Energy demand across industries is accelerating at an unprecedented pace, and the need for more deployable, efficient, resilient, and scalable infrastructure has never been more critical. The sustainable energy transition alone demands a 3-5x increase in global electricity generation and consumption. Heron Power is building cutting-edge power electronics for the 21st-century grid. We aim to debottleneck the growth of electricity generation and consumption with scalable, innovative, and less costly hardware solutions, accelerating the electrification of everything.

Cyclic Materials transforms yesterday’s waste into tomorrow’s critical materials. We’re creating a circular supply chain for the rare earth elements and critical materials that power our global economy, without compromising quality or environmental impact. Our proprietary two-phase process is unlocking value from discarded waste. Our REEPure™ technology simplifies the separation of rare earth magnets and critical metals from end-of-life electric vehicles, consumer electronics, wind turbines, and MRIs. Then our REEPure™ technology restores those valuable materials back to their raw form, unlocking new revenue streams for metal buyers and feedstock companies. We are the only high-tech recycling company offering a scalable, efficient, and low-carbon recycling solution that complements mining on both quality and cost, and mitigates the risks associated with extraction. Cyclic Materials is setting a high bar for sustainable resource recovery. We’ve solved the barriers to creating a circular economy for rare earths, and our transparent, data-driven approach ensures the highest standards of sustainability and traceability, including rigorous Scope 3 carbon tracking and water efficiency. With USD $83.5M in funding, including USD $53M in Series B funding backed by partners like Microsoft and BMW i Ventures, we’re scaling our recycling infrastructure across North America and Canada to meet global demand. Cyclic Materials is establishing a more resilient, domestic supply chain for rare earths and critical metals, providing opportunity and value for global industries.
