Hexium

Hexium Inc. (operating under hexium.com) is an early-stage deep-tech hardware and advanced manufacturing company at the forefront of laser science, plasma physics, and atomic engineering. Founded in October 2023 by Dr. Charlie Jarrott and emerging from stealth in early 2025 with $12 million in venture funding, the company is building next-generation isotope enrichment technology designed to fuel the modern nuclear renaissance, starting with lithium. Hexium specializes in modernizing and industrializing Atomic Vapor Laser Isotope Separation (AVLIS)—a highly advanced, laser-driven ionization and electric sorting process originally developed and de-risked with over $2 billion of investment by the U.S. Department of Energy (DOE) at Lawrence Livermore National Laboratory. By utilizing precisely tuned laser wavelengths to selectively ionize specific isotopes within a vaporized metal stream, Hexium separates critical isotopes like lithium-6 (vital for tritium breeding and radiation shielding in fusion machines) and lithium-7 (essential for fission reactor cooling systems) using targeted electric fields. Unlike legacy nuclear enrichment methods that rely on capital-intensive centrifuges, hazardous chemical agents, and produce significant environmental waste, Hexium's clean, patent-pending architecture achieves unmatched precision in a single-pass production cycle with a compact, scalable commercial footprint. Headquartered in Austin, Texas, where it operates specialized demonstration facilities, Hexium provides a domestic, secure, and cost-competitive supply chain for bottlenecked isotopes, mitigating geopolitical supply vulnerabilities and driving infrastructural breakthroughs across clean energy, advanced fission, fusion energy development, and nuclear medicine.
