Aug 2025Series BAlumni Ventures (lead); Valor Equity Partners (lead)$100MAalo Atomics, a Texas-based nuclear technology company founded in 2023, develops fully modular nuclear plants designed to power AI data centers using advanced XMR technology and factory-made reactors. The company closed a $100 million Series B funding round on August 19, 2025, led by Valor Equity Partners with participation from Alumni Ventures, 50Y, Fine Structure Ventures, Hitachi Ventures, NRG Energy, Vamos Ventures, Tishman Speyer, Kindred Ventures, Harpoon Ventures, Crescent Enterprises, Crosscut, MCJ, Gaingels, Perpetual VC, Nucleation Capital, and others. This brings total funding to over $136 million. The proceeds will fund construction of Aalo-X, the company's first nuclear power plant at Idaho National Laboratory, targeting criticality in summer 2026 and paired with an experimental data center to demonstrate nuclear power for AI workloads. Aalo plans to scale to Aalo Pods, each comprising five Aalo-1 reactors and one turbine for 50 MWe output, aimed at data centers with long-term goals of electricity costs at 3 cents per kWh to compete with renewables and natural gas. Aalo, led by CEO Matt Loszak, will double its team from 60 to over 120 employees, focusing on engineering and manufacturing talent, and has added executives with expertise in nuclear technology, policy, and regulation. The round reflects growing investor interest in nuclear for AI energy demands, positioning Aalo among startups selected for the U.S. Department of Energy’s Nuclear Reactor Pilot Program.
Aug 2024Series AFifty Years (lead)$27MAalo Atomics is an Austin, Texas-based nuclear energy startup developing the Aalo-1, a micro modular nuclear fission reactor designed for factory production to enable low-cost, rapid deployment of clean baseload power for applications including data centers, military, and developing regions. The company raised $27 million in its Series A funding round in August 2024, led by 50Y (Fifty Years), with participation from Valor Equity Partners, Harpoon Ventures, Crosscut, SNR, Alumni Ventures, Preston Werner, Earth Venture, Garage Capital, Wayfinder, Jeff Dean, Nucleation Capital, and others. This followed a $6.26 million seed round in 2023, bringing total funding at that point to approximately $33 million. The Series A funds are earmarked for accelerating reactor development, including hiring to double staff from 15 to 30 in areas like manufacturing, sales, EPC, fuel, engineering, finance, and product development. Key milestones around the Series A include signing a siting MOU with the Department of Energy in May 2024 for deploying an experimental Aalo-X reactor at Idaho National Laboratory, and submitting a Regulatory Engagement Plan to the Nuclear Regulatory Commission in June 2024. The REP outlines completing plant design and safety cases by December 2025, submitting a Combined License Application in June 2026, with target approval by June 2028 and operation by 2029. Post-Series A, Aalo Atomics continued rapid progress, securing selection for the DOE’s Nuclear Reactor Pilot Program and raising $100 million in a Series B round in August 2025 led by Valor Equity Partners, with participation from prior investors including 50Y and new ones like Hitachi Ventures, NRG Energy, and Tishman Speyer, bringing total funding over $133-136 million. The Series B supports aggressive goals like beginning construction on small modular reactors soon after and achieving criticality by mid-2026 under executive orders, with plans for the Aalo Pod—a 50 MWe power plant with five Aalo-1 reactors—targeted for data centers.
