Aalo Atomics.

Aalo Atomics builds nuclear power plants on a production line. The flagship product is the Aalo Pod, a 50-megawatt-electric plant purpose-built for data centers. Instead of pouring a bespoke plant into the ground over a decade, Aalo manufactures reactor modules in a factory and assembles them on site. The target is electricity at three cents per kilowatt-hour.

The company runs a 40,000-square-foot pilot factory and headquarters in Austin, Texas, with a second office in Idaho Falls. Aalo-X, its 10-megawatt-electric experimental plant, was unveiled at Idaho National Laboratory in 2026. By the company's account, it is the first new reactor at the lab in fifty years. Initial criticality is the next milestone on its roadmap.

What they're building

The Pod is cooled by liquid metal, which pulls heat from the core faster than water or gas. By the company's numbers, the design extracts up to ten times more energy than other nuclear technologies of a similar physical size. Safety rests on passive systems. The plant can remove decay heat for 72 hours without power, and shutdown relies on diverse, independent mechanisms. The core itself has inherent negative reactivity.

The manufacturing discipline shows in the sequence. Before fueling anything, Aalo built Aalo-0, a full-scale non-nuclear prototype, to surface assembly problems while they were still cheap. Aalo-X is the critical test reactor, and the Pod is the product. The stated next step is the Aalo Gigawatt Factory, where modules come off a production line at scale.

Why we backed the founders and team

Nuclear's problem sits in construction rather than physics. Every plant has been a one-off civil-engineering project, and every overrun has run a decade. Aalo treats the reactor as a manufacturing problem and moves the work from the construction site to the factory floor, where tolerances tighten and unit costs fall with volume. That is assembly, and it is the kind of compounding advantage we look for.

The demand already exists. Data centers need firm, clean power in 50-megawatt increments, sited where the load is. The work between here and that grid is licensing, fuel, coolant handling, and yield on a factory line, the long middle where nothing demos well. Aalo is built for that stretch. The prototype is assembled and the test reactor stands at Idaho. A factory is tooling up behind them.
