Hexium is modernizing America’s isotope enrichment capabilities to power the next generation of advanced fission and fusion systems. We are building a reliable, scalable, and secure domestic supply of critical isotopes—starting with lithium-6 and lithium-7—using a reinvented form of Atomic Vapor Laser Isotope Separation (AVLIS). Building on foundational work from Lawrence Livermore National Laboratory, Hexium integrates state-of-the-art laser systems, beam propagation physics, precision optics, high-vacuum engineering, advanced controls, and industrial-scale manufacturing to bring isotope enrichment into the 21st century. Our multidisciplinary team includes leaders in laser physics, photonics, nuclear engineering, electrical engineering, automation, power electronics, and scientific instrumentation working hands-on to solve some of the most complex problems in clean-energy hardware. Hexium’s mission is simple and urgent: Enable the nuclear technologies that will power a cleaner, safer, more resilient future. We are actively hiring engineers, scientists, and technical experts who want to build real hardware with real impact.

Glaciers mission is to end waste. Sound ambitious? We agree. But the UN estimates that we only have until 2030 to change our consumption patterns before we do irreversible damage to the environment, so we’re of the opinion that now is the time for big bets. We’re starting in the world of recycling, which has a huge opportunity for impact. Americans send 1.4 million tons of waste to recycling facilities every week (that’s about 4 Empire State Buildings, or 1.5 Golden Gate Bridges). We’re also really bad at it: 25% of what we put in our recycling bins isn’t even recyclable. These recycling facilities make a living by sorting our jumbled-up waste and they need to do it cheaply and accurately. Otherwise they go out of business and our recycling goes straight to the landfill. Even so, recycling facilities today use processes that are highly manual, expensive, and error prone. We plan to revolutionize the way these facilities use technology, to make them more streamlined, accurate, and profitable - which means more recyclables avoid the landfill, and more of our natural resources are protected. Our growing team draws from the brightest and most passionate professionals across robotics, manufacturing, software, AI, and market strategy. We’re united by our deep-rooted passion to make a big environmental impact, and we’re looking for other mission-driven, creative thinkers to help us right the ship on this truly global issue.
