Texas-based nuclear technology startup Aalo Atomics has raised $100 million in a Series B funding round to accelerate the construction of its first nuclear power plant, designed to meet the surging energy demands of artificial intelligence (AI).
Founded in 2023, Aalo Atomics is on a mission to advance the adoption of next-generation nuclear energy as a sustainable and resource-efficient power source. The company’s innovative reactor design focuses on modular construction, enabling rapid assembly on-site, while utilizing metallic liquid sodium coolant for higher energy output and low-pressure systems for improved safety.
First-of-its-Kind Nuclear Plant with Integrated Data Center
The funding will support the development of Aalo-X, the company’s first full-scale nuclear power plant, which is expected to reach zero-power criticality next year. In a pioneering move, Aalo Atomics will also build an experimental data center alongside the facility—marking the first nuclear-energy-powered co-located data center in the United States.
Aalo’s approach emphasizes factory mass-manufactured, fleet-deployed reactors that require less land and water, making them compact, clean, and scalable. Within just two years, the startup has established a 40,000-square-foot pilot factory and developed a full-scale non-nuclear prototype.
Targeting AI and Data Center Markets First
Initially, Aalo plans to serve the rapidly growing data center industry, which faces immense energy challenges driven by AI workloads. Beyond this, the company aims to expand into sectors such as municipal utilities, desalination plants, and industrial process heating—where clean, efficient nuclear power could play a transformative role.
Leadership and Vision
Commenting on the milestone, 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.”
Strong Investor Backing
The $100 million Series B round was led by Valor Equity Partners, with 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.
With this significant funding, Aalo Atomics is positioning itself at the forefront of the clean energy transition, aiming to deliver scalable nuclear power solutions that can sustain the AI revolution while meeting global energy needs.
