Aalo Atomics is an Austin, Texas nuclear-energy company building small, factory-manufactured reactors designed to deliver firm, clean power to the loads that need it most, above all AI data centers. Founded in 2020, Aalo takes inspiration from the manufacturing playbooks of companies like Tesla and SpaceX, several of whose alumni it has recruited, betting that the path to cheap nuclear is not bespoke megaprojects but standardized, mass-producible reactor units built in a factory and shipped to site.
The company's flagship product is the Aalo Pod, a roughly 50 MWe power plant purpose-built for data centers. Rather than selling a single reactor, Aalo packages multiple of its sodium-cooled reactor modules into a complete, co-located power plant designed to sit alongside the compute it powers. The use of liquid-sodium cooling and a compact, replicable design is aimed at simplifying construction, improving safety margins, and driving electricity costs toward an aggressive target near 3 cents per kilowatt-hour.
Aalo's strategy is tightly coupled to the AI build-out. As hyperscalers and AI developers race to secure gigawatts of reliable, low-carbon power and find the existing grid unable to connect new load fast enough, behind-the-meter nuclear becomes attractive. Aalo aims to deliver dedicated, dispatchable power plants on timelines and at costs that make them a credible alternative to waiting in grid interconnection queues. In a significant milestone, the company unveiled a critical test reactor at Idaho National Laboratory, demonstrating progress from design toward hardware.
Aalo has raised roughly $136 million in total, including a $6 million seed in 2020, a $30 million Series A in 2024, and a $100 million Series B in 2025 led by Valor Equity Partners. The funding accelerates reactor development, factory build-out, and the path toward commercial deployment. While advanced-reactor commercialization carries substantial regulatory and engineering risk, Aalo is positioned at the center of the convergence between the AI energy crunch and the resurgence of nuclear power.
