PRESS RELEASE — Aalo Atomics, the company building fully modular nuclear plants to power modern AI data centers, has secured $100M in Series B funding led by Valor Equity Partners with participation from new and existing investors including Fine Structure Ventures, Hitachi Ventures, NRG Energy, Vamos Ventures, Tishman Speyer, Kindred Ventures, 50Y, Harpoon Ventures, Crescent Enterprises, Crosscut, Alumni Ventures, MCJ, Gaingels, and Nucleation Capital, among others. Aalo has raised more than $136 million to date and is moving at lightspeed for a nuclear company, completing its first full-scale non-nuclear prototype earlier this year with plans to finish construction on its first extra modular nuclear reactor (XMR) in 2026.
“The world’s leading technology companies, as well as state and federal governments, see nuclear energy as a crucial component to powering the AI data centers of the future, as evidenced in recent legislation from forward-thinking states like Texas and Idaho and multiple Presidential Executive Orders,” said Matt Loszak, Co-founder and CEO, Aalo Atomics. “Our unique approach of mass manufacturing modular nuclear plants, combined with our commitment to both safety and scalability, positions us at the forefront of this movement and ensures we are ready to meet this imminent market need at record speed.”
Aalo will use its new financing to double the size of its team, growing from roughly 60 employees to over 120 in the next year, with a focus on acquiring premium engineering and manufacturing talent. In addition, Aalo has added several well-known executive leaders to its team in recent weeks, with deep expertise in public policy, regulatory environments, nuclear technology, and manufacturing. They include:
- Jimmy Glotfelty, former commissioner for the Public Utility Commission of Texas
- Bryson Gentile, former head of manufacturing on Falcon 9 at SpaceX
- Pete Gaillard, former head of regulatory affairs for TerraPower
- Nick Touran, formerly with TerraPower and founder of “What Is Nuclear?”
“AI is expected to require triple digit increases in the power supply in the coming months and years, creating both a complex problem for U.S. industry and a significant commercial opportunity for the companies that can solve it,” said Antonio Gracias, founder and CEO of Valor Equity Partners. “We believe Aalo, with its advanced XMR technology, rich manufacturing expertise and highly experienced team, is well positioned to capture this market opportunity, and has already shown its ability to innovate, forge key industry relationships and move extremely quickly. More broadly, we believe that energy supply represents a current constraint and key strategic imperative for the country, and are proud to align ourselves with the innovators who are helping secure our nation’s energy resilience in the face of this massive surge in demand.”
Additional recent Aalo milestones include:
- Aalo was selected by the DOE to test the Aalo-X experimental XMR power plant at Idaho National Laboratory (INL) under President Trump’s Nuclear Reactor Pilot Program, with a target of criticality by July 4th, 2026.
- Aalo has completed a comprehensive Conceptual Design Review for Aalo-X involving over 40 experts, securing official site allocation from DOE-ID, and receiving an Environmental Assessment Determination from the DOE, which expedites the environmental review process.
- Unveiling of 40,000 square foot manufacturing plant in Austin, Texas in April.
- Selection as one of four partners to develop up to 1 GW of nuclear energy generation capacity at the Texas A&M RELLIS Campus.
- Purchase of land in Texas to deploy a non-nuclear prototype where it can test all elements of its design, including using sodium for coolant. Construction is underway.
Aalo’s flagship product is the Aalo Pod, a 50 MWe XMR power plant purpose-built for data centers. Each Aalo Pod contains five Aalo-1 reactors, is fully modular (both the reactor and the plant) and can scale seamlessly to gigawatts. With a small physical footprint and no need for external water sources, the Aalo Pod is easy to collocate onsite with the data center. Aalo-1 reactors are sodium-cooled and use proven-safe, readily available low enriched uranium fuel (LEU+, UO2).
