Aalo Atomics, a US-based nuclear technology company announced that it has raised $100 million in a Series B financing round, with proceeds aimed at building the company’s first nuclear power plant to meet the rapidly growing energy needs of AI.
Founded in 2023, Texas-based Aalo’s mission is to accelerate the adoption of nuclear energy as a sustainable, resource-efficient power source, supporting both the growth of AI and broader global energy needs.
Aalo reactors utilize modular design for rapid on-site assembly, metallic liquid sodium coolant for high energy output, and low-pressure systems for simplified safety. This combination enables co-located fleets capable of powering industrial loads or data centers efficiently and reliably.
The funding will enable Aalo to construct its first full-scale nuclear power plant, the Aalo-X, which is targeted to reach zero-power criticality next year. In addition to producing electricity, the new plant will feature an experimental data center built alongside it – marking the first such co-location in the US.
Aalo’s approach emphasizes factory mass-manufactured, fleet-deployed reactors that are quick to install, compact in land and water requirements, and clean. In just under two years, the company has built a 40,000-square-foot pilot factory and a full-scale non-nuclear prototype.
The company plans to initially serve the data center market before expanding into broader markets such as municipal utilities, desalination, and industrial process heat.
Aalo CEO and co-founder Matt Loszak said:
“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.”
The financing round was led by Valor Equity Partners, and also included participation from Fine Structure Ventures, Hitachi Ventures, Crosscut, NRG Energy, Vamos Ventures, Tishman Speyer, Kindred Ventures, 50Y, Harpoon Ventures, Crescent Enterprises, Alumni Ventures, MCJ, Gaingels, Perpetual VC, and Nucleation Capital.
