Fluxnium Inc. has raised $7.0M in seed funding to build a new domestic supply of uranium - pulled from seawater rather than dug out of rock. Congruent Ventures, Constellation Technology Ventures, and Active Impact Investments backed the round.
Los Angeles-based Fluxnium Inc. has raised $7M in seed funding, led by Congruent Ventures, with participation from Constellation Technology Ventures and Active Impact Investments. The capital will support technology development, pilot testing and commercial scale-up.
Founded by Jeff Green and Jim McDermott, Fluxnium is taking a different route to uranium production: recovering uranium already dissolved in seawater instead of mining it from rock. Its high-surface-area fiber, developed with a leading U.S. national laboratory, passively adsorbs uranium as seawater moves across it. The system is designed for offshore longline infrastructure similar to that used

We're a team of veteran game developers who have come together to build digital experiences with universal appeal, endless fun and enduring meaning. We bring to the task decades of experience shipping world-class titles, from old-school classics to next-generation VR and MR experiences. As creators, we embrace the elements of risk and the unexpected in a game, moments of emergence that leave room for surprise, delight and creativity. At the same time, we know the discipline and judgement it takes to take a product to market, reliably and at the highest quality. Working in mixed reality challenges us to look beyond games for inspiration, to how we live and play in the real world. When we connect with an audience on this level, we can build something with true emotional power and universal appeal. We think it's the game industry's next big adventure, and ours too.
