County on Long Island, studied math at Stony Brook, then took a master's in mechanical engineering and robotics at Stanford in 2011. He built a Lunar Rover control device at NASA. He founded a drone company, Airphrame, ran it for about five years, and sold it to one of its own customers. By the time he turned to atoms, he had already learned the lesson he now repeats to anyone starting out: fall in love with the customer's problem, never the solution.
