MCJ invests in Aalo extra-modular nuclear reactors

MCJ has joined Aalo’s $100 million Series B led by Valor Equity Partners to back Aalo’s factory-manufactured extra-modular nuclear plants for data centers.

• Primary announcement: MCJ joined Aalo’s $100 million Series B (led by Valor Equity Partners) to support Aalo’s factory-produced 50-megawatt pods (five 10-megawatt reactors, “XMRs”). Aalo operates a vertically integrated factory in Austin, aims for 52-week deployment timelines for data-center sites, and celebrated the Aalo-X groundbreaking beside INL; Aalo is one of 11 companies selected to the DOE President’s Nuclear Reactor Pilot Program targeting at least three test reactors by July 4, 2026.
• Background and regulatory context: Founders and senior leaders include Matt Loszak (CEO, serial entrepreneur), Yasir Arafat (CTO, led MARVEL and Westinghouse eVinci work, achieved DOE reactor authorization in ~30 months), and Jon Guidroz (SVP, former Director of Energy at Microsoft/Google/AWS). The article cites May 2025 executive orders driving 18-month NRC review timelines, designation of AI data centers as ‘critical defense facilities’, a 400 GW nuclear target by 2050, and references the DOE’s $900M SMR program that benefits Aalo’s commercial pathways.
