When you think about the future of power, most folks picture wind farms spinning away or solar fields stretching across deserts. Aalo Atomics sees something different: nuclear microreactors rolling off an assembly line like Teslas, dropped into data centers that are choking on their own energy appetites. Today, Aalo Atomics locked in $100 million in Series B funding, led by Valor Equity Partners with a powerhouse crew of investors including 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. That puts their total raise north of $136 million in just two years.
The company isn’t just tinkering in the lab. Co-founders Matt Loszak and Yasir Arafat have built Aalo into a 60-person team with a 40,000 square foot manufacturing facility in Austin and research operations at Idaho National Laboratory. Yasir Arafat, who led the DOE’s MARVEL microreactor project, knows this playbook in his bones. Matt Loszak, who previously scaled Humi to acquisition, brings the execution muscle. Together, they’re betting that sodium-cooled, factory-built reactors are the missing puzzle piece for an AI infrastructure race that’s already rewriting power demand forecasts.
Consider the math. Each Aalo-1 reactor puts out 10 MWe, with five bundled into an Aalo Pod delivering 50 MWe on a footprint smaller than five acres. No massive water sources. No endless permitting gridlock. Just compact, modular units shipped like oversized Lego bricks, stacked into fleets that could scale from a single data hall to gigawatt cities of servers. The goal is electricity at three cents per kilowatt-hour. That number isn’t just competitive, it’s a sledgehammer against today’s fragile grid economics.
Momentum is building. Aalo completed its full-scale non-nuclear prototype, secured DOE site authorization for its Aalo-X experimental reactor, and cut a deal with Idaho Falls Power to deploy seven units totaling 75 MW. Texas A&M’s RELLIS Campus is exploring up to 1 GW of nuclear capacity. The DOE has tapped Aalo for its Nuclear Reactor Pilot Program, targeting zero-power criticality by summer 2026. For a company founded in 2023, that’s not just traction, it’s velocity.
The real story here is scale. Data center demand is expected to quintuple by 2035, climbing toward 176 GW. The small modular reactor market, pegged at $5.8 to $6.8 billion today, could push into the tens of billions by the 2030s. Aalo Atomics is positioning itself not as a boutique science project but as the factory that floods the market. Build dozens of reactors a year, expand to industrial and utility-scale deployments, and show the world that nuclear doesn’t have to be a fifty-year bet. It can be built, shipped, and turned on in months.
