Aalo Atomics, a start-up based in Austin, Texas, closed a $100 million Series B financing round led by Valor Equity Partners, with participation from Fine Structure Ventures, Hitachi Ventures, NRG Energy, Tishman Speyer, and several others. The funding will support construction of Aalo-X, the company’s first advanced nuclear power plant, which aims to reach zero-power criticality next summer. If successful, it could be the first new nuclear plant to start up in the U.S. in decades.
The Aalo-X project will also co-locate an experimental data center, marking the first time a nuclear plant and a data center have been built together. The company positions this as a proof-of-concept for powering hyperscale and AI-driven workloads directly with factory-manufactured nuclear power. Its roadmap includes deploying “Aalo Pods” — clusters of small, mass-producible reactors designed to supply clean, continuous power at the scale data centers require.
Founded in 2023 by Matt Loszak, Aalo has rapidly built a 40,000-square-foot pilot factory and a non-nuclear prototype. The company argues that speed is critical to overcoming nuclear’s reputation as “too slow” and intends to expand beyond data centers into industrial heat, desalination, and municipal utilities. Longer term, it plans a 10x more powerful reactor design to drive electricity costs toward 3 cents per kWh.
- $100M Series B led by Valor Equity Partners with wide investor participation
- First Aalo-X nuclear plant targeting criticality in summer 2026
- Experimental data center co-located with plant for demonstration use
- Plans for factory mass-manufactured “Aalo Pods” to scale data center power
- Expansion roadmap includes industrial, municipal, and global applications
“Our latest financing gives us the capital to build Aalo-X and prove nuclear is the fastest, cleanest, and most reliable way to power AI,” said Matt Loszak, CEO of Aalo Atomics.
🌐 Analysis: AI data centers are pushing energy demand to levels that traditional renewable and grid sources struggle to meet. Nuclear co-location offers round-the-clock power without land and water intensity, solving a key constraint for hyperscalers. Aalo joins peers like Kairos Power, TerraPower, and Oklo in pushing modular, mass-manufactured nuclear as a solution for AI infrastructure. Unlike traditional gigawatt-scale plants, Aalo’s model targets direct alignment with hyperscale demand, potentially creating a new market segment where power plants are built around data centers rather than the other way around.
