Last Energy Tech Stack

Micro modular nuclear reactor developer scaling manufacturing and licensing

Nuclear Electric Power Generation Austin, Texas 51–200 employees Founded 2019 Privately Held

Last Energy develops small modular reactors (SMRs) to reduce nuclear construction timelines and costs. The stack reveals a hardware-first engineering operation: ANSYS Fluent, STAR-CCM+, OpenFOAM, SolidWorks, Revit, and AutoCAD dominate, paired with manufacturing tools (Mastercam, Fusion 360) and process-control systems (PLC, HMI, Six Sigma, FMEA). Active projects span reactor safety analysis, component lifecycle management, and international licensing—alongside finance infrastructure (debt offerings, project finance, month-end close), indicating a capital-intensive commercialization phase. Hiring skews senior engineering and finance, suggesting they're past prototyping and now executing regulatory and fundraising workstreams in parallel.
