US-based nuclear startup Aalo Atomics has raised $100 million in a Series B funding round to build its first advanced nuclear power plant, with a unique twist it will be co-located with a data center purpose-built for artificial intelligence (AI) workloads.

Powering the AI Boom with Clean Nuclear Energy

Founded in 2023 and headquartered in Texas, Aalo aims to accelerate the adoption of nuclear energy as a clean and scalable solution for the world's growing energy demands, particularly from energy-intensive AI systems. The company’s modular reactor design uses liquid sodium coolant for high efficiency and operates at low pressure, which simplifies safety systems and reduces costs.

Introducing the Aalo-X: A First-of-Its-Kind Facility

The new funding will support the construction of the Aalo-X, a full-scale nuclear facility expected to reach zero-power criticality in 2026. Alongside it, Aalo will launch an experimental data center, making this the first integrated nuclear-and-data infrastructure project in the United States.

Scalable, Resource-Efficient Design

Aalo’s vision revolves around factory-built, fleet-deployed reactors that are compact, quick to assemble, and require minimal land or water. In less than two years, the company has established a 40,000-square-foot pilot manufacturing facility and built a full-scale non-nuclear prototype to demonstrate feasibility.

Beyond Data Centers: Expanding the Market

While the initial focus is on powering AI and data infrastructure, Aalo intends to scale into other sectors such as municipal utilities, industrial process heat, and desalination. The company believes its modular approach is well suited for a wide range of high-energy-demand applications.

A Strong Vote of Confidence from Investors

The Series B round was led by Valor Equity Partners, with participation from a wide range of investors including Fine Structure Ventures, Hitachi Ventures, Crosscut, NRG Energy, Vamos Ventures, Tishman Speyer, Kindred Ventures, 50Y, Harpoon Ventures, Crescent Enterprises, Alumni Ventures, MCJ Collective, Gaingels, Perpetual VC, and Nucleation Capital.

CEO’s Vision: Nuclear as the Backbone of a Sustainable Future

Aalo co-founder and CEO Matt Loszak emphasized the urgency of nuclear adoption. “The world needs as much nuclear energy as we can get, as soon as we can get it. Not only because it’s the best way to power the acceleration of AI. But also because as costs come down, it will be the most sustainable and resource-efficient way to power almost everything.”
